I will start with something trivial, this one will blow ASOIAF fans. I've been reading The Morning of the Magicians and the second part of the book as a lot of references to "the battle of ice and fire" and "fire and blood".

I am aware that people have already linked, with some logic, Martin's masterpiece theme to norse mythology but the thing is that MOTM has this reference I mentioned in the context of ariosophy which inspired nazi occultism and is partly based in norse mythology.

MOTM was published in 1960 in France, authored by Louis Pauwels and Jacques Bergier. The "Weltsehre" or ice and fire theory is the work of Heinz Hörbiger who greatly influenced Germany with his radical cosmogony.

I do not think Martin has inteded to associate his work with radical ideology. Most likely he read MOTM in his youth and was influenced by it's ideas or he simply read a lot of in depth material about norse mythology.

Anyway, MOTM was published in the US in 1964 and the book is a must read for CT's. As for me, being a ASOIAF tard, I was proud that no one has made, at least visibly, a connection between these two unexpected elements.
