The Slayers Three, a trio of hunters living during the Galactic War, originated the Spawn Nebula.
During the Galactic Civil War, the Kaarenth Dissension maintained a starfleet in the Spawn Nebula, for use in battle against the New Republic. Dissension forces also constructed a space station to keep its vessels in constant readiness. A member of the Dissension, Meres Ulcane, was discovered on Betha II by New Republic agents, and fled to the Spawn Nebula. The New Republic tracked him, and engaged the Kaarenth Dissension. The resulting operation saw the destruction of the repair station and much of the Dissension fleet.
