[Congratulations, you've triggered the hidden task: Harrington Hugh's Last Wish.]
[Task contents: go to the fifth floor of the Underwater Prison, look for surviving Forest Elves and save them.]
[Task rewards: For every elf saved, Forest Elf Clan reputation +100. After rescuing all, you'll receive Harrington Hugh's Elder's Token (Can be exchanged for 5000 reputation in Emerald City.)]
"Only reputation huh..."
Mu You looked at the task content and shook his head in disappointment. He thought that such a difficult task could at least yield some material rewards, but it only offered reputation.
But thinking about it, it made sense. Those people were imprisoned indefinitely, they must have had their possessions confiscated a long time ago. That Elder's Token was probably all the old man had left.
[You accepted Harrington Hugh's Last Wish.]
[The old elf revealed a relieved smile and pointed you towards the path within these caverns.]
