Cosmic Century is the calendar used in the Knight Run series. Year 0 in this Calendar is the year 2249 of the Common Era or Anno Domini calendar. CC 430, when the series takes place, would be Year AD 2679 by our reckoning.


Hundreds of years from now, humankind enters the Space Age and colonizes many planets. However, common internal divisions and disputes lead to many wars between a divided humanity.

At some point, having already mastered the Faster Than Light warp Gate travel and Black Hole Engine technologies, humans split into four new factions:

  • "New-human-revolution-alliance." An Stratocracy that mainly consists of a people identified as Tiiger.
  • "Ruin." Industrial faction with a system governance based more upon computers and other artificial systems instead of humans.
  • "Human Alliance." A faction that most resembles the current human Government and society in Knight Run.
  • "Innovation Empire." A faction heavily into transhumanism, thriving to make better humans through the advancement of technology. The AUA and AE's paranormal power research facilities could be said to be a descendant of this faction.
  • "Earth." A faction, presumably an extension of the original Government from Earth, which is a long time enemy of the "Innovation Empire" in particular. Implied to be very powerful, it was also hostile to the rest of the factions, forcing them into alliance against Earth. This state of Human civil war persisted for a long time until Beasts appeared.

Before the appearance of High Rank monsters, Beasts didn't have a great advantage in either number or quality of their combat life forms. However, humans didn't take the threat of the Beasts seriously and kept on fighting each other rather than making peace and facing the Beasts as a united force. This allowed the Beasts to steadily evolve their DNA from the repeated battles without much consequence and to grow much stronger in the intervening period.

When the High Ranking beasts were created, they became a true existential real threat to humans. Their energy shields, fueled by an internal Core, gave them substantial advantage in power density and escalated the conflict to a greater order of magnitude.

It was the appearance of Mother Knight who developed AB swords that enabled the Knight Orders to fight on par with the High Ranker Beasts.

After the great war with monsters, all other factions besides Ruin and Human Alliance are destroyed. Earth stays out of contact, with its situation unknown. Much technology was lost, including the theory behind Black Hole Engines.

200 years later, humans (AE and Knight Orders) seemed to be in advantage in their ongoing war with the Beasts. Suddenly, the other side attacked with an astonishing force which culminated in the Battle of Velchees, a highly traumatic war that humans barely won and suffered huge causalities from.

Despite the damage, this victory enabled humans to apparently take the lead again, and brought about a decade of relative tranquility.

Episode Pray takes place at this point.


The webtoon begins with the following narrative:

"Cosmic Century 430. In this era of space travel, humans moved to a vast number of stars and began colonizing other planets... Mankind is at war with monsters." - ME0-Ch1


It has 4 pages. Many detailed Chronological Table informations.


Anne: "Its been 15 years, but the war is finally nearing its end. If the intel is correct, we're on the verge of finally completing the reconstruction of the Gate technology. Once the prototype is finished, it should revolutionize our transportation and defense. What was considered impossible before is now becoming a reality. We managed to destroy most of the warp makers set by the enemy. That should stop any more mass simultaneous attacks from the monsters. Not only that, our recent victory showed that there's no such thing as 'impenetrable'. The only serious problem is whether or not we have enough Knights to last the rest of the war... But if we can recruit more and train them properly, our losses should be minimal".


Dry: "Isn't mankind united because we are faced with the impending death known as Beasts? Ironically, It's thanks to the beasts that we have fewer human conflicts".
Anne: "A series of hellish battles finally ended. An exhausting victory and a short peace are all we earned. But the beasts are equally damaged. So we should be safe for the next 10 years".
Dry: "Yeah. From now on, its the age of humans".

This optimistic thinking wouldn't last long. They didn't know but the Arin attack had already begun.

This battle was an incredible setback for the war effort.

Arin, the most important planet for humans, was taken and the corroded, if the planet could be retaken, the orbital bombardment needed to destroy the corrosion would glass the surface to utter destruction.

The Core Temple, annihilated, forecasting a complete halt for the training of the next generation of Knights. The technologies stored in the Central Order's database were stolen and integrated by the Beasts.

