The ex-Force Hound Xesh came up with a plan which involved the assassination of Predor Skal'nas and cause his generals to fight each other for dominance. Using his Force Hound training, Xesh managed to locate Skal'nas' base of operations and launched an attack on Ska Gora.
However, this was revealed to be a trap as the Rakatan forces ambushed the Je'daii task force and took many of them prisoner before encasing them in tubes in a chamber under the Rakatan fortress.
