Laveth, Lolth's half drow daughter, is plotting to seize power from her chaotic evil mother.

A shrewd, spell-using green dragon has taken over the deepest chamber of a limestone cave as his lair. The dragon has persuaded a tribe of troglodytes to live in the outer chambers as a sort of "protective buffer" in return for gifts of magical treasure. The troglodytes cherish the useless bits of magic without realizing their modest worth. The outer chambers of the cave are protected by the troglodytes, the beetles and centipedes the troglodytes raise as cattle, and wild creatures. The green dragon uses traps, illusions and magical devices to protect his inner chamber. Wyrmhaven is the second dragon's lair to conquer. Part of TSR 1073 The Dragon's Den
