Technitions. Techs. Yea, this counts as a Walker class. Sort of. Well, basically Techs don't like fighting on the front lines. Or they may be freaks about it, who the hell knows, but the point is they use technologies to fight or support other fighters. The Elves Of Iga Shina have the best techs in the world right now, ya know, with the whole invention of a mana-powered battle suit. Basically, these guys are needed for any conflict, big or small, and without them, I can't honestly say any of us would be alive today.
Things to know about Techs -
-They can interact with any known machinery or user interface.
-Can hack into magical rune interfaces and elven mainframes.
