The Lands of Ice and Fire - a collection of poster maps depicting the world of A Song of Ice and Fire - will be published next week. io9 have released some more sneak peeks of the collection, including our first-ever canon glimpse of Asshai and the Shadow Lands:
Readers of the books know that Asshai is a highly mysterious city located in the far south-eastern corner of the explored world, on the eastern shores of the Jade Sea, five thousand or more miles from Westeros. Beyond Asshai lies the even more enigmatic 'Shadow Lands', the home of mysterious people who always go masked in public (such as Daenerys's sometimes-ally Quaithe). Asshai was first mentioned in A Game of Thrones (published in 1996), but this is the first time it's been officially depicted visually in any form.
