Before he became the Power-Armored hero Solar Aegis, Drake Fitzgerald was once one of NASA's astronauts - a pioneer bound for the final frontier with a desire to explore the solar system and possibly beyond. For all his training and preparations, however, what Drake found on his mission to the Moon would prove to be beyond his wildest expectations.

Shortly after the landing pod touched down on the lunar surface, Drake and his crewmates found a moonbase of unknown origin just several yards away from the landing zone. His curiosity getting the better of him, Drake proceeded to investigate the structure. After a brief examination, it became clear that the moonbase had been abandoned long ago - and that it was certainly not of human origin. He pressed onward, searching for answers to the questions that began to arise in his mind.

Drake eventually found a room filled with various high-tech machinery and tools as well as several pieces of armor strewn about. As he stood in the center of the room, looking around, Drake suddenly found himself floating just above the floor as the machinery sprang to life. By the time his mind could process what was happening, a swarm of nanites had already begun rapidly deconstructing his space suit, replacing it with a full set of powered armor. Once the process was complete, Drake just stood there for several moments, examining his new armor in equal measures of shock and wonder.

His thoughts were promptly interrupted by an unfamiliar female voice speaking through his new helmet; this voice, Drake soon learned, was Katah, his new armor's "Living Intelligence" (or "L.I.").

As the "Living Intelligence" residing within Drake's armor, Katah is responsible for managing most of the armor's systems, be they permanent systems or temporary adaptations. Due to having been in stasis for an extensive length of time, her memory of events prior to her awakening is foggy at best - a fact that has not been helped much by the deterioration of the lunar base's database and records.

She is also capable of projecting an intangible hologram of herself next to Drake, should she feel so inclined to do so.
