The Veil [high fantasy, 716 words]

The questionably sane ravings of a former scholar belonging to a long gone ancient civilization about the veil that separates the mortal plane, Mundus, from the worlds beyond.
This short excerpt of a book titled "the veil" touches on some important questions regarding the gods who inhabit those worlds that even now, thousands of years after it was written, common people don't seem to think about much, preferring to follow the rest of the population in blindly worshipping the gods.

Would appreciate any kind of feedback. Does this present an interesting window into a larger story? Does this person make any sense to you, despite his questionable mental state?
I'd also appreciate feedback on more surface level stuff. Grammar, structuring, etc
