The Moons, Masser and Secunda (Masser is the pink one). The Moons represent imagination, dreams, instinct, intuition and fears. Prepare to be both inspired and frightened. This can also be a card of mystery and the unseen.
Actually, I think it's a preference for the artist on which numbers to use. I've never been really fond of Roman numerals because they're kind of weighty. Thanks for the feedback, though, and thanks for the fave!
