Every several years, the moon successfully ascends to dethrone the sun. That is when the worlds invert, and night invades the day.
The moon absorbs all the dead spirits that fall down into the underworld. This gives them a home while the courts of the sun prepare for their trial at its appointed time so that these ghosts don’t muck up the earth too much. Every night, the earth flips over, facing the moon, allowing some of the spirits to transcend to the world and find their kin or take care of some unfinished business.
But this is not always enough. Every once in a while a contingency of the moon ghosts make a climb up to the heavens during the day to supplant the sun and finish its job filtering ghosts from the earth. We call these an eclipse.
The moon turns the earth into night. The animals know what is about to happen and freak out in horror. The humans, mesmerized, simply stare up at the sun.
Like bats, thousands of spirits pour out from the moon and make their initial jump into the earth. You can hear their strange whoosh in the air all around. They take the spirits of the most persistent ghosts who refuse to sink down and join them below.
They can only hold back the sun for a few minutes, though, and eventually, the sun throws them back down. These ghost soldiers know this and go straight after the ghosts they are set to capture to bind them up. Some soldier ghosts, though, once free secretly remain on the earth, often the first deserters to be sought after next time around.
Through all of this, they cleanse the earth of the spirits of old, that is until more spirits can accumulate. The earth’s environment must adjust to having no spirits. You’d think this would produce consistency, but our ecology systems were built around the presence of these ghosts and spend the next several days readjusting. Eventually, however, it instills a brighter world until too many spirits accumulate again, and another cleansing is needed.
