The Dothraki Sea is a vast steppe, with seas of a grass the Dothraki horselords inhabit and graze upon. Contained deep within is the Dothraki city of Vaes Dothrak.
The Dothraki Sea is east of the Free Cities, in the inland of Essos. There is one large mountain in the region, the Mother of Mountains. The mountain rises at the heart of the Dothraki Sea.
The only city here is Vaes Dothrak, which is at the center of the Sea. It is the home of the Dothraki peope and packs of wild dogs and herds of horses.
