imposter...the warp is at the top of the world in fantasy...litterly there is a giant warp rift there, it's a key part of the canon, from it all winds of magic come. also if you get teh old 1-3rd edition chaos marines some of them come with flintlocks and items from the warhammer fantasy world on their trophy belt. the two have grown more and more distant but the daemmon codex for both fantasy and 40k unless 6th has changed it have been one and the same book all the way up to 5th edition.
