From publisher blurb:
Welcome to the Game of the North – the Tomb of the Fifth Colossus is a module intended to introduce the system and the rudiments of the broader setting called The North. Each Referee and each player in the North will create their own narrative, their own adventures. This module is intended to give insights on how to run the game and how to play the game while providing a setting, an adventure characters, gear & backgrounds for ease of play.
If you are running this adventure you can feel free to read the entirety of the module and all of the pre-generated characters & monsters records.
If you plan to play as a PC in this adventure and its further campaign you shouldn’t read much further. You’ll want to select one each of the accompanying materials – you’ll want one Character, one Gear Sheet and one of the Your Story So Far sheets. You can and maybe even should randomly select each of these.
