Chusuk was the fourth planet in the Theta Shalish system, also known as the "Music Planet". It was renowned as a manufacturing source of premium musical instruments, and to a lesser extent for its resident humans, who practised the Navachristianity religion. It was also the home of Varota. In 173 BG, the planet was assaulted by Tlulaxa slavers. They left a cymek body there, so as to be believed as a Thinking Machine attack.
