Legend speak of a musty old market square covered in eldritch symbols, somewhere in the forest. If asked further, people will tell you, it’s definitely just a myth and you shouldn't worry. In addition a stranger whose name is always forgotten asks of the players to travel there with him.

People have heard that a minister of treasures was seen with a magician down near the prison and there was a yeti. People heard it from a trickster spirit, so it is absolutely true.
