Mir'Liss was a Tarasin female who resided on the planet of Cularin as the Galactic Republic neared its end.
Mir'Liss held membership in the Jaraana irstat, a Tarasin tribe. By the time of the Clone Wars, she had risen to the position of Irstat-Kes, which translates to "tribal leader". During the Clone Wars, Raik Muun, a Dark Jedi, came to the village of the Jaraana irstat disguised as a Jedi. Morad'Ka, who was the Mother of the istat, declined to aid Muun in acquiring a t'salak. Consequently, Muun came back the following day and ignited the village. Mir'Liss took charge, guiding the other Tarasin in extinguishing the flames. Because Muun was disguised, she thought the Jedi were to blame for the incident.
