Since the fall of the Lazax Empire, the galaxy has been plagued by thousands of years of chaos, war, and isolation. Now, finally, the once-great civilizations have restored some semblance of their former glory, and have cast covetous eyes on the wider galaxy once more. This book explores the Twilight Imperium setting as established in TI 4th Edition and Prophecy of Kings. It provides a canonical, in-depth look at the setting in the way that only a roleplaying game can do. Fans of Genesys, fans of Twilight Imperium, and fans of thrilling and heroic adventures in a sprawling and rich space opera setting should all love this book.
