Elevator Ritual

This game appears to originate on a Korean and Japan website some may recognize as the source of a particular comic that pops up every few months or so on sites like reddit. Unfortunately I don't speak Korean or Japan, so working off of the rough translation found here, I've tried to tease out a clearer version of the rules and instructions. It's unclear whether the Otherworld to which the elevator delivers you is the Shadowside referred to by FableForge in his various games and rituals, or whether it's something else; regardless as to what it may or may not be, however, as always-play at your own risk. This is a real game.
