Rebellion Sourcebook (Megatraveller)

The Rebellion Sourcebook was published in 1988 by Game Designers Workshop as a foundational supplement for the MegaTraveller role-playing game system. It was designed to transition the Traveller universe from its original setting into a period of dramatic political upheaval known as the Rebellion. This period marked a significant narrative shift, moving the game away from the static, established imperial order of the Classic Traveller era and into a fractured, war-torn landscape that allowed players to engage with the decline of the Third Imperium.

Authored by Marc W. Miller, the creator of Traveller, the sourcebook serves as both a history lesson and a campaign framework. Its design emphasizes the complexity of feudal interstellar politics, utilizing in-universe propaganda and historical documents to immerse players in the chaos of a civil war. Upon its release, it was received as a bold, if controversial, departure that fundamentally altered the canon, reflecting the company's desire to evolve the game's scope through high-stakes narrative conflict rather than minor tactical encounters.
