If The Long Quiet and The Shifting Mound (Slay The Princess) were both entities that exist in the world of Tensura, what do you think would they be?

I thought this could be interesting because they are both very powerful entities. Here an explanation to those who haven't played the game yet.

The Long Quiet (left picture): He is an entity that was made by a mortal who managed it to severe the cycle of life and death, and created 2 new entities from it. From the concept of stagnation, nothingness and emptiness he formed The Long Quiet with the intention to erase The Shifting Mound. Note: accord to The Shifting Mound, if The Long Quiet dies, it would be bad for the universe as well because a world without pause would be a world of constantly change. Birth, life and death would all happen at the same time without a true end.

The Shifting Mound (right picture): She is the other part of the cycle of life and death, and is the literal embodiment of change and transformation. This includes life, death, time, reality, begin, ending and similar. To prevent the own universe from dying, the mortal responsible for her creation created The Long Quiet with the intention to kill her and remove the concept of death/ending permanently from reality, creating a world of stagnation where nothing changes. To achieve this he also created a dimension inside The Long Quiet (yeah The Long Quiet is also a place. Basically the void or end-point where nothing exists) and let The Long Quiet perceive her as a mere princess to make her more vulnerable.

This is a rough summarization. I tried it to keep it as spoilerfree as possible.

Now, I personally think they would probably be on a level like the Greater Spirits. So, perhaps in the world of Tensura they could be Greater Spirits? Maybe even True Dragons? For demons, angels and mere elementals they are way too powerful.

What do you think?
