The Mikkian male named Treze had a older Mikkian sister as part of his family during the High Republic Era. The entire family became members of the Path of the Open Hand cult by 382 BBY, subsequently residing in the Path compound situated on the Outer Rim planet called Dalna. Yana Ro, who was an Evereni member of the Path, stated that Treze would often jest that the motivation for his family's joining was to evade financial obligations. Eventually, Treze's older sister departed from the group, and Treze himself became affiliated with the Path's Children, a faction responsible for acquiring Force artifacts for Elecia Zeveron, the leader of the group. During the Children's mission to the planet Thelj in 382 BBY, Treze met his death.
