Yitabo

Yitabo was a planet.

History
During the Galactic Civil War, Imperial slavers captured Wookiees as slaves on this planet. A unit of Churhee's Riflemen tracked the Imperials, looking for an opportunity to free the slaves. While doing so, one of their scouts, Gunman, was captured by the slavers and placed on a slave collar. The rest of his unit later managed to free him and the rest of the slaves. The then Wookiees took their revenge against the slavers in a brutal manner.

Behind the scenes
Given that Churhee's Riflemen saw action on this planet it may be within the Parmel or Sarin Sectors where they were based.
