|Location||Southwesten Eriador, in Minhiriath|
Eryn Vorn is a wooded cape in Eriador.
Located in western Minhiriath, Eryn Vorn was originally part of the vast ancient treescape that covered most of north-western middle-earth. 'The Black Wood' was named by the Númenóreans during the second age.
During the Second Age, however, these forests were decimated by the Númenóreans in their greed for ship-building timber, before being almost completely burnt down by the forces of Sauron during the ensuing war in Eriador.
By the latter half of the second age, the surviving natives of Minhiriath had retreated either north to Bree, or hidden themselves in Eryn Vorn.
Eryn Vorn was probably all that remained of the vast forests in Minhiriath for long years thereafter, but by the end of the Third Age, scattered woodlands had reappeared in much of the rest of Minhiriath.
From T.A 861, Eryn Vorn nominally formed a part of Cardolan, but it was never really under the control of the king. The people of Cardolan were almost completely destroyed by Great Plague a few centuries later, although it is not known how this affected Eryn Vorn.
It is probable that people remained hidden in Eryn Vorn by the Third Age, for although it is clearly recorded that no permanent settlements of men existed anywhere west of Bree by the late Third Age (in "The Lord of the Rings"), it is also said that "a few secretive hunter-folk lived in the woods" of Minhiriath at the time of The War of the Ring (in "Unfinished Tales"). These people we are told were afraid to cross the river Baranduin because the Elves dwelt beyond it.
Presumably, then, any later inhabitants of Eryn Vorn lived a nomadic lifestyle, similar to that of the nearby "numerous but barbarous fisher-folk" along the coast of Enedwaith to the south.
