Purely by chance...
There is no reason why I chose Unkempt, except that it sounded cool at the time. And with the all the shortenings of it (UK, Kempty, Unk), and how they can be used, has only proven to me that it was the absolute right choice. You can say that about many of my decisions involving the fandom. Made on the fly, but turns out to be the best thing I could've chosen.
Now, Unkempt's "true" name, Aaron Trundiel, is a different story. Trundiel is the family name I created from the word turndial, and it's shared as a last name of a royal family throughout one of my stories. Unkempt is the main character of the story and is the last of the line. How I got Aaron is because my alias is "A. Furry Mcfur". The A had to stand for something, and I plan on using Alex in real life, hence, Aaron.
