The Crypts of Terror

From the back cover:

Fire*Wolf, exiled from his Barbarian village, has inherited both his unknown father’s name, Lorn Xandine, but also - unwillingly - his role as a sorcerer. He must also face his father’s enemies. He will need all his skill, and his father’s spells, if he is to survive and successfully combat the most dreaded foes on earth: the Demonspawn.

Standing in the ruins of Belgardium, Fire*Wolf knows that his most dangerous adventure is only just starting. Only you can decide whether he will be truimpant or perish.
