- "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.
