Around 25,793 BBY, the Tython system was invaded by the Infinite Empire of the Rakata species. The invasion was led by Predor Skal'nas, who sought the Infinity Gate believed to be on the planet Tython. The Infinite Empire devastated the Settled Worlds, but the allied Je'daii Order and the Settled Worlds' forces offered resistance.
The Rakatan Infinite Empire's forces launched an invasion of the Tython system circa 25,793 BBY. Skal'nas aimed to regain his species's dwindling control over the Force by seizing the Infinity Gate, which was rumored to be located on the planet Tython. His forces attacked Fury Station, a space station at the system's edge, before capturing the gas giants Obri and Mawr both. The Je'daii Order repelled the attack on Tython by the Rakata and their Flesh Raider soldiers. The Infinite Empire then retreated to the forest world of Ska Gora, where they conquered it and established their main command post. By the end of the initial year, the Je'daii had formed an alliance with the Settled Worlds' forces, placing Je'daii Master Rajivari in command of the combined forces. The Order, recalling Daegen Lok to lead them in battle as Lok had foreseen, also constructed and armed themselves with Forcesabers, the dark side weapons of the Rakata. Ultimately, the War concluded with a Je'daii victory; with the fall of Skal'nas, most of the Rakata turned against each other and fled, leaving behind a significant number of slaves.
