The Silver Sea was an inland sea or large lake located in the north-west of Essos. The sea was surrounded by verdant grassland and was used for both transporation and fishing by the kingdom of Sarnor, which grew up around its waters and extended west and north-west.
The sea began to shrink several centuries ago for reasons that remain somewhat unclear. Today the waters have fallen so that once-great ports along its shores are now landlocked ruins and Dothraki khalasars can ride at will over the lands it once covered. Three small lakes are all that remains of this once substantial lake.
