I believe each writer has their own world they sometimes lock themselves into. Mine is Haven Eclipse, my wacky not-so-safe-place I go to regularly to escape the nightmare of reality. Haven isn't completely perfect, it is sometimes dark but it is a place I can go where anything is possible. Haven is more of an institution where all my characters, both developed and hardly developed, live in peace... well not all of them. My main recurring characters, White Wing, Neofreak, and Logan are usually always in a living hell. Never piss off your writer, they might drop a tank on your head.
