- This article is about the mass migration from Terra in 23rd century. For the Exodus of the SLDF from the Inner Sphere, see Operation Exodus.
After the maiden flight of the TAS Pathfinder and its arrival in the Tau Ceti system, the Terran Alliance established its first colony on Tau Ceti IV.
The First Exodus ended with the Outer Reaches Rebellion and the subsequent withdrawal of the Terran Alliance to a 30 light year territory around Terra.
