Aldarion proclaimed King's Heir of Númenor
Event Type: Political
Age: 2nd Age - Pre-Rings
But when nigh on eight hundred years had passed since the beginning of the Second Age, Tar-Meneldur commanded his son to remain now in Númenor and to cease for a time his eastward voyaging; for he desired to proclaim Aldarion the King's Heir, as had been done at that age of the Heir by the Kings before him. Then Meneldur and his son were reconciled, for that time, and there was peace between them; and amid joy and feasting Aldarion was proclaimed Heir in the hundredth year of his age, and received from his father the title and power of Lord of the Ships and Havens of Númenor.
