From publisher blurb:
The Mermaids from Yuggoth Attack!
Your players have ransacked dungeons and slain mighty beasts, rescued the helpless and thwarted the sinister plans of demons. But they have never seen anything like the strange items, blasphemous rituals, or horrors that await within these pages.
Lurking herein are twelve short encounters for the Dungeon Crawl Classics roleplaying game. Judges can use these scenarios as one-off’s or as jumping-off points to further wierd pulp adventures. Each encounter includes a unique monster, and the book is packed with treachery, novel twists, and horrible predicaments. Whether it’s the Squid Sorcerer, Umbo the ape witch, or Malagok the Creator Beast, these encounters recall a tradition pre-dating orcs and elves when the pulp fantasy realms were just weird.
