[Okay, this is a LotR character, but since he was not really developped in the book, I hope noone minds that. Here comes a part of his earlier history, how I see it. For the sake of RPG:)]

He was born in Lothlórien, and raised there. Years later, he began to serve his Realm, sent to protect the borders along with his brothers. He dwelt there and focused on his duties, until a horde of Orcs attacked his people, and many of them died. Being still young and unable to cope with that, he asked for dismission and left Lothlórien. He wandered across Middle Earh for nearly half of his life, seeking comfort and hope that he had lost. Unable to find it, he went back to Lothlórien and turned to the Lady of the Wood. And so he returned to his duties, sent to the Northern border. Taught by the tragedy of old, he is ever watchful. Being a skilled and experienced warrior he was made captain, and leading his people through many dangers he became tough and, some say, too strict. Now and then sent to other Realms as a messenger.
