Frodo has decided that he is ready to relax from the ordeal of his adventure, but your own adventures continue.
'Thank you for easing my mind and my heart, ${PLAYER}. Gandalf has returned, and now I think I see the makings of a conspiracy! But thank you for the kind words, and I give my thanks to Gandalf as well. I am very fortunate to have such friends as you!
'I am ready to have a rest, and an end to adventuring. I shall be content just to see Bilbo again, and to return to the Shire. I will write down my part of the Quest of the Ring, all of it, and I will be thankful for the opportunity to live in peace!'
Mithrandir is in the bower that was prepared for Frodo on the field of Cormallen.
