Candlekeep Mysteries is an adventure anthology for the 5th-edition Dungeons & Dragons ruleset released on March 16th, 2021. It features a collection of many mystery-themed adventures based around Candlekeep, the great temple-library.
Candlekeep attracts scholars like a flame attracts moths. Historians, sages, and others who crave knowledge flock to this library fortress to peruse its vast collection of books, scribbled into which are the answers to the mysteries that bedevil them. Many of these books contain their own mysteries — each one a doorway to adventure. Dare you cross that threshold?