A fearsome Elise Queen appeared, absurdly powerful beyond any other before, together with two EX-Type Zeros, of S and A rank, almost at the very pinnacle of strength.

The Gate Warp Marker codes, the most important technology for humans, vital for any movement around the galaxy, was hacked. Preemptive attacks in multiple planets were launched, crushing human warfare capabilities. Morglay destroyed 4 planetary biospheres, forcing their evacuations...

This was certainly a situation worse than even Velchees only seven years before. The only comparable situation was perhaps, the Fall of Earth almost two centuries before.

  • AD 2153 - War between Earth, Jupiter Union and Republic of Mars ends, The United Government of Solar System created by the victory of Earth
  • AD 2200 - Takion Drive has been invented, started outer space craft.
  • AD 2230 - Commercialization of black hole engine.
  • AD 2245 - Fluctuational gravity field technology has been invented, by the variable of black hole engine and the use of gravity field, stable wormholes succeed.
  • AD 2248 - Start of Cosmic Century
  • Cosmic Century 0 - By the newly invented warp gate technology, many warp gates have been constructed, the new era of human's advance to the outer space started and to celebrate it, the counting of years changes to Cosmic Century.
  • Cosmic Century 1 - From the lead of United Earth Government, the exploitation of resourceful planets starts and the first step of huge terraforming started.
  • Cosmic Century 3 - Start of immigration to other planets, for the past 20 years, space-immigration boom continues on, human population increased rapidly. To gain labor, cloning technology and many other technology has been developed.
  • Cosmic Century 25 - Altai galaxy planet-country announces independence
  • War break between Altai Galaxy and United Government of Solar System for independence - recorded as the first outer space war ever broke.
  • Cosmic Century 30 - Altai and many other galaxies unite to fight against Earth union(including Earth and other planets), The war breaks into small pieces and many forces divide into smaller forces.
  • Cosmic Century 90 - War between planets and Unions, the war for the independence continued on for 60 years and more exploits and wars have been happening repetitively. The technology reaches up to its highest point, most of Great War time's Over technology has been built in this era.
  • Cosmic Century 99 - Humans divide into big 4 forces - Human alliance, Innovation Empire, New Human Revolutionary Union, Ruin. Forces have became stable by this era, but small wars still continued on resource planets. The technologies that have been invented became established. Huge increase of population which led up to human's biggest golden age. But the 4 forces doesn't share technology to each other and creates their own exclusive civilization.
  • Cosmic Century 123 -
  • March - Beasts appear, only planet Idan gets damaged.
  • July - Planet war has been continued on and Innovation Empire get damaged by the Beasts. They only sent a small fleet to defend. Other forces refuse the treaty about co-operating when the aliens attack. Instead of the relation of unknown civilization, they expect Innovation Empire to lose some of their force.
  • Cosmic Century 125 - Innovation Empire suddenly retreats their army from the war against Human Alliance from Kario Galaxy.
  • Cosmic Century 128 - Innovation Empire collapses.
  • Cosmic Century 129 - New Human Revolutionary Union collapses.
  • August - Gate to Earth boundary ceased.
  • October - Doc. Jamil analyses alien's jamming program and calls it Jamil Engine.
  • Cosmic Century 130 - While humans have pretty much no way to fight against the Jamil Engines, which incapacitate most of human technology, Human Alliance starts war against the Beasts.
  • April - Ruin is about to collapse so they create a union between Human Alliance, shared technology and fought against aliens, but they still collapse, alien Queen that absorbed most of human technology started to create huge forces.
  • August - The two collapsed forces' remained forces creates a union, The start of United Assembly which continued until now. Start of the Great War that continued for 100 years
  • September - First Appearance of Elise-type Queen
  • Cosmic Century 218 - More than 10 Elise-type Queens appear which reduces human population to 1/5th of what it used to be, but alien forces also have been reduced. By the middle time of the War Era aliens started using smaller attacking systems, which were created by their miniaturizing technology. High Rank Beasts started to appear. Humans couldn't react to this and they lose most of technology from the era when the 4 forces existed. Knowledge of how to construct Black hole engine technology also has been lost. This is pretty much human's loss of the war, mankind is about to fall.
