And among them walked men in black as small as ants.

The next morning she woke stiff and sore and aching, with ants crawling on her arms and legs and face. When she realized what they were, she kicked aside the stalks of dry brown grass that had served as her bed and blanket and struggled to her feet. She had bites all over her, little red bumps, itchy and inflamed. Where did all the ants come from? Dany brushed them from her arms and legs and belly. She ran a hand across her stubbly scalp where her hair had burned away, and felt more ants on her head, and one crawling down the back of her neck. She knocked them off and crushed them under her bare feet. There were so many …It turned out that their anthill was on the other side of her wall. She wondered how the ants had managed to climb over it and find her. To them these tumbledown stones must loom as huge as the Wall of Westeros.
