Earth despite her best efforts to escape and kill blood moon has been damaged, even though ruin doesn’t wanna kill anyone in the celestial family. He still keeps her then moon shows up, trying to kill either blood moon or ruin. To try and get solar back he’s using negative star power to kill them. However, this will kill earth as well. He doesn’t give a damn he just wants solar back. Monty has been damaged so he can’t help.
