Long ago, two ancient Eldritch Abominations ruled the planet Cyra. Kith, the giant tick-like beast that drains the thermal energy out of the environment, and Eas, who is the planet’s ocean. After centuries of war between the two, a group of super human mages decided to banish Kith to space. They succeeded, but now Eas had no competition. He reached into space and pulled the moon from orbit, plunging it into his depths.
So here is my question, how would this change the planet? Kith is now serving as the moon for the planet, but he is much smaller than the original moon. Now that the moon has been pulled into the ocean, how will the ocean level change, what will happen to the tides, what will happen to the planet in general? Assume the planet is earth-like, and the original moon is roughly half the size of earth’s.
