Events

 * The Galactic Republic —allied with the Alsakan Alliance, the Hutt Empire, and the Chiss Ascendency— makes its final strike to the Legion's core by invading their remaining territory (located deep in the Western Reaches). They obliterated the remaining Legion forces in the Mid Rim and quickly attacked in four differents fronts.
 * After destroying all Legion space defences, the Great Alliance engages the apocalyptic Battle of Skyfront, which lasted for months. In the endgame of the battle, the giant spacestation was completely occupied and destroyed by the inside in an act of heroic sacrifice of the allied forces.
 * The Supreme Intelligence Core was finally destroyed along with its giant mechanical world. With the hive mind death, the Legion was completly destroyed and the 405-year-long war againts the machines came to an end.
