A makeshift tabernacle attached to the mouth of a cave is manned by a smiling acolyte in a plain robe. A trail of smoke—saccharine incense—trails from within the folds of the tent. You peer into the dark interior and see a large chest, painted in fine script with the word: Donation. The chest is guarded by another acolyte, much taller and broader of frame, and with a spiked club strapped to their hip.
