The United Warlord Fleets were an Imperial faction, which was formed in 12 ABY after Admiral Natasi Daala executed thirteen Imperial warlords at Tsoss Beacon and merged their forces into a combined command, with herself as leader. Daala subsequently led the faction in an attack on the Jedi Praxeum on the moon Yavin 4, but she was defeated and her flagship, the Super Star Destroyer Knight Hammer, was destroyed. In the aftermath of the battle, Daala resigned and control of her forces passed to Admiral Gilad Pellaeon. The new Supreme Commander led his forces out of the Deep Core and merged them with surviving Imperial Rim factions to form the Imperial Remnant.
