Serena found a more secluded location nearby before re-entering the Heavenly God Plane to find Claire and Malefice.
She absolutely could've gone straight there in the real world, but she would be able to travel far faster in that plane.
Plus, she wasn't that far away.
The Heavenly God Plane was much less expansive than the Heavenly World since it usually only showed enough space to contain all the battles taking place within.
There were a lot of Gods fighting right now, including Hugo, Persia, and the 16 Swords, but they were all roughly around the same place.
Malefice and his main subordinates had all moved together, after all.
Nevertheless, it wasn't hard for Serena to find the location. Claire's summons weren't exactly quiet.
And when she arrived, the first feeling that set in was confusion.
'This is…?'
It wasn't what she was expecting at all.
