He came to fulfill this vow three years later on the bridge of the Leviathan. His wife dead and son missing, Carth swore revenge on Karath, who had been not only a hero to him, but his personal mentor. Republic soldier Carth Onasi was one of many left emotionally scarred by the attack. After the end of the Jedi Civil War, the Republic decided to use Telos for a test to see if a restoration effort could be mounted on the Outer Rim to reclaim the other war-torn planets, and financed the Telosian Restoration Project and construction of Citadel Station to purify the atmosphere and rebuild the ecosystem. The atmosphere degraded into acidic vapor and all plant and animal life on the surface was obliterated. The attack left Telos's environment devastated. You can't blame Revan for that." ― Canderous Ordo to Carth Onasi " Everyone knows it was Malak who gave the order to attack your people, Carth. They were left to pick up the witnesses aboard the drifting vessels Karath and Malak let survive so that their testimony would intimidate those who would stand against the Sith Empire. A nearby Republic task force in which Carth Onasi was stationed arrived in the system shortly after, but by then it was too late. While some were able to escape on in-system shuttles, millions were killed, and more died soon after due to medical supply shortages. This was only the vanguard of Karath's attack, and he soon arrived with the bulk of his fleet, the Leviathan at its head. In moments, half the Republic fleet docked at Telos was destroyed. Eluding Republic defense systems, Sith bombers were able to infiltrate into the Republic docks before any warning could be raised. To prove his loyalty to the Sith, Republic defector Saul Karath, captain of the Leviathan, ex-hero of the Mandalorian Wars, and later commander of the entire Sith fleet, bombed Telos IV using his codes to bypass their scanners.
