Maeve's plan was to weaken and possibly seriously injure the Beast King using the Apostles she brought with her.
Once the Domain disappeared, she would immediately use her artifact that would teleport her to the underground Headquarters of the Divine Army, escaping her current situation.
Since the Beast King had changed sides, she no longer treated him as a comrade and ordered all of her subordinates to attack him without mercy.
Although they were reluctant to leave her alone, the fifteen remaining Apostles all activated their ability and turned into Pseudo-Supremes.
They had seen how the Beast King had dealt with their comrades earlier, so they wouldn't allow the same thing to happen to them.
A moment later, the fifteen Pseudo-Supremes and the Giant White Tiger clashed.
Loud explosions erupted within the Dimensional Domain, destroying the city devoid of any of its citizens.
