Bilbo has a riddle of his own for you to solve:
A long beard I have of bristly hair,
But no chin or cheek on which to bear.
Many hands hold me, with ne'er a caress,
Yet I'm e'er the first to clean up a mess.
'It seems that we have an expert riddler here!
'It is Bilbo's turn to present a riddle... you should speak with him and learn what he will pose to me.'
Bilbo is standing with Lindir in the Hall of Fire.
Lindir told you that it was Bilbo's turn to present a riddle and that you should speak with him.
The solution to Bilbo's riddle is somewhere in the Last Homely House in Rivendell. Bilbo awaits your return in the Hall of Fire.
Bilbo is waiting for you to bring him the item that solves his riddle.
