The Battle of Mortis was a brief fleet engagement between the New Jedi Order, the Jedi Exiles, and the Ranquell Peace Commission of the Galactic Alliance near the planet Mortis.

The Jedi and Jedi Exiles both laid claim to a sacred temple on Mortis late in the Second Jedi Civil War and began a ferocious space engagement over the planet. The Alliance forces arrived to stop the conflict, however, and forced the Jedi surrender. With this accomplished, Mortis was subjected to planetary bombardment and destroyed to prohibit the Jedi from fighting over it in the future.

The foolhardy attack on Mortis, however, resulted in the annihilation of both fleets- and much of Wild Space and the Mid Rim, for that matter.
