Jasper Flint has been breaking into places he shouldn't be since he was old enough to pick a lock — which, according to him, was the age of six when he liberated a meat pie from the baker's locked pantry in the slum district of Greyhawk City. He graduated from petty theft to tomb robbing after a chance encounter with a retired adventurer who paid him handsomely to retrieve a family heirloom from a trapped burial vault. Jasper discovered he had a natural talent for reading ancient architecture: the subtle seams that indicated a secret door, the discoloration that betrayed a pressure plate, the draft that suggested a hidden passage. Over the next fifteen years, he built a reputation as the best dungeon delver in the Flanaess — a man who could get into any tomb, find any treasure, and get out alive. He has the scars to prove it: a missing pinky finger from a needle trap in the Ghost Tower, a patch of acid-scarred skin on his left arm from a trapped chest in White Plume Mountain, and a permanent limp from a pit trap that almost killed him in the Ruins of Castle Greyhawk. When he heard that the Tomb of Horrors had claimed another adventuring party — the third that year — Jasper saw not a warning but a challenge. Every thief in the Flanaess knows the Tomb's reputation; the one who cracks it becomes a legend. Jasper intends to be that legend, though he's pragmatic enough to bring competent allies rather than attempting it solo.
