Prison of the Hated Pretender is an introductory adventure for 4-6 characters levels 0-1. Originally published on the Dungeon of Signs blog, it is a short drop-in location-based adventure with a couple of interesting puzzles, a lack of "book" monsters, implacable foes with an obvious weakness, and a very weird roleplaying opportunity. The new 2020 edition republished by Hydra Collective adds suggested guidance for new Dungeonmasters who grew up with 5th edition and don't know how old-school works. Stats for both BECMI and 5th edition, and setting neutral (though there are some implied things about the history of the world).

Adventure in a desolate magic-stained wasteland where fabulous crystal spires and fortresses plummet from the skies to tempt the desperate and the bold with magical gems and golden treasures. Find your fortune or find your death as you plunder the fallen sky tomb of an Empyrean despot. SCHEME with the unnatural denizens of the Crystal Tomb! UNRAVEL the secrets of the Dead King and his realm of misrule! LOOT strange magics and Opulent Treasures from beyond the sky's vault! A complete adventure for Level 1 characters and an introduction to both the dungeon crawl style play and the Crystal Frontier setting. Written with the new referee and players unfamiliar with older style games in mind, Tomb Robbers of the Crystal Frontier is built to start a campaign, use as a one-shot, or to drop in as an adventure locale in almost any fantasy world. The adventure has been designed for and tested with OSE, but is easy to use with any of the wayward offspring of the early editions of the first fantasy roleplaying game. Tomb Robbers of the Crystal Frontier emphasizes problem solving, faction intrigue, and exploration in the tradition of classic dungeon crawl adventures, but with a phantasmagoric fantasy Western aesthetic. NOW AVAILABLE FOR ERRANT AND OLD SCHOOL ESSENTIALS!
