From publisher blurb: The Great Shadow is an introductory adventure to the Trudvang Adventures, giving you a taste of the setting and the game. When three children are kidnapped from River's End, a small village in Dain, the locals ask the player characters to help them find them. Their investigation might lead them to the Great Shadow. This module is designed for 4-6 level 1 characters. You do not need anything more than this module to enjoy the story, but if you wish to enjoy Trudvang Adventures to the fullest, make sure you get the Trudvang Adventures Hero Companion and Trudvang Adventures Setting Companion. It should take 1 or 2 sessions to play through the module.
