Ghiscar is a region of southern Essos located on the eastern coast of the Gulf of Grief. Old Ghis is found within this region. Astapor and the Worm River are north of the Ghiscari hills. South of Ghiscar are the Ghiscari Strait and some islands, including the large island Ghaen and a small island with the city of New Ghis.
Ghiscar was conquered by the Valyrian Freehold during five Ghiscari wars, however. The Ghiscari were reduced to High Valyrian-speaking slaves of the Freehold. The Ghiscari regained control of the slave trade after the Doom of Valyria.