  • Cosmic Century 220 - Human's unification and correspondence of forces was not good enough. The solider from the old revolutionary union which became a general of main union - David Leonhard - gains a lot of contribution from the war and advances up to the United Assembly. He gains a voice to contribute and forcibly leads army and centralized the power of United Assembly, which created Central Assembly.
  • Anti-Alien force - AE has been created by the Central Assembly and forcibly conscripts many people and appropriates technology to create AE. On the outside, the announcement of creating the AE seems to be about fighting against the Beasts, but on the inside it has been analysed to be an organisation to stop the people who are against the Central Assembly by its elite forces.
  • Cosmic Century 225 - AE starts a huge immigration project for the survival of humans. AE creates law of gate administration and by this time, the AE overtakes the power of Central Assembly.
  • August - By the lead from General of AE - Vumilion Rohagen (not sure about spelling), the president of Central Assembly + Creator of AE, David Leonhard is expulsed from the union.
  • Cosmic Century 227 - Immigration becomes desperate due to planets being eroded by the Beasts, leading up to the new era of war, but because they had no way to fight against High Ranks, humans lost main defense planets - Drian, Sivin, Roam and continue to lose more battles.
  • Cosmic Century 228 - Union abandons planets and assembles together all modern technologies along with pieces of lost tech, creates a space ship full of greatest weapons they could possibly have, many black hole engines and self-sustainable gigantic immigrating space ship - Ion. This project is a large escape mission to another galaxy. AE continues its attempt to fight the Beasts and Central Assembly, which tries to escape from the war, had to conflict their ideas but they forcibly choose to escape. AE had to accept the 1st position guarding of the space ship - Ion.
  • Cosmic Century 229 - Mother Knight creates united health-aid organisation 'PF' and has a plan for advancing technology, they contact Innovation Empire and New Human Revolutionary Union's Bio-soldiers and their galactic researching group, gains support from David Leonhard. The information about treaty of David's support hasn't been revealed, but the analysis says it might have been something about creating a new force.
  • September - PF and Innovation Empire's delegate group Zail's cooperating system was created. from health-aid supporting organisation, they transform into a anti-alien researching organisation. Gains support from one of the old 4 forces - Ruin's weapon company - Ruin Company(anti-alien specialized)
  • Cosmic Century 230 - By the support from Leonhard family, PF union gains license to create an anti-alien researching organisation and allowance of fighting against aliens, names themselves as "Knights" and builds the headquarters on planet Arin, builds Core Temple, accepted a lot of new students.
  • Cosmic Century 231 - Successfully defended Arin and wins a battle against a lot of High Rank Beasts without much damage, which catches people's attention and puts focus on this new organisation, but because they were still on the large galaxy escaping project, this couldn't have been a big revolution.
  • Cosmic Century 233 - Ex-Type Zero Alien Ingrid appeared with Direct Intellection Synchronization type Phenomenon Probability Locking Calculation Weapon - Morglay. This was the first time in history that a phenomenon weapon is used and it attacked immigrating space ship Ion. Ingrid fought and lost, but Ion is destroyed. This was just before people boarded the spaceship so most of humans were still gathered in colonies. Due to this, AE struggled on defense against Beast attacks, but by help of an unidentified force and a person from this force, they finally killed Ingrid. This led to a celebration for the survival of human beings, but also attention from media since this was the first recorded fight of Knights other than from planet Arin.
  • September - Mother Knight reveals one of the very few weapons capable of fighting against High Rank Beasts - AB Swords. Asks for support of AE, which have became government-power focused union, thought that they would need power to stop Beasts which will give them bigger voice on human union and promised to give huge supports. While the unpleasant relationship between AE and Leonhard still exists, AE promised to give support to Knights and aid in operational authority.
