A proud Dúnadan, Calimehtar was the second son of King Calimmacil of Gondor (T.A. 1294-1304) and younger brother of Minalcar (Rómendacil II). He resided in Pelargir rather than Osgiliath, for he was Gondor's High-captain of the Ships. It was hardly surprising when he supported the disenchanted Sea-lords of Lebennin during his brother's reign. Castamir, Calimehtar's grandson, would later induce the Kin-strife (T.A. 1432-47).
