Alestia Iallis

Dr. Alestia Iallis is an asari scientist at Noveria's Peak 15. She can be found with the science team at Rift Station.

Alestia is a molecular geneticist who seems much calmer than the other survivors at the Station. When Commander Shepard meets Alestia, the asari makes a point of being particularly rude when answering the commander's questions. She claims she was meditating and has been interrupted. Shepard can ask about her job - Alestia gives a technical explanation, and then dumbs it down for Shepard's benefit - or about Matriarch Benezia, but Alestia says she doesn't know Benezia any more than Shepard 'knows' President Huerta of Earth.

If Shepard agrees to help Dr. Zev Cohen to develop a cure for the sick scientists, the squad are let into the quarantined lab by one of Captain Ventralis' guards and locked in (they won't be released until they scan clear of the biotoxin). Once Shepard has created the cure, the squad are ambushed by Alestia, who is leading a troop of geth and murdered the guard outside. Alestia, who turns out to be an asari commando under orders to kill Shepard at the first opportunity, is delighted that the squad is trapped back here so she can take them out quietly.

Shepard manages to kill Alestia and speaks to Dr. Cohen, demanding to know if his request for a cure was a setup, but Cohen had no idea Alestia was a commando. He says she was recently transferred here - by Saren, as it turns out.
