A man driven.... but by what?
Enigma knows much, tells little, and generally annoys a lot of people. No one knows what his real name, or even if he has a real name, or why he's doing what he's doing.
A black crystal which seems to able to summon forth a plethora of weaponry; his favorite seems to be a black katana.
All that is known about Enigma is that he was a member of the Brotherhood at one point, but his position in the Brotherhood was unclear. He seems to respect Rune a lot, and appears to be an ally of the Ultimate Organization... but, then again...
