So where is Casterly Rock castle and the Lannister lands again?

If the medieval lands of Westeros, created by George R. R. Martin, confuse you, whether you are a fan of HBO's "Game of Thrones" show or of Martin's "A Song of Ice and Fire" books, perhaps a well-designed map will help you?

A graphic designer named Michael Tyznik has made a series of maps inspired by actual subway maps. There is one of the Westeros continent and its seven kingdom, a bigger-picture map of that world and relevant legends explaining it all.

"Inspired by the work of Cameron Booth and his awesome Transit Maps Tumblr, I created these rail maps of Westeros and The Known World. Hopefully fans will notice some small touches -- the closed stations along the Wall Line, for example."

Tyznik is selling prints on inPRNT, but also posted the images to Flickr.
