Morben

Morben (pl. Morbin or Moerbin) was a term used amongst Sindar (and Laegil) that lived in Beleriand. Morbin were the Avari or anybody else dwelling outside Beleriand or entering Beleriand from outside.

Morbin were usually elves (and other peoples) who were hostile to Eldar and Edain. But the word was at once used of the Easterlings who came to the West before the Battle of Nirnaeth.
