This month`s Dragon has an article on Ghost Elves, its good stuff and immediatly usable by BR if we ditch the backstory of the pit-fiend for the more familiar story of Deismaar and the severing of the Shadow World from this one. Depending on the location of your campiagn, this material could be applied to Tuar Annwn in the Heartless Waste, it could apply to Seelie of elf-like appearance (or other appearance) or it could be mined for ideas for any Shadow World beings. I find the idea an intriguing one, as the SW is significant to my campaign.
