The Holwuff were a sentient species in the galaxy. One Holwuff, Senator Rogwa Wodrata, supported the Confederacy of Independent Systems during the Separatist Crisis, attending a summit on Geonosis where the Executive Separatist Council pledged loyalty to Count Dooku just before the beginning of the Clone Wars.
