Separation

The next second worm light covered both Dandan and Morana after which a blue rune appeared on her hand. When the contract was concluded she could feel every nook and cranny of this realm and she could feel the control she had over it. 

Morana instantly understood the situation and couldn't help but marvel at the situation. 80% of this realm was covered in potent dark mana. It might be poisonous to everyone else, but to Samael, this was the best kind of tonic for his recovery.

"I will leave the rest to you." Said Morana as she looked at him and Samael disappeared from everyone's sight.

Acheron and others didn't understand what was going on but as the spirit of the realm, Dandan quickly understood the situation.

After dealing with dark mana Morana sealed every entrance to the realm except the one that let dark mana in. After all, if she sealed that one, where would Samael get his tonic?
