Antheron (Annatar in the original Tolkien legendarium) once taught the Elves how to craft the Rings of Power, which is apt as his name is Sindarin for "Master of Gifts". He appears in an instance where he has promised to teach Narmeleth about his knowledge of ancient ring-lore, if she comes with him.
