After defeating Garlon, Dame didn't bother to pick up the head on the ground or anything like that. Maybe some would have used it as a trophy for their victory, instead he felt like there were more important things on his mind.
He left the area jumping back to where Safa and the others were currently. He could see that nearly all of the golems and demonic warriors had left the fighting area.
It was clear this was being done by whoever was controlling the golems, as they all would have just been destroyed and crumbled in the fight.
As strong as this power or artifact was to summon a large army of this size, the energy to create such things had to come from somewhere, so there was no point wasting energy on creating things that would just perish next to them.
Which was why Dame had assumed that the Deleter causing all of this had to be watching them from somewhere or was somehow able to observe the whole field.
