Clan Invasion (3050–3061)
A mysterious invading force strikes the coreward region of the Inner Sphere. The invaders, called the Clans, are descendants of Kerensky’s SLDF troops, forged into a society dedicated to becoming the greatest fighting force in history. With vastly superior technology and warriors, the Clans conquer world after world. Eventually this outside threat will forge a new Star League, something hundreds of years of warfare failed to accomplish. In addition, the Clans will act as a catalyst for a technological renaissance.

BattleTech is a science-fiction “space opera”: a factional, militarized universe set in the thirty-first century, a future where humanity has spread to the stars and spawned titanic interstellar empires, each nation controlling hundreds of worlds across a region of space stretching a thousand light years and beyond.
Initially published over thirty years ago as a tabletop board game, BattleTech has gone on to become one of the gaming industry’s most important and longest-lasting science-fiction universes.
