Tide - Lunar Decay

The Earth and the limitless beings inhabiting it is orbited by a singular entity, Tide. Tide is one of many strongs who opted to inhabit a celestial body. Terrible investment in this case. The planet once the size of Mars has been reduced to a moon forced to forever orbit Earth after their collision around 4.6 billion years ago. Beings like Tide have the sole ability to absorb other beings weaker than it through its massive aura, only one at a time. Tide was once the most powerful strong in the Solar System because of this power.

Remember the collision between the Earth and the Moon? Yeah that was highly influenced(directly caused) by Urn - The Petty Ranger. Out of nowhere. What followed was a failed attempt to absorb her. Urn retreated to the asteroid belt and Tide was left powerless, hoping for the day Urn gets close enough to absorb. Tide's power slowly decays as meteors are thrown at the moon's surface, decreasing its radius and that of Tide's aura.
