Gruenak

Captive Gruenaks

Gruenaks were a race of Thra with a reputation for being mechanically-minded and strong. They were almost completely exterminated by the Skeksis, though two survivors were later captured by Sifan mariners and sold to skekSil, who handed them to skekTek so that they could assist him in repairing the essence-draining machine. However, following their attempt to escape, the Scientist killed both of them by throwing one down the Castle shaft and bludgeoning the other to death.

Gruenak physiology was later combined to that of the Arathim Silk Spitter to create the first Garthim.
