NiGHTS into Dreams (Part 3 Claris Final Boss and Ending)

Going through the rest of Claris' Stages. Fighting the Final Boss Wizeman, and watching the Ending, and Credits.
I mentioned that I had though I remembered reading that Wizeman was an outsider in the Dream World, but double checking the Wiki it seems like he is meant to be some sort of Dream Deity? The Japanese manual apparently says he is the first intelligent lifeform in the Dream World, and NiGHTS (along with the other enemies) were made from his Soul.
