In the Yatil Mountains south of Perrenland there is rumored to be a magical hoard of unsurpassed value, a treasure of such fame that scores of adventurers have perished in search of it. Find the perilous Lost Caverns of Tsojanth and you may gain the hidden wealth of the long-dead arch-mage-- if you live. Module S4, this contains a brief wilderness journey to the caverns, but the bulk is underground. The caverns are noted as a previous lair of the Arch-mage Iggwilv- though she is long gone, her Demonomicon remains. This module marks the first appearance of several monsters and items that would later appear in the Monster Manual 2 and Unearthed Arcana. A labyrinth features in the caves. TSR 9061
