Han Olar

Han Olar is a volus at Peak 15's Rift Station on Noveria. He can be found in the scientists' quarters.

Captain Ventralis mentions Han if Commander Shepard asks what happened in the hot labs. Ventralis asks Shepard to go easy on the volus - Han is the only survivor of the Rachni attack and "he ain't all there any more".

Han is severely traumatised by his experience and answers Shepard's questions in a quiet monotone. He tells Shepard's squad he knows they're here for the Rachni, which surprises them because the Rachni are extinct. Han Olar explains about the egg that Binary Helix found, saying that they brought the Rachni back from the dead: in retrospect, it might have been a mistake. Two other scientists across the room tell him to shut up: "If you're going to be crazy, be the quiet kind!"

When Shepard asks how he survived the hot labs, Han answers "I killed her," much to the shock of the squad. He and a co-worker, a female scientist, were going to lunch when the alarms went off and the Rachni escaped containment. Han managed to get to the tram tunnels, reached the train and closed the door behind him. His co-worker banged on the glass before the Rachni reached her. He describes the gory death of his colleague without emotion.

If Shepard makes the biotoxin cure and is ambushed by Alestia Iallis, Han can point the commander in the direction the geth came from (the maintenance area) and suggest they ask Dr. Zev Cohen for a pass to sneak back there.
