Sloan was born on Earth near Pretoria, South Africa. Sloan graduated from Starfleet Academy, but did not study at the main campus in San Francisco, instead studying on an Academy satellite campus. Under "career goals" on his academy application, Sloan wrote that he one day wished to be the head of Starfleet Intelligence.
In 2360, Sloan met with head of Starfleet Intelligence, Admiral Nyota Uhura. Upon noting Sloan's career goal, Uhura privately vowed with amusement that Sloan would never be head of S.I. while she lived. (TLE novel: Catalyst of Sorrows)
In 2371, Sloan assigned Ensign Roberta Luke to the USS Voyager to gather intelligence about the Maquis before that vessel was lost in the Delta Quadrant. The ensign had seemed highly attracted to Sloan, but the director spurned her advances. (VOY - Section 31 novel: Shadow)
- In Shadow, Ensign Luke referred to Sloan as "director", implying a ranking system within Section 31. It is currently unknown which other senior operatives hold that rank, but such operatives as L'Haan and Vasily Zeitsev would seem to be possible "directors".
In 2374, Sloan intercepted a stolen shipment of latinum from a Hamexi named Mexh Brixhta. The latinum itself was unimportant to Sloan and Section 31, but the vials that contained the latinum also contained scientific data and formulae that Section 31 needed to perfect their virus designed to eliminate the shape-shifting Founders. (DS9 novel: Hollow Men)
Later that year, Sloan attempted to recruit Dr. Julian Bashir into the agency. Bashir refused, but Sloan still considered Bashir to be an asset, and later recuited him for an assignment on Romulus. (DS9 episodes: "Inquisition", "Inter Arma Enim Silent Leges")
Sloan died by his own hand in 2375, after being lured to Deep Space 9 by Bashir, who needed information from Sloan in order to develop a cure for the disease that was wiping out the Founders and created by Section 31. Bashir and Miles O'Brien managed to capture Sloan and were going to interrogate him using a Romulan mind-probe device, but Sloan activated an implant in his brain, choosing suicide over allowing the secrets within his mind to be revealed to Bashir. (DS9 episode: "Extreme Measures")
Given his unpleasant memories of manipulation and subterfuge involving Sloan, Bashir was initially somewhat disturbed to discover that the Luther Sloan of the mirror universe was a member of the Terran Rebellion when Lieutenant Nog established communication between Deep Space 9 and Terok Nor in January 2377. However, as Bashir was aware that his own counterpart had been "something of a brute, a hot-tempered fighter with quite a vicious streak," he conceded that Sloan could have been equally different from his primary universe counterpart.
