So here's my story,
I wasn't always a Tajaran, in fact I used to be human. I started my shift as a civilian. I went to the Head of Personnel. Hoping to get a job that I wasn't entirely qualified for but was still willing to learn. At the time Security was my interest, but of course got denied. Head of Security wasn't taking new officers. I guess he wanted ones straight off the shuttle. So a little while after the shift went by and me going around Maintenance and general quarters, I head to security. I wanted to get a feel for what was going on around security and learn from their actions, bear in mind I was somewhat new to Nano Trasen at the time. I walk in to the Security lobby to the Head of Security in his armored coat standing talking to a couple officers. A few minutes later a suspicious looking person walks into the Security lobby and is standing a little too close to the Head of Security and the other officers. He pulls something out and I could hear more than see either the Head of Security and the security officer try to disarm him. The suspicious person takes a few steps back, the Head of Security turns to go into the Secure area, and I, being a stupid person, tried to jump in and help. I attempted to disarm him, stood right in the way of the Head of Security and the guy ... and we blew up. The Head of Security makes it with moderate injuries, the Security officer and I are worse. I remember waking up in the OR gasping for breath, no matter what they did, my lungs had failed. So they did the next best thing. They transplanted my brain into a Tajaran, my body was biomassed, and I became a different species.
