Koeryn (The name I use practically everywhere) was a name I came up with when I was like... 13? I was just sitting on my ass when it hit me, "Corin is a cool name. But not spelled that way. Needs a different spelling... K-o-e-r-y-n. That sounds the same... I think... Yeah, it does. Okay. Awesome."
And that's mah name. On YouTube, deviantART, PSN, and practically everywhere else I go on the internets.
For awhile I was T'Klesh Learnu but I don't remember where that one came from.
My old steam account was NoMoulah, becuase... Well, I had no moulah. =D It's my little brother's Counter-Striking account now though... -shakes head-
There's a couple of places I'm also known as GreenEyes or GreenEyesArtist, which is the... well, not name so much as descriptor of the main character in the novel I'm writing of the same name.
