That night Tyrion Lannister dreamed of a battle that turned the hills of Westeros as red as blood. He was in the midst of it, dealing death with an axe as big as he was, fighting side by side with Barristan the Bold and Bittersteel as dragons wheeled across the sky above them. In the dream he had two heads, both noseless. His father led the enemy, so he slew him once again. Then he killed his brother, Jaime, hacking at his face until it was a red ruin, laughing every time he struck a blow. Only when the fight was finished did he realize that his second head was weeping.

This is how his story willl end. The hand of the king, Lord of the casterly rock, the lion but his mental health is dying.
