DON'T!!! All of us posting here have read up to the end of A Feast For Crows, plus the Hedge Knight stories, so don't come back until you have read the four books. There are just too many spoilers in these threads.
I will say that if someone is curious enough to Google a bald reference in here (which are meaningless unless you read the book, or google the reference), then the spoiling result is their own damn fault, not the fault of any of the vague referencers in this thread, which seem aimed at getting X'Nedra to read the book. They (and I) may have gone towards the line, but no where near it, let alone over it.
