Illfrost: Quick Start Guide
A campaign supplement for a gritty fantasy adventure set on the frozen continent of Lannithir, approximately a century after the fall of western civilization. It provides Dungeon Masters with the setting information and resources needed to begin a campaign with minimal preparation, while supporting player character and background creation. Using Dungeons & Dragons 4th Edition mechanics, the campaign is designed to take characters from 1st to 30th level. Players face new monsters, harsh conditions, and a malevolent threat while struggling to survive in an unforgiving frozen world.
