He is the keeper of Alcarinar (Aglarach) 'The Glorious Flame' that was previously wielded by Glorfindel and was used to smite the Balrog that persued the refugees of Gondolin within the Echoriath in the Elder Days.

 

Whence Gondolin was sacked, Belegos despaired of the wars of Beleriand. Long had the Noldor suffered at the hands of Morgoth, and he fell into a great despair and abandoned his folk to wander alone. The War of Wrath came and went, and he shied from the trumpet call of the Host of the West. For long years he walked aimlessly among the sinking paths of the west, drawing ever closer to the Ered Luin. When he finally arrived in Lindon, he resolved himself to stay for a while at the Havens and to take a ship to Valinor, for the world and it's toils had wearied him. Ultimately this was not to be his fate. Whilst at the Havens, his friend Glorfindel arrived unlooked for and together they rejoiced at his coming back to Middle-Earth. Belegos was persuaded to rediscover his hope for those lands, and took it upon himself to guard them against evil.

 

Upon Glorfindel's return from the Halls of Mandos, Belegos returned his sword but was bade keep it in the hope that it brought more luck to it's new owner. Inscribed in delicate Tengwar is 'Glorfindel christ, i Valaraukar Dagnir!', or, 'Sword of Glorfindel, the Balrog's Bane!'

 

Whilst occasionaly resting at Imladris when weary of his travels, Belegos has now turned mostly to wayfaring. Far and wide have been his travels and he has seen many marvelous and wonderful, if not perilous sights of Arda.

 

He is now of the Order of the Arrow of Bar-En-Vanimar.
