- "My son looks like me—and so does the future of the Sith."
- ―Ludo Kressh
Elcho Kressh, also known as Kressh the Younger, was the son of the Sith Lord Ludo Kressh. The senior Kressh began to fear for his son's safety as his rival, Naga Sadow, levied for the Sith Empire to wage the Great Hyperspace War against the Galactic Republic. To this end, Kressh designed a device to protect his young son from all harm, allowing him to only be touched should he will it. To further protect his prospect, Ludo had his son take refuge outside the Stygian Caldera on a remote Star system. From there, Elcho Kressh amassed a massive army made from dozens of systems worth of pirates and those who had a grudge against the Republic in secret. He used an array of bribes and deals allowing said groups to keep their autonomy but fight under his banner. On the eve of his invasion of the Republic to retrieve his and his father's honor, he died of a ruptured stomach after overindulging in alcohol.. Soon after, the massive force behind the movement dispersed as all of the deals were based on personal contracts and relationships Elcho himself engineered. Without Elcho, everything fell apart and the counter-attack never occurred.
Sometime during his self-exile, Elcho created a holocron of his teachings, which later was found by Sith Lord Mandragall and influenced Sith war-time strategy for generations to come during the New Sith Wars.
