Little is known about the Shistavanen beast known as Skole, or even if that is his real name. Records indicate that his first known sighting was on Uvena Prime, during an incident in which a laboratory controlled by the Sith was completely destroyed, and it is theorized that he was involved in biological or Force experiments there. Further reports available from Ruusan indicate the presence of Skole on that planet on several occasions, during which times he acted with uncontrollable aggression, attacking with no provocation or apparent reason other than he seems to enjoy hurting others.
