Wraiths

A wraith is someone who has been killed yet lives on by some dark sorcery (necromancy or a Morgul-blade), or someone who died in darkness or serious dishonour (the latter are comparable to popular culture's notion of ghosts).
== History ==
=== First Age ===
During the First Age, the love-sick Gorlim, having betrayed his comrades-in-arms, appeared to Beren as a wraith, confessing what he had done.
=== Second Age ===
During Sauron's influence and rule in Middle-earth, he swayed and corrupted nine powerful Men of Númenórean and Easterling stock by giving them each one of the nine Rings of Power. Afterwards, they slowly faded into darkness, becoming Ringwraiths enslaved to the will of Sauron, fated to roam the world until their end.
=== Third Age ===
The Dunlendings feared that Helm Hammerhand was a wraith that wandered through Rohan as its protector.
No other evidence of any other wraiths are recorded as existing in Middle-earth, save for the Ringwraiths, who continued in the East and in Minas Morgul and were dispatched to search for the One Ring. When Frodo was stabbed by the Witch-king of Angmar he was infected by the evil magic from a Morgul-knife; if Glorfindel had not saved Frodo, he would have eventually become a wraith himself.
