Christine is the latest in a line of adventurers in the Trelane family, most of whom have met a violent end. She joined Stormwatch as an activator in the mid-late 80s, and she met Jackson King during their shared time in the Stormwatch Academy. He was a close friend of Academy head John Windsor, a somewhat conservative man, whose opinions and attitudes towards Stormwatch and the seedling program were in direct opposition to the crowd that Christine ran with. This friction lead to a brief and passionate relationship between herself and King. They split up shortly before they left the academy, and didn't see each other until the end of King's first Stormwatch Tour of Duty.
Trelane served as a general agent for Skywatch, investigating seedlings and occasionally participating in field missions. She rose through the ranks and was eventually named second in command of Stormwatch, and replaced Henry Bendix as Weatherman following his dismissal. Her tenure as Weatherman was the one of the darkest points of Stormwatch's history. Batallion was killed in action while fighting Maul from the WildCATS(who had been brainwashed and mutated by the Daemonite Lord Defile), and when she named Diva as the new Commander of Stormwatch One, Cannon quit the team in anger. Two new members, Pagan and Undertow were activated as replacments, just in time for the Wildstorm Rising incident, where Defile brainwashed Stormwatch Prime, and the threat was so great that the UN Security Council released the Warguard, who fleed from the battlezone and set up in the UN moonbase, killing the crew there. During the ensuing battle between Stormwatch and the Warguard, the team was decimated, with Diva being killed, Strafe(Malcom King) turning to the Warguard's side, Hellstrike dispersed over the earth's atmosphere, Undertow fell into a coma following serious injuries, and Skywatch itself was crashed into the nevada desert. It was only due to the return from the dead of Batallion(it turned out he faked his death and had been training for this moment in the six months he was away) and Henry Bendix as Weatherman that saved the team from total destruction.
Christine took her position as second in command again following these events, and took over training of a number of new Stormwatch officers, the final graduates of the academy program. During Henry Bendix's reformation of Stormwatch following the Fire from Heaven incident, she was returned to the field, investigating new seedlings again It was during this time, that she and King rekindled their relationship. Following the revelation that Bendix was using Stormwatch to further his own agenda, and Jackson King's promotion to the position, she was moved back to Skywatch staff and second in command position, her duties consisted mostly of research and support tasks.
Following the second fall of Skywatch, Christine and Jackson were moved to the UN building in New York, where they headed up the Bureau of Superhuman Affairs, providing what little intellignece they could to the UN security council. They assisted the Authority for a little more than year, towards the end of which, they attended the fateful party on the carrier. There Christine ran into Flint, who she hadn't seen since the disbanding of Stormwatch. While sharing a bath, Christine revealed that she hadn't has a period for 18 months, before having a kind of siesure that changed into a burst of energy. She manifestd herself before King, telling him they had work to do, and then they returned to New Your to make plans. Christine and Jackson married in the following months, and gathered around them an army. Now, as the Monarchy's second in command, she uses her powers to seek out places where people have gone wrong, and fix them.
