The Cursed Tome of Mar-Karakor

Scowling as his companions scooped handfuls of coins into their sacks, Felaster did his best to ignore their frenzy as he peered intently around the great Vault. If the legends were true... Yes, there it was! He brushed a coil of threaded pearls aside, and lifted up a dusty book, bound in some strange copper-hued hide. A simple rune in the center of the cover confirmed the legend as true - Felaster held in his hands the long-lost Tome of Mar-Karakor.

Soon they would be safe, back in the City-State, and Felaster would be free to decipher and master the secrets of the Tome. That is, so long as madness didn't claim him first...

Mar-Karakor was a master of black sorcery in the Elder Days, and developed several foul arcane formulae of his own. The spells in the tome are difficult to master, and take an awful toll on the student's psyche. Each time a spell is successfully mastered, the Magic-User must roll a d20. If the result is a "1", he permanently loses a point of Wisdom. Furthermore, the spells are decidedly in the realm of Black Magic, and the DM may rule that mastering all seven of them results in an alignment step towards Chaos or Evil....
