Agnes' Trouble

Adventurer, you have come at the right time.
Recently, a local named Agnes developed a strange disease which prevents her from sleeping well. Every day, she comes to me for help, and although the medicine I prescribe can calm her spirit temporarily, this sickness will become a significant drain on her body if it is not solved soon.
However, I've determined that the root of the problem is related to the Moongorge, and as such, you adventurers would be much more useful than an old doctor like me.
Please go see Agnes. She can tell you more, and I'm guessing that if anyone can help her, you can.

Did the Highly-skilled Doctor tell you about it?
Hmm... You seem a reliable sort of person. Alright, then! I must ask you for your help.
