The younger brother of Narmacil I, who succeeded his childless brother as King of Gondor. His reign was short and unremarkable, lasting just ten years during which the actual power of the realm was wielded by his tireless son and regentMinalcar. On Calmacil's death, Minalcar took the throne himself under the famous name of Rómendacil II.
The date of Calmacil's birth appears only in The History of Middle-earth volume XII, The Peoples of Middle-earth. It cannot therefore be considered completely reliable.
