Chapter 91

Drogo had once read, in the richly stocked libraries of Qarth, a fragment of Dragons, Wyverns, and Firewyrms: An Unnatural Evolution of the Draconic Species, a work by Septon Barth, the former overseer of the royal library in Westeros—commonly abbreviated to Unnatural Evolution.

In it, Septon Barth had written:

"Death comes from the dragon’s maw, yet death shall not enter it. The eyes are the dragon’s only true weakness. Behind them lies the brain—vulnerable, unlike the underbelly touted in ancient tales. That patch of scales is as impervious as a dragon’s spine or flanks. And as for the throat? Nonsense. Those self-proclaimed dragonslayers would sooner snuff out their own lives than their quarry’s flame."
