Mercury

Mercury is a secondary character in Heaven Will Be Mine, and is affiliated with Celestial Mechanics. He is assigned by Iapetus to advise Saturn after her escape with the Interloper Prototype String of Pearls.

Personality
Mercury is serious and intelligent, and is loyal to Celestial Mechanics despite Iapetus's treatment of Saturn. Mercury usually questions, is suspicious, and suffers the consequences of Saturn's actions and motives, but continues to associate with her regardless, although this is partially out of obligation. Regardless, Mercury still can't seem to stay mad at Saturn for long.

Background
Mercury is, or was at one point, a friend of Saturn's, and shares in Saturn's hatred towards Iapetus, because of both his failures as a leader, and the abuse he and Saturn suffered from him. He made an initial attempt to stop Saturn from stealing the String of Pearls, but was ultimately thwarted by Saturn's hacking-hijacking abilities. Following this, Iapetus decided to simply allow Saturn to prove herself a worthy pilot of the String of Pearls and assigned Mercury to Saturn as an advisor.

It is implied that Mercury is transgender. In a conversation in one of the email files, titled "Pilot Candidate 007 Interviews," he is pressured to reveal that he takes testosterone, before telling the Celestial Mechanics employee to "stop treating [him] like a girl, and [he'll] know [they've] really got it."

From some time before the events of Heaven Will Be Mine, Mercury has been in a loving relationship with Captain Ganymede (Celestial Mechanics).

Trivia

 * In Iapetus's email to Saturn regarding her "Apparent Promotion," he reassigns Mercury to Saturn "since he apparently already doesn't have a say in the matter. How nostalgic," which likely means that Mercury has consistently had to deal with Saturn's mischief before.
