- "In the Shadow Lands beyond Asshai, they say there are fields of Ghost Grass, with stalks as pale as milk that glow in the night, murders all other grass. The Dothraki believe that one day, it'll cover everything, that's the way the world will end."
- ―Ser Jorah Mormont
On their travel east, Ser Jorah Mormont tells Daenerys that the Shadow Lands are said to be covered by "ghost grass", a form of grass that, in Dothraki mythology, will overrun the green grass of the Dothraki Sea and spell the end of the world.
In the booksEdit
The Shadow Lands are a mountainous region beyond Asshai and one of the most remote locations of the Known World. To go to Asshai is sometimes described as to "pass beneath the Shadow". What exactly the Shadow is, or what is casting it, nobody seems to know.
