On April 7, 2102, Mark Sarang received a classified message from the supervisory board of Carthage Industries, complimenting Saran's success in making the WAU a station-wide presence. The letter suggested that Sarang explore and understand the WAU by any means necessary, and insisted that Johan Ross being able to "steer and study" the WAU from Alpha without interference was contingent on accomplishing that suggestion. The letter allowed Sarang to contact Julia Dahl at Omicron to "forcefully eliminate any opposition," in an emergency.
Mark Sarang, Johan Ross, and Julia Dahl were the only three people at PATHOS-II working directly for Carthage, they kept this information secret.
On July 9, 2103, Sarang was interviewed by Catherine Chun regarding his expectations toward the ARK-project. Sarang states his belief that "we can go on living through the reality of continuity."
During this period, Sarang was primarily focused on developing his belief on continuity, but Sarang does in fact notice the unusual mutations caused by the leaking structure gel in and around Theta. He took pictures of these mutations and they can be found in his room at Theta. On which, scribblings reveal Sarang's inability to explain why the WAU was organizing these mutations.
On July 12, 2103, during his brain scan for the ARK-project, Sarang committed suicide by chewing gum containing cyanide salts. He left a recording and notes revealing his purpose: to ensure that his virtual self, living in the ARK, was the only remnant of his consciousness. He viewed human consciousness as an entity that transcends a physical body.
His ideas caused other PATHOS-II personnel to commit suicide during or shortly after the brain scanning process, which led John Strohmeier to prematurely end the ARK-project.
While venturing through Theta facility, Simon Jarrett can access Sarang's dormitory where he can find computer logs, voice recordings and notes, mostly about his ideas over "continuity."
- His surname, Sarang, which means Love in Korean, is a reference to the Korean-American Moon harvesting base Station Sarang from the movie Moon by Duncan Jones, a film which deals with some similar subjects as SOMA.
