Who Am I?

This riddles game is based on the trilogy of The Lord of the Rings (books and movies), The Hobbit, The Silmarillion and Unfinished Tales. A character has been picked; a short description of it written. Your task is to know who we are talking about.
The answer, believe it or not, is in front of you at the end of each riddle. Of course you'll be required to use your magical knowledge to find it...
