Not only will you feast with gods and demons, but with your dearly departed. This one-time only deal with Ereshkigal and Nergal only lasts for one day. Come and bring offerings to your dearly departed (else, you'll be dining on dust) and share your experiences of the Mesopotamian Underworld with us!

~ Wear old and dirty clothes. The more holes you have strategically placed in them, the better! (No silken kimonos.)
~ Check your weapons and staffs at the door with your good, clean clothes. No weapons allowed! (Yes, Celts. This means you!)
~ Try not to make noise. (Note to self: Make sure the Germanics learn this rule by heart.)
~ When you see a family member, do not behave toward them as you normally would. (You know, like living in Athens during the Plague.)
~ No SANDALS! (Not even if you are a Roman Goddess who got a good deal on a pair of Pradas.)
~ Do not anoint yourself with “good” oil. (Egyptians, this means you!)
