Erendis was the wife of Tar-Aldarion of Númenor and a descendant of the First House of the Edain. Aldarion was devoted to the sea and his ships; Erendis did not share this love, and so their marriage was an unhappy one. They had one child, a daughter (who later became Queen Ancalimë, the first ruling Queen of Númenor). After that, she withdrew from her husband’s life, but in old age desired to reconcile with him. In SA 985, she journeyed to Rómenna to greet him, but was said to have perished at sea.
