George R.R. Martin revealed on his Not a Blog that he had decided to go and update his book samples pages at his official site with a new The World of Ice and Fire sample… but it’s not quite a sample from the book: “The Westerlands” is in fact George’s original write up of Westerlands history, one of a number of such write-ups he did as his contribution for the book. Due to size constraints, Linda and I then worked with our editor Anne Groell to compress it down to fit the book.
Now, one note of caution: this is an unedited, unpublished text. In fact, purusing it, it’s a very close match for the original text George sent, before we turned it around with some comments pointing out some continuity issues. George is aware of them and will doubtless incorporate them in the future if he decides to publish it, but in any case there are differences between the two texts because we incorporated those necessary changes and fixes into TWoIaF. Some have asked us if we can at least consider all details not contradicting the books and TWoIaF as “canon”, but I’d again underline the fact that this isn’t really a published text. Until it’s in a fixed format—as in, published in a book or an anthology—it’s not canonical, as all unpublished details are entirely subject to change at George’s whim. I’d guess very little of it will change if George did decide to publish it, beyond those things already fixed for The World of Ice and Fire, but that’s where it stands.
In any case, go read it!
