Earthfast Mountains

The Earthfast Mountains (or simply the Earthfasts) mark the western border in the south of Impiltur in northeast Faerûn with the Vast, to the west, in North Faerûn. They are jagged and only slightly less harsh than the Earthspur Mountains to the north. Although there are deposits of iron and silver here, the poor conditions required to mine the ores has meant that only a few mines exist.

Geographical features
The Hill of Tombs is the southernmost point in the mountain range, near the coast of the Sea of Fallen Stars. Fire River originates in these mountains and flows west through the Vast into the Dragon Reach.
