Fuinur was a Númenórean who had been turned towards darkness after Sauron had been brought to Númenor. He then journeyed to Middle-earth and rose to power among the Haradrim. When Sauron returned to Middle-earth and assailed the realm of Gondor, Fuinur and a fellow Black Númenórean named Herumor apparently joined Sauron's forces.
Fuinur apparently means "Man of Shadow" in Quenya (from fuinë, 'shadow', and -ur, a masculine suffix).