  • Cosmic Century 234 - First cooperation between AE and Knights, finally kills Ingrid and the Elise-type Queen number 12 (E-12). By the help of the Union and AE, creates new Knight Orders on all quarters - Western, Eastern, Northern, and Southern Orders. Knights also create an organisation called "Knights Training Organisation" for mostly experimental uses.
  • Cosmic Century 240 - Knights and AE's cooperating technology rebuilt DC element technology which is used to make defensive equipment like DC Coats. AE starts to mass produce DC defensive equipment and provides them exclusively for the Knights.
  • Cosmic Century 243 - Created a private DC Coat by using DC element.
  • Cosmic Century 245 - Establishment of Co-operational Manual for fighting against Beasts, few more Elise-type Queens appear, but fights are successful against them and the main planets are stabilized.
  • Cosmic Century 246 - Operation - "Operation Clear Line" begins - the first counter attack by humans, which is to remove the Beast's bio-warp gate markers that were put in place by them after attacks.
  • Cosmic Century 300 - Operation is successfully done and due to the work of Knights and AE, humans gain some safe boundaries of galaxies. Union, AE, Knights dispatch and create a synthesized defensive line in outer space.
  • Cosmic Century 320 - Gains defense against Beast fleet, who then change their strategies from erosion of planets with EX-Type Zeros to smaller sized, singular ambushing planet erosion.
  • Cosmic Century 331 - First published issue "Knights" magazine.
  • Cosmic Century 368 - E-33(Elise-type number 33) Queen and the first S-Rank EX-Type Zero Beast Satan attack.
  • Cosmic Century 369 - War goes bad for humans, by the continuous erosion, the alien's planet-conquering fortress "Blue Flower" appears for the first time.
  • Cosmic Century 370 - Humans take heavy damage, but finally kill E-33 and Satan. Also destroyed the Blue Flower, but its left over pieces begin to erode the planet again, union couldn't react on it fast enough because of the fatal damage they took from this war.
  • Cosmic Century 371 - Most of the Knights and AE's forces are lost in the war, defensive line retreats.
  • Beginning of Jack Norton chief's "Project Norton."
  • Starting of suppression on Elise-type Queens that haven't been awaken yet by the new factor chasing system.
  • Cosmic Century 380 - Titan Class Battle Cruisers roll out.
  • Cosmic Century 384 - Norton Class Battle Cruisers roll out.
  • Cosmic Century 386 - Norton fleet joins the second suppression of Elise-type Queens that haven't been awaken yet.
  • Cosmic Century 395 - Humans finally gains their boundaries back and rearranges them after the long fight with new fleets using Norton Class ships.
  • Cosmic Century 400 - EX-Type Zero "Rabbit" appears on Tobal. Knight Lime fights against him and Rabbit retreats.
  • Cosmic Century 413 - EX-Type Zero Rabbit attacks Gate near planet Arin by himself and then disappears.
  • Cosmic Century 415 - Beast's attacking strategy changes become more subdivided, using separate Plants. Many more Knights die in war by this strategy.
  • Cosmic Century 418 - Uses new Gates and use of observing system, the absolute defensing boundary operation begins, AE and Knights lose many more people. Use of new ambushing strategy by High Rank Beasts creates local wars that lead to much more human deaths. This is when Pray and Anne were Knight trainees.
  • Cosmic Century 420 - Beasts attack main planets to stop the defensive boundary operation and many Queens create a united army of Beasts to attack humans.
  • Cosmic Century 422 - AE and Knights starts huge counter-attack and start of operation to reclaim the colony which has Ruin's experimental bio-laboratory against Beasts, succeeds after 3 months.
  • January - E-99, E-101 Queens appear, corrupt 5 planets using corruption Plants. SS-Rank twin EX-Type Zeros Cross Eyed Alpha and Beta appear and they both wield a new Direct Intellection Synchronization type Phenomenon Probability Locking Calculation Weapon - Balisarda. This begins the Battle of Velchees, 137 fleet exterminated.
  • August 4th - Defeated the two Queens, Cross Eyed Beta is defeated by Anne and Pray, while Cross Eye Alpha retreats. Victory of Battle of Velchees.
  • Alien experimental organisation P.P.P is established, long term Anti-Beast war experiment starts.
  • Cosmic Century 423 - By the support of experimental organisation P.P.P, manual of Anti-Beast war is re-established, using all left over forces, removed all the Beast's warp gate markers and defends main galaxies using all forces to regain the defensive boundaries.
