There is no such thing as an offering.

Exploration Stage: Solstice Meadow
From: Pear Lady
Description: It is human beings who sowed the seeds of discord. Can you believe it? There used to be an important tradition of leaving milk porridge on the stump for the forest creatures, but now...look at this plate!
Completed: The old porridge is completely covered with moss. It has been a long time since the last offering to the spirits was placed. I tried to remind people by showing them visions of the freshly made porridge, but this only frightened them.
