Well I don`t know how accurate it is, but I do know that the halflings
fear an entity called the Dark Rider or something like that(I don`t have the
book with me now). The possibilities of their being litches in the SW is high
since beings like the Raven came from the SW. You might also want to look in
to the IRON THRONE novel. In it Roele`s army travels into the SW with some
halfling scouts and they get a close look at this dark rider.
