Círdan is first introduced as a shipwright and Lord of Falas. He is known to have been important in the First Age because of the aid his ships brought.
But the realm of Nargothrond extended also west of Narog to the River Nenning, that reached the sea at Eglarest; and Finrod became the overlord of all the Elves of Beleriand between Sirion and the sea, save only in the Falas. There dwelt those of the Sindar who still loved ships, and Círdan the shipbuilder was their lord; but between Círdan and Finrod there was friendship and alliance, and with the aid of the Noldor the havens of Brithombar and Eglarest were built anew.
Afterwards, he went to stay at the Isle of Balar when Falas was destroyed and subsequently resided at the Grey Havens in the Second and Third Ages.
Throughout all this his origins are not mentioned, though it is known that he was a Telerin/Sindarin elf.
