Herumor

Herumor, which is Quenya for "Lord of the Dark", was a Black Númenórean in the Middle-earth legendarium created by J. R. R. Tolkien.

Herumor is mentioned only once, in the passage cited below;

"..because of the power of Gil-galad these renegades, lords both mighty and evil, for the most part took up their abodes in the southlands far away; yet two there were, Herumor and Fuinur, who rose to power amongst the Haradrim, a great and cruel people that dwelt in the wide lands south of Mordor beyond the mouths of Anduin." (from "Of the Rings of Power and The Third Age" in "The Silmarillion").

Theories asserting that Herumor and Fuinur became Ringwraiths are not credible: both were mortal lords of Númenor when Sauron was imprisoned on Númenor, about 1000 years after the first recorded sightings of the Ringwraiths in 2250 S.A. Another character named Herumor is mentioned in "The New Shadow", an incomplete sequel to "The Lord of the Rings" which appears in "The Peoples of Middle-earth". Here, he mentioned in connection with a growing evil cult in Gondor during the Fourth Age, about one hundred years into the reign of Eldarion, the son of Aragorn. This tale, however, was quickly abandoned by Tolkien and cannot therefore be considered definitive or wholly canonical.

In the now defunct and somewhat obscure Middle-earth Role Playing game from the 1980s, Herumor is accorded an extended history, although Tolkien had nothing to do with this publication.
