Trials of the Trapmaster's Tomb

From the back cover:

Long ago, these wildlands were home to the Trapmaster, Hoysib Mov. A sorcerer, a necromancer, and an engineer of lethal skill, Mov developed the deadliest traps and then peddled his creations to the highest bidder. The vile death-merchant used his wealth to create and bait his own tomb filled with his favorite inventions. But is this an egotistical post-mortem challenge or is there a more sinister, necromantic purpose? Once a decade, the door to his resting place opens for a single day, admitting those desperate enough to attain the riches within by enduring the Trials of the Trapmaster's Tomb!
