Sar Mell is a ruined city in western Essos, located on the eastern bank of the Rhoyne just north of its delta. The ruin is located north-west of Volantis and directly opposite the town of Volon Therys. The eastern banks of the Rhoyne lie at the far south-west of Dothraki influence.
In the books
In the A Song of Ice and Fire novels, Sar Mell is a ruin. It is unclear if the city was once a Rhoynar settlement destroyed during the Valyrian invasion, or a more recent town wiped out by the Dothraki.
