Gandalf would like you to bring news of the hobbits back to Ashlimb, who first put you on their trail.
'Oh...and one more thing before we part ways, ${PLAYER}. You must not forget about the good Ent who sent you on this fanciful wild goose chase.
'We cannot start a flood without the first raindrop. Be sure to tell your sleepy friend all that you saw. Farewell, good ${CLASS}!'
Gandalf is atop Treebeard's Hill, alongside a horse you have never seen before.
Gandalf has one more thing to say to you.
Ashlimb is at the eastern edge of Fangorn's eaves, waiting to hear of the hobbits' fate.
You should return to Ashlimb and convey Gandalf's tale of their meeting with Treebeard.
Ents can be found throughout Fangorn. You should search north-east of Ashlimb for other Ents you can help, as Gandalf bid.
