The Plain of Srevi (🔊) is a vast expanse of sparsely-inhabited grasslands and savanna in southern Addar. Beginning at the southern fringes of the Desert of Terza, the plain stretches nearly 600 miles southeast to the coastal plains along the shores of the Silver Seas. The deep Gulf of Hedrin and the foothills of the Sax Mountains border it on the east and west.

Srevi's interior is trackless and poorly charted, but a few small, nomadic groups of humans, orcs, and other races are known to make their home in the sea of waving grass, foraging, hunting grazing animals, and avoiding the predatory felids who stalk the plain. Some travelers also report encountering "grass men", but their existence and nature is unconfirmed.

The far eastern and northern portions of the plains are controlled by the Darklord Skeleus and lie within his Shadowlands.
