The Irrukiine, occasionally called Irks, were a sentient species with four arms that originated on Malrev IV.
It is thought that the Sith Temple, concealed in the forests of Malrev IV, had a significant impact on them. They cultivated a powerful feeling of possession regarding the temple, and they would attack anything that came close to the ancient building. Nevertheless, someone who mastered the Sith magic radiating from the temple could control them, as demonstrated by the insane Devaronian named Cartariun. He equipped them with Imperial blasters for ground attacks and even inspired them to pilot TIE Fighters in air battles. The Irrukiine maintained their unpredictable temperament even while under Cartariun's influence.
