['thul]

oh? is it not a fight of right vs. wrong?

Martin may have many viewpoints, but that does not change the fact that each part is just such a fight.

Also, is not the whole story a fight of good vs. evil?
Those fire-worshippers and the White walkers... If warmth vs. cold is not a symbol here for good & Evil, then what is it?

By boil down, 'thul mean boil down completely. Boiled down to the point where it is no longer characters, but instead forces. Each of those forces change the balance in the equation slightly. Some directly by heaping weight on one side of the scales, others by moving weights around on the plates, changing how much a weight affects the balance.
