Mission to the Dassal system

In 34 ABY, Commander Poe Dameron and Kazuda Xiono undertook a mission to the Dassal system, a star system Xiono had identified during his mission on the Colossus, which the First Order had apparently been active in. With their droids, BB-8 and CB-23, they discovered that the Dassal system's sun was missing, and all of its planets had been cored out. On a formerly inhabited moon of the only perfectly-cored planet, Dameron and Xiono discovered an abandoned village, which they deduced had been the site of a massacre of some kind. The Resistance members were spotted by a probe droid, and its destruction drew in Major Elrik Vonreg and his squadron of TIE fighters. Dameron and Xiono escaped their pursuers by luring them into the gravity well in the center of the cored-out planet, destroying Vonreg's squadron, and departed believing they had killed Vonreg himself as well. Dameron and Xiono swapped out their droids, with BB-8 returning to Dameron, before Xiono returned to the Colossus platform and Dameron departed on a mission to Jakku.
