According to the RP logic of the 13th Legion, I could say that I'm the son of the emporer, and therefore have some small claim on the throne, but I don't want it. Instead I chose to fly around space like a hobo and do odd-jobs to support my addiction to antiquing. Also I have laser eyes that will instantly melt the skull of anyone 12 kilometers away. I also like to sniff my own socks.
Much to my wife's disapproval, I like to sniff my own socks. How else would I know if it's sock changing day?
