GRRM's Original ASOIAF Outline - What Can We Learn

when George RR Martin first began work on a song of ice and fire he had to sell the series to publishers. This caused him to right a pitch letter that has since leaked online and become known in the fandom as "the pitch letter" or "the original outline" today I want to go over this outline and some of the wild and crazy things that were supposed to happen in our story, things like a love triangle between Tyrion Arya and Jon Snow. Surely nothing so crazy could really happen... right?
