BattleTech: Universe - Lore Sourcebook

A hardcover lore compendium distilling more than 1,000 years of BattleTech's future history into a single reference — the Star League, the Succession Wars, the Clan Invasion, the Civil War, the Jihad, the Dark Age, and the ilClan era.

It profiles the Inner Sphere's Great Houses, the Clans, the Periphery states, and notable mercenary commands, making it the recommended entry point for players wanting to understand the setting behind the tabletop game.
