Folken Fanel is Van Fanel's older and only brother. Folken abandoned Fanelia after being sent out to retrieve a drag-energist as his right of passage to becoming king. He joined forces with Emperor Dornkirk and the Zaibach Empire in hopes of ending war (through war, ironically). He is torn between his roles as commander and brother, a conflict which is resolved by the end of the series.
(The Strategos or tactician of Zaibach, Folken is revealed to be Van's older brother and the original heir to Fanelia. After he failed to kill a dragon, he lost an arm to the beast and was later picked up by the Zaibach, who nursed him back to health under Dornkirk's instructions and fitted him with a mechanical arm. He originally joined the empire in hopes of realizing Zaibach's ideals of a world free of war...)
For all that for the first few episodes of the series Folken seems like a rather heartless, robotic devote of Zaibach's regime, he reveals himself to be a profoundly brilliant and compassionate man. He is an engineer, a sorcerer, a chemist, and a strategist of a caliber paralleled only by Dornkirk himself. He is a true archetypal tragic villain; he truly does think that what he is doing is for the greater good. Ultimately, his desires go far beyond merely wanting to eliminate war—he wants to re-create the very laws of "fate" governing a world he sees as otherwise doomed to seep itself in needless tragedy.
