Sarissa Theris

Sarissa Theris was an ex-Asari commando, known for her teachings in asari ways. She becomes the Asari Pathfinder after leaving her predecessor, Matriarch Ishara, to die at the hands of the Kett. Pathfinder Ryder has the choice of revealing her to the other Asari on board Ark Leusinia, with her being deposed, and Vaderia Damali taking her place as the new Pathfinder.

Not much is known about her, except for the fact that she has incredibly powerful biotics, even for an asari.
