Adventure amongst the shards of a broken Empire!The Keleres were established by the Council in the wake of the discovery of the Mahact Kings, and the realization that not one, but two existential galactic threats had arisen in a matter of months. In theory, the Keleres are empowered by each of the members in the Galactic Council to investigate matters that concern the Pax Imperalis, enforce the rulings of the Council, and stop threats to the galaxy as a whole. Each of the Great Civilizations of the Council provides personnel and equipment to accomplish this. In practice, however, the Keleres are underfunded and understaffed. They are distrusted by the various peoples they must investigate, blocked at every turn as the Great Civilizations pursue their own agendas, and riven by factionalism and infighting. However, they are often the only ones who stand between the galaxy and threats that could end the lives of billions of innocents.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.
