Korsk

Korsks were creatures used by the sentient Yuuzhan Vong species to scrub. When the Yuuzhan Vong shaper Nen Yim was younger, sometime before the Yuuzhan Vong War, in which the extragalactic Yuuzhan Vong invaded a galaxy other than their own, she and a pair of crèche-mates, P'loh and Zhul, put a korsk in a communal eating area where it proceeded to eat all of the i'fii foodstuff. In 29 ABY during the war, Yim discovered that the Jedi Knight Tahiri Veila shared her memories, including the korsk incident. This led Yim to realize that her own personality had been implanted in Veila's mind during an attempt to make Veila believe that she was a Yuuzhan Vong via shaping, a form of Yuuzhan Vong bioengineering.
