The patron deity of potatoes. Has the power to turn blasphemers in His sight into a shower of oysters. There is a tantalizing hint in Making Money that he is the originator of the Potato Cult of which Mr. Tulip, and in the end Mr. Pin, were believers. In Making Money, there is passing reference to a potato-based religion requiring its devotees to wear symbolic golden tubers on a chain about their necks, which is beginning to gain ground in Ankh-Morpork. It may be that Epidity is gaining ground in the divinity stakes and is one to watch. He is celebrated in the month of Ember, which The Celebrated Discworld Almanak notes is the season of potato-harvesting just before winter.
