The rules are simple. One person chooses a character from the trilogy (and we're doing a movies edition now, so only choose characters that appear in the movies - however, it's okay to use information from the books as well, as long as the characters appear in the movies too). He or she then posts a clue about the character, and the task for the rest of us is to guess which character the person is! The one who makes a correct guess posts a new clue (after the answer has been confirmed correct).
To make the clue writing a little more fun, let's say that the clue should be between 2-5 lines.

If you are a HOLTS member, you'll get 1 silmaril for each correct answer!

Okay, here goes the first one!
Part of the famous fellowship
that departed from the house of Elrond
One moment of weakness
almost brought failure to us all
I found peace before the end
Who am I?
