Dor Dínen, the Silent Land, was a small, roughly triangular region to the east of Nan Dungortheb that lay between the upper courses of the rivers Esgalduin and Aros. It was crossed by a road passing from the stone bridge of Iant Iaur on Esgalduin to the ford of the Arossiach on Aros. Its southern edge met the forests of Doriath. The Arossiach led to the northern marches of Himlad to the east.
