My real name is David, named for King David. I'm quite fond of it.
Tyloric is a role playing name I used more than ten years ago, the name of a character that I eventually killed off.
Before Tyloric actually stuck as my username, I had a few others that were long term:
Demonstar, named for my favorite video game at the time. (2002-2006ish).
Ikon, was just a name I came up with because I had become bored with Demonstar. I always pronounced it "Iken", because in some languages the o is perfectly capable of making that sound, but everyone always said "Icon", so it was ruined for me. (2006-2007)
Secksy was a name that stuck because my main in Guild Wars was (and still is) "The Secksy Monk" (wiki link in my sig <3). When I joined my (now ex) guild, I made my username St. Secksy to avoid confusion between an alt handle and and an alt char name. It's weird, because it just became totally normal to say amongst us. No one ever thought it was, and still don't, think it's weird. I am Secksy to them. <3 (2008-present, only within a select group of people)
Tyloric is what happened when I grew tired of Ikon, and I remembered that roleplay from so many years ago. I really like it, and will probably stick with it for a while. I mean, come on, it's still a great roleplaying name. Tyloric Trubane (formally Tyloric Mizanithe), at your service. (2008-present)
And that, ladies and sexier ladies, is a brief history of me.
