I use three names around the net for various things
Diamondflame is the name of a blue dragon in a book I read in middle school. It was my very first email address. It's been so long I don't remember anything about the book other then the main character could talk to animals and the dragons name.
Ryuu Tenshi as I was told, in Japanese, Ryuu means dragon and Tenshi means Angel, and for whatever reason I like going by Ryuu Tenshi the Dragon Angel.
Finally, Zero Ruin, as in nothing but ruin, which is something I came up with for a zombie character I created. It just kinda jumps at me as the perfect evil name.
