From the back of the book:
Welcome to ‘Into the Long Dark Night’, the first adventure module for the Falling Stars Roleplaying and Tactical Game.
This book will introduce you, the players, to the world of Falling Stars and lead you through a narrative story that is shaped and driven by the players. The story that is outlined here-in is just the skeleton of a narrative. It is up to you, the players, to fill in the connective tissue, skin, and effects that will make it a living, breathing entity all its own.
So, grab between two and eight of your closest friends, get some refreshments, and get ready to dive into a world of adventure and intrigue, shaped by your own actions.
