The 7th Colony of Arin was built near the Gate and resource asteroid, Kuran.
It functions as a temporary residence that serves as a relay point for those who use and manage the Gate. Its second purpose is to serve as a base for AE, who controls the colony.
A shielded, military spec, space colony which has a design that allows for gravity generation through rotation. It is shown to have large transparent windows in the primary habitat area which can be covered by reinforcing petals, as shown in the picture.
E-34 only sent a single ship, a Number 387 special warfare type Beast, which pierced the shields and hull with a particle beam, then launched multiple pods inside through the breach, including a High Rank Type 77, who engaged and was eventually defeated by Jill McKellen.
Role in the Second Battle of ArinEditSpace Colony 7 became a staging base for the scattered AUA forces after the fall of Planet Arin, the normal unskilled civilian population evacuated with the Turin Terraforming fleet.
When Admiral Norton staged the diversionary attack for Anne's planet fall, Space Colony 7 was launched as a huge projectile at the primary Beast Plants on Arin, it's three management AI's disabled to prevent Beasts overtaking the station and internally guarded by Knight Jill McKellen and DC Coat equipped, "Vivid" Anti-High Rank Dolls.
With the synergistic power of Flagship Alcyone's ancient SCR Drive and Black Hole Engine stabilized with the colony's massive energy field stabilizers, it gathered too much kinetic energy to stop. Also the High Rank invaders were too late to disable its engines, being stopped by Jill. As Space Colony 7 plunges towards Arin, it smashes through the Beast defense line.
Despite all this, EX-Type Zero Blue Beetle appears once again and she is in control of the First Class Anti-Fortress Armor Type 7 Gravity Cannon. A single shot cores the colony, shredding it and simultaneously disperses its built up kinetic energy.The pieces of Space Colony 7 still rain down however, too numerous and dense to be destroyed by units in the atmosphere. The Beasts then reveal an All Purpose Invasion Type Fortress "Blue Flower" and its overwhelming number of armaments destroys the remnants of the colony.
