The Siege of Kalee was an invasion of the planet Kalee in 129 ABY by the Fel Empire during the Sith-Imperial War. Led by a Kaleesh warlord named Nyax jal Sk'ar, the Kolkpravis defended the planet against Imperial forces, until Admiral Zevulon Vao ordered an orbital bombardment of it. Following the battle, stormtroopers were sent to capture Nyax, as Vao was impressed by his skills.
