This is a shrine. You may ask what it's a shrine for? Well, it's to appease the demon spirit that lives in these parts.

And what best to appease this particular demon spirit? Why, with an offering of sweet things, of course!

If you hang around long enough, you may even be lucky enough to see him partaking of his offering.

Don't expect him to be thankful, though. He's not that sort of spirit. Vashtiel: MINE!
