Powers and Abilities Edit
Number 680 emits a defensive barrier powerful enough to reduce the erosion ability of Mysteltein. Upon being commanded to release, the outer blade cladding separates away from the core and reforms back together around the body of the user to create a suit of armor.
After this process occurs, a Great sword is what remains at the core. It's blade bears the Latin inscription "Letum non omnia finit" which means "Death does not end it all".
Inside this Great sword is an even smaller, final sword which resembles a Jian.
First appears in AE2 - Ch2 and the special armor ability is shown in AE2 - Ch81.
