Maybe Valar from Valar Morghulis probably comes for the Valar of Arda, they are the 'gods' of Tolkien's universe.

Casterly Rock is inspired by my home xD Really, look at Gibraltar in Google Images. Martin visisted there once... before I read the books that is, or even the series. Else I'd kick him in the balls and kiss him afterwards. One for the feels, the other for the fanboyism.
