Clan Invasion

The Clan Invasion (officially called Operation REVIVAL was a massive incursion into the Inner Sphere by the forces of The Clans between 3049 and 3052.

It is one of the most significant events of Battletech History, as well as one of the most explored.

Prelude

In Clan Space in the early 31st century after two centuries of growth, there was increasing pressure by the Crusader Faction to return to the Inner Sphere and restore Star League. The Warden Faction had managed to stall efforts through various means, from sending the Wolf's Dragoons to spy on the Inner Sphere and various other stalling tactics. Given that even the Capellan Confederation still outnumbered the totality of The Clans by a significant margin this was a reasonable position to make. Never the less, eventually things came to a head in 3048.

One of ComStar's side projects was the Exploror Corps, a fleet which probed beyond the Periphery in part to see what happened to the Exodus Fleet. The Explorer Corps ship Outbound Light eventually found the answer to that question in the worst way, having stumbled not only into Clanspace, but also onto the capital system of Clan Smoke Jaguar, who were both staunch Crusaders and general assholes. They captured the exploration ship, interrogated her crew and told the Council that the Inner Sphere had found them and it was the time to act.
