"Your species needs to learn it's place, Shepard."
Saren Arterius, born 2139, is the longest serving turian member of the Spectres, the elite operatives answering directly to the Citadel Council. For 24 years, he has been an agent of the Council's will, a zealous defender of galactic stability in the unsettled border region of the Skylillian Verge.
Official records of Spectres are sealed, but it is known that Saren followed turian tradition and entered the military at the age of 15. In 2155 he was promoted to active service after only a year of training, though it is unclear whether his unit was involved in any of the battles against human forces during the First Contact War of 2157.
In 2159 he became the youngest turian ever accepted into the Spectres. Intelligent, cunning and capable, Saren quickly developed a reputation for ruthless efficiency. Although there were a number of unsettling rumors concerning the brutality of his methods, there was no denying his results.
In recent years, Saren has become an outspoken opponent of human expansion. Like many other non-humans, he believes the Systems Alliance has become overly aggressive in its efforts to establish the people of Earth as a dominant species in Citadel space. Historically, species take centuries to accomplish what humanity had achieved in less than one, and there are several species that have a "lower" standing on the Citadel compared to humanity, despite having been part of the Citadel community longer.
His specieism is speculated to have originated in the First Contact War, when the turians attacked Shanxi. In the novel, Mass Effect: Revelation, Anita Goyle informs David Anderson that Saren lost a brother in the war and has disliked humanity ever since. After their abortive mission together, Saren retained a particular dislike of Captain Anderson.
Saren has little regard for life. He does not see saving lives as a priority unless the Council deems it necessary, or if there is information to be gathered. He remains the Council's top agent despite his records: Saren may be ruthless and calculating, but he gets results.
