LemonTree was one of Vincent van Eylen's characters (VinnieTheDark was his IRC nick, and one of his most prominent characters was Vinnie, in Darka; I don't recall where LemonTree was based). He started that page way back in the day—on the TikiWiki, as I recall—and it eventually became the go-to place for fame theories. And remains so even today, long after Vinnie left the game and most people don't remember or never knew him.
Thalmarkin, founded the short-lived Lemundia.
I didn't know he was gone... How long ago did he quit?
