The Babylon Project

The Minbari Starbase was a large facility used by the various clans of the Minbari Warrior Caste as a platform from which to stage the offensive and defensive strategy during the First Shadow War. Towards the end of the war, following numerous incidents of infighting among the military clans, the tide had turned against the Minbari and their Starbase was destroyed by the Shadows.[1][2][3]. Short time after it's destruction, a Minbari named Valen appeared with a new starbase, which was in fact Babylon 4.
