The Master Necromancer - Vol 1 - Chapter 53

Skraal was just drinking in the inn all alone; there was nobody in the inn as a customer other than himself. He was just waiting for the time to pass. At that time, he started thinking about the years and the calendar itself.

It may not look important, but looking at its history, many things could be learned from it.

There are four eras in the world of "Grevola" (the real name of the world).

Lost Era: 0 to 10.000 Years

Magic Light Era: 0 to 5.000 Years

Cold Wind Era: 0 to 1000 years

Dawn Era: 0 to 3052

This means that the year is now called "Dawn Era: Year 3052."

Skraal knows the basics of every era and what happened in all of them.

The first era was called the "Lost Era" because many things of history, magical powers, and cultures were lost at that time. It is said that before the Lost Era, many people did not know how to write or read at all.
