A lord of the Teleri in
Middle-earth, Círdan was persuaded to remain in
Beleriand with some of his people by Ossë when the other Teleri were taken into the West by
Ulmo. Lord of the Falas during much of the
First Age, he removed to the Isle of Balar after the
Nirnaeth Arnoediad. At the end of the First Age, with the destruction of Beleriand, he moved eastwards and founded
Mithlond, the Grey Havens, on the Gulf of Lhûn.
He remained in
Lindon throughout the Second and Third
Ages. Throughout the
Second Age, that land was under the direct rule of High King
Gil-galad. At the time of the fall of Eregion,
Celebrimbor sent two of the Three Rings north to the High King, and Gil-galad in turn passed one of these to Círdan;
Narya,
the Ring of Fire. At the end of the Second Age, Gil-galad fell in the
War of the Last Alliance, leaving Lindon without a ruler. His natural heir would have been
Elrond, who had long since removed to
Imladris, and so Círdan took on the leadership of the Elves west of the
Blue Mountains.
Círdan continued to maintain the havens at Mithlond throughout
the Third Age and into the Fourth. When the
Wizards arrived in Middle-earth, he perceived that
Gandalf was the wisest of them, and gave him
the Red Ring to bear in secret. He took an active part in the
events of the Third Age, too; it was his mariners, for example, who sought to rescue Arvedui the last King of Arthedain. He was still
the master of the Grey Havens at the end of the Age, when he saw the
Ring-bearers' White Ship, that he had held in preparation over the long years, pass into the West.
