I really love some Skyirm quotes;
"What is better; to be born good, or to overcome your evil nature through great effort?" -Paarthurnax
And just about everything Paarthurnax says.
"Funny how you can set aside your morals whenever it suits you."-Lord Harkon
"If by message, you mean shoving a sword through his gullet"" and "I still think you should take them all out like you did Deadking Torygg"-both of those are Galmar Stone-Fist.
I have claimed Alduin, the mighty dragon! He shall one day return to bring forth the end of time, and fulfill the prophecy of the world eater.
