Era of the Shattered World [3]

There were three major known eras; The Era of Sovereign Ascendance, the Age of Umbral Dominion, and the Era of the Shattered World. 

"The age of the Sovereign Ascendance dictates the age of the emergence of the Four Empires. The Aetheria Empire, Verdant Empire, Aurora Empire, and the Nurs Ancifa Empire." 

I read the contents of the book out loud. 

"It marks a relatively recent epoch, spanning only around 700 years."

So far, it was stuff that I was already somewhat aware of.  

"The Age of Umbral dictates the age of the Mirror Dimension expansion. Taking place approximately two millennia ago, this era signified the commencement of the struggle."

I skimmed through the pages and immersed myself in reading. The more I read, the more confused I became. In the end, this was a history book. 

It detailed everything about the past.
