From the Inside Cover: Canadian adventure written for a universal mechanic described in its introduction although the recommended "levels 4-7" and character/encounter stats indicate strong xD&D compatibility. Adventure is set in a Medusa's lair, formerly a goblin palace but recently raided by an evil magician with a gnollish horde, with an extended backstory and setting detail.
