He lives in a small forest in southern Denmark. There's a raven wing tucked in the garden gatepost, and a rusty old spacefighter mothballed in the garage.
As you can see, there's nothing wrong with his imagination.
Bran, like many of his generation, is a Star Wars fan. But Bran's literary jag of science fiction can be found in books by authors including Peter F. Hamilton, Neal Asher, Dan Simmons, and a particular fondness for the late Ian M. Banks' Feersum Endjinn - read it, you'll love it!
Bran is Welsh for raven, and Nicholls is Bran's mother's maiden name. The name conjures up images of his pipe-smoking gardening grandfather - an aircraft mechanic stationed in the desert during the Second World War - and Bran's grandmother, and her recipe for Welsh cakes in particular.
Bran is currently working on series one of The Shroud Discord and other scifi projects.
