Demonic

One minute after Cylius left, giant creatures started coming from all directions each the size of a mountain. Giant dragons, flame python several kilometers long, floating water whales, humongous snow apes...

Although most were large creatures, there were an exceptional few that had a normal size or tiny build. 

All kinds of creatures appeared with a common trait among them, they all radiated incredible auras carrying immense pollution that was changing the environment by the second. 

These creatures while powerful and was qualified to own a vast amount of territory each, they had their share of enemies and friends. 

Constrained by the other powerful monsters, they couldn't hope to be free and do as they pleased like they were in their own territories.
