I am the blood of the dragon

The Great Masters had used the pit as a prison. It was large enough to hold five hundred men… and more than ample for two dragons. For how long, though? What will happen when they grow too large for the pit? Will they turn on one another with flame and claw? Will they grow wan and weak, with withered flanks and shrunken wings? Will their fires go out before the end? What sort of mother lets her children rot in darkness?

doctaaaaaaaaaaaaaaaaaaaaaaa:

Viserion’s claws scrabbled against the stones, and the huge chains rattled as he tried to make his way to her again. When he could not, he gave a roar, twisted his head back as far as he was able, and spat golden flame at the wall behind him. 

Rhaegal had been harder. Perhaps he could hear his brother raging in the pit, despite the walls of brick and stone between them. In the end, they had to cover him with a net of heavy iron chain as he basked on her terrace, and he fought so fiercely that it had taken three days to carry him down the servants’ steps, twisting and snapping. Six men had been burned in the struggle.
