In early September 2012, Kyle Arvida developed a type of phase shift specifically engineered to keep his entire SG base from being affected by its surroundings. Prior to the darkness overtaking Paragon City (which he constantly monitors, but cannot see either form or movement from since), he and 11 of his most elite generals took refuge in the base with enough resources to last indefinitely if necessary. The majority of his time is spent sleeping, reading, working out, doing maintenance on the base, and tinkering in the SG labs to invent new and more effective armor, enhancements, and weapons tech for his eventual return to Paragon. Of course, there are the occasional wild parties that end up with beer bottles, wine glasses, broken furniture, IOs, and random salvage strewn all over the base, but it's hard for heroes to be cramped into 5,000 square feet when they're used to the world being their playground.
Every day, Kyle gets up, stretches, walks to his window, and peers into the blackness, hoping to finally see something...a building, a person, or any recognizable form. But so far, nothing. Still, he is optimistic. He has a feeling, deep down, hard to identify or explain. But he somehow senses that the terrible events that led to this involuntary confinement - this stasis - are somehow changing, even if he can't see any direct evidence of it yet. But the feeling is like knowing how to fly - when you know, you can just do it, easier than explaining it.
Kyle used to be tired. He faced conflict after conflict; battle after battle over years, and then decades. Injuries never quite healed and pain never seemed to fade. But he was happy to answer the call. There was always work to be done to protect Paragon City. But now, things are different. 19 months later, he is fully rested, stronger than he's ever been, and mentally, he's completely at peace. The brief respite that never seemed to come finally came. And now, he's ready for battle. So when Paragon finally beckons to him that she is ready, he will respond happily:
