This is why I never really used Eden. I prefer using GF's that I can put a personality to, sort of fitting the little story that goes on in my head.

I like the little theory that it is shaped to look similar to the Gardens in the game. The Garden of Eden - get it?

Also, according to the Ragnarok's origins, the Centra legend of the Dragon Ship, Eden may be the legendary Dragon Ship itself, and it could be assumed that due to the "Garden" theme of the schools, this is the oldest Centra weapon and thus why it carries the name.
