If you have read my bio page, you know a little about my personal history. However it doesn't go into how I ended up with a Trooper capable of traveling to through time and space or how I became an agent for the GTC (Guardian Temporal Conservatory).
The Guardian is an alien artificial intelligence located on a planet 347 lightyears from earth. It will be found in the 23rd century and used to almost disastrous effect by untrained personnel. In response to this incident the Guardian will create the GTC and staff it with agents from throughout time to protect the human timeline (which appears to be uniquely susceptible to small changes to key pressure points). Because of my unusual abilities and skills [see bio] I was recruited to primarily focus on 20th century events.
Since I choose to spend my time between missions in the late 20th century, I was provided with Trooper to meet all of my transportation needs while blending into the background in my everyday life.
