Lonely Mill

Description
"This distant mill seems remote and unsafe. While townsfolk and villagers can rely on their walls, neighbors, and guards, hermits seeking solitude always risk running into trouble be it from harsh elements, greedy robbers, or things stranger yet."

Event
This location is only available after starting Mother of Monsters. It still requires discovering, however.

Upon reaching this location, the baron{ess} finds a group of goblins cheerfully celebrating at a windmill. Rather than becoming hostile, the goblins invite the party to join them.

Celebrate with them
This will require that the main character complete (but not succeed at) a Stealth and several Constitution checks, and then finish some goblin poetry. At the end, you will receive the location of the Goblin Village.

Attack them
The goblins scatter, ending the illustrated book event.
