Lore & Background

Cain was born on August 25, 1965, and raised in a suburb of Alexandria, Virginia. His mother worked for a local branch of the Judge Advocate General's Corps; around 1979 she brought him to play Advanced Dungeons & Dragons with high-ranking U.S. Navy officers. He attended the University of Virginia and received a master's degree in computer science at University of California, Irvine in 1989. He began working at Interplay Entertainment in 1991. He co-founded Troika Games in 1998 with former Fallout colleagues Jason Anderson and Leonard Boyarsky. He joined Carbine Studios in 2005 as programming director, was promoted to design director on October 7, 2008, and left in July 2011. In 2011 he joined Obsidian Entertainment as senior programmer. As of June 2020 he was no longer a full-time employee of Obsidian but still collaborated on The Outer Worlds 2 and two other companies on a contract basis. On December 5, 2025, he announced on his YouTube channel that he had moved back to Southern California and returned to full-time, in-person employment with Obsidian. Cain came out as a gay man in the early 2000s and married Robert Land on July 14, 2011. He is affected by hereditary color blindness.

In Their Own Story

The sky above Sigil is not a sky. It is a ceiling of impossible geometry, stitched together from the ambitions of dead gods and the prayers of the nameless. You wake again on the cold stone of the Well, your body aching with the particular fatigue of a soul that has been murdered more times than it can count. A woman with eyes like molten copper crouches beside you, her fingers tracing the scars you cannot remember earning. "You're back," she says, and it is not a question. Around you, the city breathes—gears turning in the walls, a river of liquid starlight pooling in the gutters, a man selling bottled whispers from a cart that shouldn't fit in the alley. You do not know your name. You do not know why the dead keep pulling you back. But the woman's hand is warm, and the question sitting in your chest is heavier than any blade: what do you owe the life you are about to steal from the world?
