Lizards and Men

"ANIMA!!!"

There was a giant lizard-type anima hanging on the ceiling at the exact spot that the crystal was protruding from, but for some reason, they could not see the Anima when it was only being illuminated by the light of the crystal. It was only when the flames covered it that they were able to see where it was!

The anima immediately raced out from the light of the flames and everyone in the cave went into a fighting stance as the Anima disappeared into the light of another crystal. James shouted at the flame user to bring up a large bonfire! They needed to create more light so they could see where the anima went! But before James could chase after the Anima, he was blindsided by another Anima who appeared from behind and slammed into him!

Boom!

The anima sent James into the wall, and James put his hand in front of his face as the Anima used its leg to kick James deeper into the rock!

What the hell is this power!?
