Runes came from the remains of the gods.
Although they couldn't be described or recorded, becoming a rune-master required systematic learning in order to successfully meditate on runes in one's mind.
The rune world had developed for thousands of years, and there was already a systematic rune learning system, which was the Rune Academy.
Every Empire had a Rune Academy, and every year, the Empire would invest a large amount of money in the Rune Academy to Nurture rune-masters.
This was because rune-masters were the rulers of this world.
Different rune-masters had different abilities. Some had medical runes and possessed superb medical technology; some had elemental runes, such as water element runes, which allowed them to control rivers, lakes, and seas; and some had enhanced runes, their bodies were powerful, and their combat strength was astonishing. They could become outstanding warriors.
