Mercury, commonly known as Merc, was a former Runner who then operated as a Tracker; becoming well known for training some of the best Runners in the field. He acts as Faith's guide in Mirror's Edge. However, he was shot and killed when Faith returned to the lair after saving her sister.
While it is unknown exactly how Mercury became involved in the Runner business, he eventually became well known and favored as one of the industry’s best trainers. While returning to one of his hideouts, Mercury came across a sixteen year old girl (Faith) attempting to steal his possessions. Instead of reporting her, he offered her food, shelter and a job as a Runner.
Still in training, Mercury put Faith on a training run to trial the new ear pieces given to Mercury by Drake. Faith comes across Kreeg being pursued by a masked assailant and moves to help him, however as she tackles the assailant Kreeg’s Messenger Bag is opened and surveillance photos of Abraham Connors, Faith’s father, spill out. Unable to ignore the photos, even during her first official run, Faith visits her sister, Kate, who was in training to be a CPF Officer, in order to find out where their father was. Pointing her to Hoagy’s, Faith asks about her father appearing there but is lied to, only getting the truth when a worker there, Dusky, lets her look through the bar’s security tapes where upon she discovers her father meeting with old-acquaintance Austen Reynolds.
Looking for new leads Faith goes after Red, the photographer who took the surveillance photos, and, with Mercury’s help, is shown a house where she assumed was where her dad was. However, the person waiting for her was actually Austen Reynolds, who was waiting for Abraham to kill him as revenge for the death of Erika Connors, Faith’s mother , as the two were, at the time of the Libertas movement, having an affair due to Abraham’s neglect. Allowing her to leave with this information, Faith goes after Kreeg in order to find out who it was he was delivering the surveillance photos to. Infiltrating the given location she discovers the room belonging to Sebastian Silvine, head of Silvine Security, however, while she recognized the company logo from a chip created by her mother, she was unable to get anything else due to having tripped an alarm and needing to escape from Silvine Security officers.
After delivering a package to Robert Pope’s office Faith head over to Drake’s hideout to see if he could identify what the chip might be for. Leaving the chip with him, Faith receives a call from Dusky to meet her at Hoagy’s where she finally meets her father, Abraham Connors. However, Austen walks in on the reunion but is shot dead when Silvine Security officers enter the bar looking for the Connors. The pair managed to escape, however, and hid in Mercury’s Hideout where Faith asked him about the chip her mother had created.
Unable to help her, her father did tell her about a series of break-ins at the family home where it seemed that someone had been looking for something but hadn’t found what they were looking for. In an attempt to find this “something”, Faith breaks into their old family home, which was scheduled to be demolished. After receiving reports of someone breaking into the demolition site, Kate Connors deduces that it was Faith and confronts her at the house to get her out before the explosive blew. Managing to find a hidden letter from their mother, the sisters escape the site just in time.
Handing the letter over to Drake, he deduces that the chip and the notes in the envelope were for an advanced security camera to be used by Silvine Security and that that was the reason why the Silvine officers were chasing after them. Deciding that keeping the notes and chip was too dangerous, Faith opted to hand them over to Silvine however during the escape she is shot in the arm and forced to stay out of action until it healed.
Fresh from being out of action and fully healed, Faith spends some time retraining with Celeste, another Runner and friend, before being put back on active duty. During her first run however she encounters some overzealous Blues who, unprovoked, open fire on her and actively pursue her through the city until she manages to lose them by hitching a ride on a City Eye helicopter.
Laying low in Mercury’s hideout while Mercury asked around about why the Blues were being so aggressive, Faith overheard CPF radio chatter from her sister, Kate, who was reporting in to conduct a follow-up check with Robert Pope about a series of break-ins that occurred the week previous. However some time later further CPF chatter announced the reporting of gunshots from the area and Faith, concerned for her sister’s safety, rushed to the scene to discover her sister next to the body of Robert Pope. Certain that her sister was being set up for Pope’s murder, Faith took a piece of evidence from Pope’s desk (a slip of paper with the words ICARUS and to the highest), and escaped the Blue forces to begin an investigation into proving her innocence.
After discussing it with Mercury and Celeste, her first port of call was to question Jacknife, an ex-Runner, who might know something about the set-up. After chasing him down, Jacknife points Faith towards Pope’s head of security, Travis "Ropeburn" Burfield. Before going after Ropeburn, however, Faith gets in contact with Kate’s CPF superior, Lt. Miller, to get an update on Kate’s predicament.
Infiltrating the Z. Burfield Int. Shipping offices, Faith overhears Ropeburn discussing a meeting with an unknown individual over the phone, also mentioning Project Icarus and Kate and Faith. After informing Miller of this information, Faith goes to interrupt the meeting however she discovers Miller already there and assumes that he was the individual on the other end of the phone. Confronting Ropeburn to get answers, Faith manages to learn of another meeting place in the New Eden Mall before an assassin sniper shoots and kills Ropeburn.
Faith’s second attempt at overseeing this meeting met a similar end with her catching sight of the assassin sniper but running into, and escaping, an ambush set up by the Blues.
Fresh out of leads, Faith decides to look into Pirandello Kruger Security as she had seen their symbol on various papers throughout her investigation. Inside the building she stumbles upon a training facility created for the purpose of creating a specialized unit of Pursuit cops to target and take down the Runners network. Her infiltration eventually led to her boarding a shipping boat, belonging to Z. Burfield Int. Shipping, and capturing the assassin responsible for both Ropeburn’s and Pope’s murder; Celeste.
Her sister tried as guilty for Pope’s murder during her investigations, Faith, with help from some fellow Runners, interrupted the convoy that was transporting Kate to prison and freed her sister. However the Blues managed to track them back to Mercury’s lair; resulting in Kate’s recapture and Mercury’s death.
In his last moments, he was able to tell Faith where Kate was taken: The Shard
- Derived from Roman mythology, Mercury (associated with the Greek god, Hermes) was the god of trade, profit and commerce, and popularly known as the messenger of the gods.
- According to the screen accessed by Faith on Pirandello Kruger, Mercury's last known residence was in Wilshire Boulevard, Los Angeles.
- Mercury does have a fully rigged and textured 3D model, though he only appears on cutscenes in his animated form, and in gameplay as a voice.
- Mercury is almost certain to return in Mirrors Edge 2, as he was a key part of Faiths childhood and training.
