I've been creating a world for Nikki's Ice Queen persona. I'm still in early stages, but I've been working on lore and other background information for his realm. It details the birth of the Kingdom of Feysaili, Nikki's life as crown prince, the destruction of his dynasty, and his restoration to the throne as Queen Regnant. It's been a lot of fun creating this. You can find the information here: http://www.furaffinity.net/view/13624360/

I also thought it would be fun if I started an ask.fm for Nikki so people can learn what he's like, see how his character is. Feel free to ask questions here: http://ask.fm/IceQueenNikki
