Books are condensed collections of knowledge. Knowledge is power. Power corrupts. As any physicist will tell you, power is a function of energy, and energy and mass are interchangeable. Put enough books in one place and it distorts the world... My favourite, slightly tongue-in-cheek description of Emmy Allen's foundational pointcrawl is "roguelike". The Library is infinite and extraplanar; each time you go through its doors you'll generate a wholly new layout. You know the setup well already: the deeper you go, the greater the challenge and greater the rewards. This gorgeous 160-page, hardbound adventure, complete with a foiled front cover, is a wonderful toolkit for your zero-prep sessions. It's statted generically for dungeon crawlers and old-school systems, so it's easy to convert to your game of choice, be it Old School Essentials, Into The Odd, or Cairn. The Stygian Library is a partnership between SoulMuppet Publishing and Dying Stylishly Games. Illustrated by Alec Sorenson.
