Semi-rebus  signe  of the Garden of  paradis , floating in the  sombre . A dynamo, set up here to create compass-confusing magnetism. This small magnet-field also protects this place from some little particles that generally aren't allowed into healthy human environments. Earth has a magnet in its belly, and Mars doesn't... that's why we have people who wonder how to get of the  planète , and Mars doesn't have anyone at all (they left a while ago, not during my watch).
