Mamodo World history/chronology? (ZB2 spoilers)

One interesting thing about ZB2 as opposed to the original is that we're getting to visit the Mamodo World and learn a bit more about its geography and history. The original manga, set entirely on Earth, gave us only a few tidbits, but we're getting a lot more now. I've decided to throw together some interesting facts we've learned about it for discussion and consideration.

To begin, in the final Gash Cafe in the Kanzenban, we learn that the Mamodos did not create the Spellbooks; rather, the books are sentient beings that brought Mamodos and humans together to save them from an invasion, presumably by the same force invading in ZB2 or their ancestors. Apparently, the books broke some sort of rule by doing this so it wasn't a decision made lightly.



It seems precisely what the books did that allowed the Mamodos to win the war was that binding their magic to the books prevented it from being stolen by the invaders' vacuum dragon thing, as seen in ZBII ch.31:


The Ancient Egyptians knew of the Mamodos and left the mummies and stone spell books behind in anticipation of the current crisis. This would've been around 3000 years ago. The hieroglyphs refer to the Mamodos and the Egyptians as "friends" so it would seem the thousand-year battle system was in place that far back, so three cycles before the one Zatch won and two before the one Dauwan won. (ZBII ch.4)


And we recently saw ruins built to honor the Mamodo King of 10,000 years past. So the Mamodos had a civilization ruled by a monarchy that far back, but we don't know if the kingship was decided by the human world battle then or not. (ZBII ch.31)


Let me know if I overlooked anything else of interest. I wonder if, as the manga continues, we'll get more exact dates for a) Mamodo civilization's beginnings, b) the first invasion and the first contact between the Mamodos, books and humans, and c) when the kingship first started to be decided by the battles on Earth.
