Conclusion!

Throughout Lance's honest narration, Marvin slowly learnt the ins and out of this Universe.

There was a foundation upon which the entire Universe rested.

Even the World Tree, which winded through the entire Universe. Even the Astral Plane and the Void spread from this foundation.

And the foundation of the Universe was Feinan.

This was also the reason that Feinan was the Prime Material Plane.

Feinan Plane was the origin of everything, and Feinan's Plane Will was the original consciousness of the entire Universe.

A Plane Will was a very complex thing. At first, Lance gave it a relatively superficial understanding of things, only intending to use it as a tool to create the world.

And later on, when he found out that the Plane had its own consciousness, he didn't realize how dangerous this fact could be.

When Feinan's Plane Will first started to think the same way that people did, the disaster had already started.
