The moment the Divine Shackles appeared, Marvin knew that this battle couldn't be avoided.
He knew that the longer Dark Phoenix remained in Wayne's body, the more dangerous it would be for Wayne, but he had no choice right now.
The only route left to him was a bloody escape path paved by the corpses of these irksome Clerics!
Divine Shackles was a very powerful Divine Spell Ritual.
It could not only seal a space, stopping people inside from leaving, but it also stopped those outside from entering.
The followers put out the banners of their own respective Gods while the others chose to wait and see.
Marvin's Perception wasn't blocked, so he could feel many pairs of eyes watching this forest with attention.
They had no plans to hide themselves.
This battle had more implications than just private grudges.
