It's a bit of a long, convoluted story, but since you asked so nicely...
Several years ago, a few months before the release of Final Fantasy XIII, GameTrailers released a multipart retropspective of the entire FF series - it's really good too, check it out if you haven't seen it and you can find it in the incomprehensible mess that is GT's search system. The final episode of that retrospective was a review of the major recurring themes Final Fantasy stories have, and as the video put it, "how one could build a Final Fantasy from scratch". I thought it was a nice though experiment, and I had to fill a sketchbook with ideas and art for one of my college classes, so I wrote a small 60-something page design document for a Final Fantasy fan project, detailing the world concepts, lore, characters, plot, combat system, etc. I poured dozens of hours in that project and even though nothing will likely ever come out of it, it's very dear to me (and I got a prefect grade for it in school, too). Since then, whenever I can name a video game character, I name them after one of the playable characters of my FF project.
Fast forward to 2013, when Final Fantasy XIV comes out on PS3. Even though you can play all classes with a single character, I didn't know how long I'd be stuck with my starting class, and since the game allowed it for the first month, I created one character for each available class, naming each after the character who had the most similar class in my project, and used the character creation tool to recreate the face I drew for them in concept art. I had Damian Callis the Conjurer, Ophelia Aquino the Thaumaturge, Dirge Novak the Gladiator, Weylin Drako the Lancer, Maïte Madec the Arcanist, Karima Naifeh the Pugilist, Tanig Hinault the Archer and Leandro Roxas the Marauder. (Only eight classes meant I had to leave off the two remaining characters, Cassandra Sideris and Nadine Naifeh. Sadface.) I played each to level five and then picked my main character, which ended up being Dirge. Switching to the entry level subscription on month two meant I had to delete the other characters. I wish I had thought to take screenshots...
Then, at the beginning of last year, LoadingReadyRun started doing a lot of Twitch streaming and I had to create an account to interact with the chat. I was getting pretty tired of my old username (Kakulukia, a reference to Prince of Persia: The Sands of Time), since I've hated Ubisoft for years and my username tied me to them, so I took the opportunity to change my online identity, and I thought Dirge was perfect. It doesn't really sound like a person's name even though it is, and it has deep personal meaning to me. So I changed my username on every site that allowed me, made new accounts for those that didn't - except for Steam and PSN, because Valve and Sony apparently hate us all - and I've been happier for it.
