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

Mass Effect

Captain Ventralis mentions Han if Commander Shepard asks what happened in the hot labs; Ventralis explains that Han was the only survivor of the rachni attack and "he ain't all there any more". Dr. Palon asks Shepard to be considerate to Han because he has been through a terrible experience.

Han is severely traumatised by his experience and answers Shepard's questions monotonously. He tells Shepard's squad that he knows they are there for the rachni, surprising them due to the rachni's believed extinction. Han Olar explains that Binary Helix found an ancient egg, aboard a derelict vessel drifting in space, from which a Rachni Queen hatched. In retrospect, he believes it might have been a mistake. Two other scientists across the room tell him to shut up and stop talking about confidential information: "If you're going to be crazy, be the quiet kind!" However, Han no longer has an interest in keeping Binary Helix's secrets, stating that he has no control over who lives or who dies.

When Shepard asks how he survived the hot labs, Han answers "I killed her," much to the shock of the squad. He explains that he and a co-worker, a female scientist named Dr. Zhonmua, were going to lunch when the alarms went off and the rachni escaped containment. Han managed to get to the tram tunnels, reach the train and close the door behind him; he describes the gory death of his colleague without emotion.

If Shepard makes the biotoxin cure and is ambushed by Alestia Iallis, Han points the Commander to the maintenance area where the geth came from, and suggests they ask Dr. Zev Cohen for a pass in order to enter there.

If the hot labs was neutron purged first and Shepard descends to the scientists' quarters en route to the Secure Lab, Han is seen being threatened by Matriarch Benezia's forces and he asks the asari commando pointing a gun at him if he'll get a "you know too much speech". After the hostiles' deaths, Han tells the Commander that he's the only one left. Having become a sole survivor twice in a relatively short period of time, he muses Shepard should stay away from him. Han thinks Binary Helix wants to bury their rachni mistake and everyone involved: they sent Benezia to deal with the problem, and Han claims she ordered Ventralis to lure Shepard to the hot labs expecting the rachni to kill the Spectre's team. He doesn't care anymore what happens next, only telling the Commander he's getting off the mountain.

Mass Effect 2

If Shepard met Han on Noveria in 2183, he sends Shepard a message, entitled "Therapy":

From: Olar, Han


They say you're alive. That you cheated death. That sending you this isn't just a pointless exercise as part of my therapy. They say a lot of things.

I'm still alive. She still isn't. I hear you killed Benezia. Nicely done. Another woman I helped kill, if my information did any good.

They want me to thank you. The rachni would have killed us all had you not shown up.

It would have been right.

Why me and not her? Why did you show up then and not before?

They think that they can fix me.

But maybe you're not really back. Maybe I died. Maybe I didn't close that door in time. Maybe I held it open to give her a chance, and the rachni ripped my suit open, and I died of exposure there on Peak 15. Maybe I'm a martyr, and this is an ugly hallucination before a glorious afterlife.

But if I'm not, then thank you.
