Bang!
Slayer returned to the Fantasy World, collapsing into a mountain in a hurry that he flattened in response, ignoring the natives living there that were crushed like ants.
He got up from the crater and groaned, only feeling safe in the security of the defence provided by the Fantasy World. Currently, there were hundreds of worlds within the universe where the Fantasy World was situated.
Each Profession controlled a few of these worlds, being empowered in response. The stronger their development, the more robust the fate of the Fantasy World became. And the greater this growth, the harder it became for even Zaira to affect the timeline or foundation of this world.
In his home ground, he had the confidence in resisting any enemy. Moreover, Slayer had been carefully affecting the neighbouring universes, causing them to be affected by an element of chaos that he carefully extracted from one of Mystique's worlds.
