Bilbo Baggins has completed his book and would like to make certain that his memory of the important locations and events is correct.
'I would hate to ask this of you, ${PLAYER}, but there is another place I would like you to go. The way is quite dangerous, and I simply am not sure whether I should indeed ask it of you, but it is a very important place... it is really where this whole mess began.
'Deep within Goblin-town, there is a cave. I've mentioned it before, I'm sure. A wretched creature called Gollum once lived there. Gandalf says he is related to hobbits, but I just cannot imagine it.
'At any rate, I would like you to find that cave and get me proper directions, as I stumbled into it quite by accident during my adventure with Thorin and Company. But perhaps you should speak with Gandalf the Grey and my nephew Frodo... they might have some reservations about anyone going there.'
Gandalf and Frodo are in Bilbo's room on the first floor of the Last Homely House, in Rivendell.
Uncertain of the task he has set before you, Bilbo Baggins wants you to speak with his nephew, Frodo Baggins, and the Wizard Gandalf the Grey before setting forth on your journey.
Bilbo Baggins is in the Hall of Fire in the Last Homely House at Rivendell.
Gandalf and Frodo warned you of the dangers found in the cavern in the dark. You should return to Bilbo Baggins with their opinions.
