Duel of Zammer was the final battle in the Galaxy between the last four Jedi and Sith against Jonah. They surrounded Jonah who leaped into action. Jonah quickly killed each, taking only ten swings to kill the three Jedi. The Sith barraged him with lightning until Jonah absorbed so much of it, that he blasted the Sith about fifty feet. He then beheaded him. Jonah then committed suicide, which ended the Galaxy in 25,025 ABY.
