AfterWorld: The Universe Card in the Crowley Deck may be illustrative of Mars colonization in the literal sense. Though the Sun Card – (four planets away) or “Moon” in the Rider Waite Deck, could represent living off-planet. Meanwhile, the moon is much closer to Earth than planet Mars. Mars is roughly 128 million miles away – requiring six to eight months of travel, and the moon is about 238,900 miles distance, taking only three days. (Whereas a trip to Titan moon could take up to seven years).
Astrology: Aphrodite had a side family with Ares (and daughter Harmonia), and when the God of Fire discovered it, he trapped and exposed them. (Venus and Mars) create the perfect coupling, but if outside influences intercede, it can downgrade the nature of the relationship.
