Sigil and the doorway to nowhere
Vorgyrn grew up mostly on Sigil, which worked somewhat to mitigate the upbringing present in Drow society. Not to say it was erased completely; constant distrust and a slight feeling of superiority persist. When he manifested sorcerous powers, he took great pains to conceal these, practicing openly with a crossbow and daggers while secretly bending the laws of physics to his whim. Work as a mercenary has mostly defined his professional life, where a surprise blast of fire or ice could give him the upper hand against an unsuspecting foe (or employer, as the occasion warrants). When the situation calls for it he works with a team, hired from one of the various outfits on Sigil and handpicked by Vorgyrn for the task at hand. His latest employer had him investigating (read; breaking into and grabbing anything that seemed important from) skulk bases of operations, in order to learn more of their plans.
