Azor Ahai and the Weirwoodnet - The Original Sin of Ice and Fire

This is kinda sorta my grand unifying theory of how all the Azor Ahai / Nissa Nissa / Lightbringer / dragons stuff directly connects to Westeros, the first Long Night, the Others, and the weirwoods. Renly's death at the hands of Stannis's shadow is the perfect role-play of the entire theory, so here it is! Enjoy!
