TSR AD&D Monstrous Arcana Masters of Eternal Night Module

TSR Advanced Dungeons & Dragons Monstrous Arcana Masters of Eternal Night Sealed Module is the second in a trilogy (originating with A Darkness Gathering and concluding with Dawn of the Overmind). DMs can run this adventure by itself or link it with A Darkness Gathering and Dawn of the Overmind to form a seamless epic-length adventure spanning all three modules. The illithid trilogy supports The Illithiad, a Monstrous Arcana supplement that provides invaluable information on illithids and their vile purposes. In Masters of Eternal Night, adventurers travel across a frozen landscape to stop the deadly mind flayers in their quest to extinguish the sun. Deep in the secret heart of a snow-covered crater, the player characters must unearth an ancient alien object. Only with its powers can the PCs hope to end the illithids' bid for ultimate domination.
