[Egg The Small One]

Good day folks


I started to watch  TheFlexibleStragestit this mod game play at YouTube and I get game sick again . so I am here .


I know this is smart and experienced community  so I have a question-

Does anyone now any Other books from G.G.Martin about Westeros besides Ice and fire series and Knights of Seven Kingdoms?
Like YouTube is full of content from series, about Westeros history, house names and interesting facts ( and tv show actors  voices are on this videos ) So I started to think, where did they get this info ( specifically about history) ?

There is a book called The World of Ice and Fire. This contains quite a lot of history from the world of ASoIaF.
