Dungeon Module 1: Crypt of the Lilac High Priest

From publisher blurb:

CRYPT OF THE LILAC HIGH PRIEST contains two dungeon level maps, a large-scale hex map, introductory information, and detailed encounters keyed to the dungeon maps. This module presents a complete dungeon for 1st-level ADVANCED DUNGEONS & DRAGONS characters, intended for use by experienced Dungeon Masters. It can be used on its own or as the first stage of the sixteen-part QUEST FOR THE TEETH OF DAHLVER-NAR. Luigi Castellani's cover art depicts a veteran, a prestidigitator, an elven veteran, and a dwarven veteran preparing to attack a "sphere of many eyes" (cf. encounter area 22 within).