  • Cosmic Century 424 - P.P.P, Arin force, Central Order, Northern Order, and Giass (not sure about spelling) all cooperate and create Direct Intellection Synchronization type Phenomenon Probability Locking Calculation Weapon and the ship Alcyone, used for exploration to central Beast nest.
  • Cosmic Century 430 - After many wars, humans finally gain Absolute Defensive Boundary back. As a celebration, Union and Knights proudly announce "The Age of Human" with huge festivals.
  • Queen E-34 appears, planet Arin erodes, Central order is annihilated, and Mother Knight disappears.
  • Planet Valtia gets attacked by Beasts, EX-Type Zero Fear uses Phenomenon Weapon - Morglay to attack military base Eden. Four planets total with large scale basses are attacked using Morglays - Naricapha, Dalita, Puyan along with Valtia.
  • In response to loosing contact with Central Order on Arin, Dry Leonhard takes over leadership of AE and temporarily creates new united fleet with 4 black hole engine ships.
  • Cosmic Century 430.12 - Many Blue Flowers appear, 2 EX-Type Zeros appear - Blue Beetle who wields MJOLNIR and Fear who wields Phenomenon Weapon - Balisarda. The worst war possible breaks out. Knights Dry Leonhard and Anne Mayer combined efforts finally defeat both Blue Beetle and the 1st S-Rank special imitated Queen E-34. The corruption of Arin continues and the Beasts still fight, but due to the death of E-34 and subsequent retreat of the sole remaining commanding EX-Type Zero Fear, the fighting and production capability of the remaining Beasts is greatly reduced.
  • Cosmic Century 432.8 - The war continued for 2 years and 6 planets are abandoned, but the union won the war. Four Blue Flowers are destroyed, but 80% of union's fleets are destroyed as well. All remaining Blue Flowers retreat and warp off to distant space after the death of E-34. Because there's no more commanding Beasts on Arin, the threat of another strike seemed to be very low. The third EX-Type Zero "Quatro" created by E-34 is missing from its artificial womb, it's thought that Fear retrieved it when retreating. Arin is abandoned.
  • Cosmic Century 432.12 - As Eastern Order to be the basement, the Temporal Order that is replacement of Central Order is built. The president is Dry Leonhard. Northern Order is against the announcement of making the Temporal Order and Southern Order refuses to answer until they find Mother Knight, but every organisation agrees with Temporal Order being an organisation that looks after the Knights Training Organisation. However, problems of facilities makes the other Orders decide to run their own mid-sized Knight Training Organisations instead. AE was against Mother Knight's forcible way of running the Knights, but finds out that Dry Leohard might be a better person to be the head of the new Knights, so AE announced to support him.
  • United Assembly announces that they're not pleased with the relationship between AE and Knights, but AE's head general Purl Meray (not sure about spelling) and one of AE's main force - Pirin (not sure about spelling) defensive fleet's general Rinel's (not sure about spelling) strong support made Central Assembly incapacitate.
  • Cosmic Century 433.1 - The new union between AE and Temporal Order bill has been passed which is based on the team from Pray War. Many unions and planets like Valtia and Northern Order were strongly against it, but the bill passes. The Zail Family from Central Order were also against this bill and become a part of Northern Order instead. The Zail's cut their acquaintance with Leonhard Family, which had existed for a long time.
  • Support to P.P.P stops from United Assembly. Ruin and Eastern Order create a new Anti-Beast experimental laboratory D.O. Innovation Empire and New Human Revolutionary Union's special force related experiment restarts, which had been stopped because it was very inhuman.
  • Cosmic Century 433.5 - Because P.P.P couldn't get any support from Central Assembly, the chief Anne Mayer gains support from planet unions that are against new union and changes the name of the organisation to "Aegis" and starts the project of "Machine Society". Ego existing dolls that have gone through the special law of pilot-less producing doll community and special unit "Yggdrasil" which is hidden in secret is built in smaller numbers than it was projected before and been sent to outer space where it haven't been explored yet. Anne Mayer gives all of her authority to Dr. Thor after this project and disappears.
  • Cosmic Century 434 - Giass Industry and Ruin company union bill is announced. After losing the technique to produce AB element, Knight gives more authority to D.O to make a new element that can replace it. This experimental organisation's delegate is Dr. Duran McGroover.
