He once was a hobbit, just like any other,
Until one day he slew a brother.
He was supposed to be a friend, supposed to be trusting,
But what was found got him evil and lusting
For an artifact which embodied immense power
And as time went on made this man even more sour
He became slender, his hair fell out, and his skin turned gray.
He became a cavern dwelling monster that didn't avoided the day
For years until power was stlen from him.
Now he's got nothing but a whole lot of phlegm.
He claims he can here it sing.
Who is this creature that hunts his precious thing?
