Talduk Sik was a Grey Orion slave who lived circa 9050 BCE (reference stardate -110/50). He was part of a technical working group about to leave the Rigel system when he was detained by the Rigellians. The first Orion they'd studied, he was carefully interviewed and questioned over the course of a few days.

His experience became an almost mystical one for the Orions, particularly the Greys. Some would think of the Rigellians as their 'Makers' into modern times, though the Rigellians themselves felt forebodings about them.

As a Grey Orion, Klendal's role would likely have been erased from Orion history or rewritten in some way during the Reverse. (FASA RPG module: The Orions: Book of Deep Knowledge)
