The Night War was a war starting with the First Battle of Telos and ending at Borleias. Reven brought up his army by using Sith ships that survived the Jedi Civil War. The war ended when Darth Scuro, Commander of the Grand Army of Scuro, was redeemed and he defeated the Sith army he built, which was then headed by Darth Tyragus, at Borleias. Originally, Scuro led the Sith and Elsa Palleon led the Republic. The Night War also marked the first use of Jedi Night-Troopers, which contributed to the name of the war(and that Darth Scuro's name was Reven Night).
