Queen Rhiannon still hadn't regained her full strength after giving birth to Dia.
At the moment, she was only at the peak of the Calamity Rank. But after seeing Antero get destroyed and her daughter taken away from her, she decided to burn her life force in order to save her daughter regardless of the consequences.
But right before she was about to do that, she heard a voice speak inside her head, stopping her from what she was about to do.
While this was happening, Antero's shattered remains swirled like a tornado and began to attack not only Daniel but also the Demigod who had kidnapped his granddaughter right under his nose.
The skies of the Thirteenth Layer now had cracks in it, and parts of it were falling to the ground.
The Succubi all joined the battle to protect their Queen, not caring about the fact that they were fighting against countless Demigods.
