Sun Sword

It has a golden hilt. There was a little hollow in the pommel that had once held a magnif- icent topaz, which had long since been removed and put to far better use. Its blade shone with a yellow radiance so intense that causes one's vision filed with spots and skinto itch and sting as though he had been too long in the sun. Its light radiates and comes beaming back from every direction, filling the chamber with all-encompassing radiance that washed out even the faintest hint of a shadow.

It was stuck in a large block of granite in a low vault in the Faery Realm.
