Ohtar
In the story "The Disaster of the Gladden Fields" found in Tolkien's "Unfinished Tales", Ohtar was introduced as squire to Isildur, the Gondorian king who cut the ruling ring from the hand of Sauron at the end of the Second Age. A few years later, they were leading a small army of Men when a huge force of Orcs attacked. Isildur saw that they were in great peril, and determined to save one of the great heirlooms of his people—the shards of Isildur's sword. Isildur called Ohtar to his side; Tolkien wrote that Ohtar "was dear to Isildur and of his own kin", and suggested that Ohtar was not the squire's proper name but "probably only the title of address that Isildur used at this tragic moment, hiding his feelings under formality".
