Aldarion founded the Uinendili, a guild of sea-farers, in honour of Uinen, goddess of the Sea. He succeeded to the throne and became known as the Mariner-king. He established Vinyalondë (later called Lond Daer), the first Númenórean settlement in Middle-earth. This port provided access to the great forests of Eriador, which the Númenóreans needed for ship-building.
