Kolyat Krios

=== Early Life ===
While Kolyat was born in a loving relationship, he rarely saw his father due to Thane's freelance assassin profession. His mother Irikah did her best to raise him alone as Thane's jobs took him further and further from home. While Thane loved his son dearly- believing him a gift from the drell goddess of motherhood Arashu, his work was a constant distraction. Kolyat often felt ignored and/or unloved by Thane.
Thane's enemies discovered the existence of his family when the assassin was gone from home. The Krios household was assailed and while Kolyat was able to successfully hide, Irikah was killed. This utterly broke his father.

In 2185, Kolyat accidently received his inheritance early and discovered the true nature of his father's work. Using some of his father's old contacts he took a hit job on turian politician named Joram Talid. Commander Shepard and Thane manage to stop the assassination attempt. While Kolyat was furious at their interference, and overwhelmed with bitterness at his father's absence and subsequent appearance, he managed to listen to Thane explain why his mother was killed, and why he couldn't bring himself to come back. Thane told him that while he had used his skills to take many bad things out of the world, Kolyat was the only good thing he had ever added to it.
Commander Shepard managed to convince Captain Bailey not allow the case to go to trial, and Thane promised to keep in touch with Kolyat to begin to make up for his mistakes.
=== Mass Effect 3 ===
After Thane survived the mission beyond the Omega 4 Relay he returned to Kolyat, determined to spend what little time he had left beside his son. Kolyat also spent most of the previous year with some drell priests, learning from them. When the Reapers hit Earth, both drell were on board the Citadel with Thane receiving treatment at Huerta Memorial Hospital for his Kepral's Syndrome. After saving Councilor Valern from Cerberus assassin Kai Leng, Thane was mortally wounded. Kolyat and Shepard attended Thane at his deathbed, and per his father's request Kolyat says a prayer for Shepard.
When the Normandy docked at the Citadel for repairs late in the Reaper war, Shepard hosted a memorial service for Thane at her apartment per Kolyat's request. When it comes to his turn to speak, Kolyat said that while he had previously thought his father had been going soft, but with recent events in mind maybe his father had figured things out after all. After the service, Kolyat approached Councilor Valern of the possibility of funding some salarian biologists who have some promising interest in Kepral's Syndrome. He also passed along three video messages Thane had tried to send to Shepard while she had been incarcerated in the wake of the Alpha Relay destruction. 
== Every One That Asketh ==
Kolyat survived the Reaper war; in the wake of the destruction and suffering, Kolyat appears to be traveling the galaxy providing prayers and comfort to the dying. In 2188, Shepard sees a vision of him attending to a dying child as her own condition worsened though she was unable to distinguish his identity. After having some kind of experience where she was speaking to her dead squadmates, she awakens to find Kolyat at her bedside praying for her. At her confusion, he tells her that he is not his father and “I knew this was where I needed to be. I go where Kalahira bids me.”
