From publisher blurb:
Aeons ago, the forces of Apophis defeated the great paladin of Isis, Nephabti, and imprisoned her in stasis in a hidden tomb, along with those that had failed Apophis. Somehow or another the PCs have stumbled across the tomb.
EG1 is an Egyptian inspired adventure with Lovecraftian elements for the first edition of the world's first fantasy role-playing game (character levels 5th to 7th), though can be easily used with any classic edition or OSR game. Also includes about a half dozen new monsters and magic items.
