Apollo and Artemis were fighting over spotlight they throw stuff at each other. Apollo missed and hit earth making a small crater in an island. So Artemis ignored him.
Apollo asked Artemis if she wanted to stay in the day sometimes with him.
Until one day Artemis got power hungry and went in front of Apollo blocking the sunlight. Apollo got mad and they started fighting again. But when they met up with the other gods and said that it looked like it would please the people. They agreed to do it when the people pleased them.
The people didn't please them for a while so Artemis did it without Apollo permission. Apollo got so mad that he came out the sun and punched the moon hard as he could hurting his sister.
Lanching the moon into the same island.
They made up and Poseidon filled the crater with water.
