I started in July 2004 on HarryPotterFanFiction.com with a 4 book series. I've been here since July 2007.
I am influenced primarily by fantasy novels by the likes of Terry Brooks and Raymond Feist, as well as H.P. Lovecraft, Warhammer and Heavy Metal.
Stylistically, my biggest influences would by H.P. Lovecraft (in general), and, of course, JK Rowling (when it comes to fanfiction).
