Devilin, The First Born
The most unnatural of the Ancients simply because he is so mundane in comparison to the others. Devilin lacks any and all extra-sensory abilities, his metamophic abilities are next to nil, and the sun doesn't effect him near as badly as it does the others. His dexterity, speed, and stamina are a cut above the rest, however. Also, for what Devilin lacks in preternatural abilities he makes up for with a razor-edged intelligience. These two things combined make him a very formidable opponent.
In current times Devilin fancies himself a businessman... and a mob-boss. He is a wealthy shareholder in nearly any and every business with a substantial amount of yearly income. Microsoft, Sony, Time-Warner, et cetera. He is, quite truthfully, the wealthiest, and yet most unknown, man in the world. Considering his longevity, being a known figurehead in the business world would prove to be his downfall, and thus Devilin works through intermediate officials in his current employ. Namely varying presidents and VIPs in the companies he either owns or holds a large stake in. His current powerbase is New York City.
