Ser George

I picked up on this as well. In addition to being such a delightful turn of words, both Larry Niven and Ursula K. Le Guin have used variations of cellar door as nouns and I can imagine that GRRM was tipping his hat to them as well.

Another thing, is it just me or is the Night's Watch very similar to the early days of the Marine Corps? By this I mean, the Marines and Night's Watch take the outcasts and potential convicts and through rigorous training turn them into a fighting force. The dedication to your "brother" is also very similar.

In George Herbert's poem The Hound of God. God is fairly vicious and focused on his enemy. Sandor is vicious and is focused on Gregor. While fairly implausible it is an interesting connection.
