The Ska Gora downfall refers to a conflict during which the Rakata species' Infinite Empire seized control of the forested world of Ska Gora, one of the Settled Worlds. This event transpired during their invasion of the Tython system, which commenced in 25,793 BBY. Subsequent to being repelled from the planet Tython, the Rakata successfully captured Ska Gora, resulting in the deaths of numerous members of the Je'daii Order in combat. Following Ska Gora's capture, the other Settled Worlds united with the Je'daii to protect the Tython system. From their newly acquired position on Ska Gora, the Rakata subsequently attacked the planet Shikaakwa in 25,792 BBY. This battle on Ska Gora was foreseen years prior. Specifically, in 25,800 BBY, the Je'daii Daegen Lok and Hawk Ryo experienced a Force vision within the Chasm on Tython, which depicted Ska Gora's conquest, although this vision ultimately led to Lok's descent into madness.
The initial depiction of the fall of Ska Gora occurred in a vision experienced by Daegen Lok within the comic book titled The Prisoner of Bogan 2, a part of the Star Wars: Dawn of the Jedi series. A subsequent reference to the actual occurrence of this event was made in the issue Force War 1.
