Utapau

Utapau is a sinkhole-covered world in the Force Galaxy, home to two native races - the Pau'ans and the Utai, known collectively as the Utapauns. It was a stronghold world for the CIS during the Clone War and one of General Grievous's last remaining rally points for the Seperatist leaders, the next being Mustafar. The Battle of Utapau took place here which saw the fall of Grievous and also the apparent death of Obi-Wan Kenobi during the execution of Order 66.
