Era of the Empyrean Boar King!
It was named after the individual who entered the pinnacle realm and dictated the era's progression.
Sumatra Continent had a mechanism in which it could birth a mirror of its capabilities, the Empyrean Tentacle Race.
It was called its Blessed Race, and was born as three variants–the Iron Empyrean Tentacle, the Silver Empyrean Tentacle, and the Gold Empyrean Tentacle.
There can only be one of each on Sumatra. When one of them consumes the other two, it would become a complete existence and reach the Mystic Grade. That's when it becomes the Mystic Empyrean Tentacle, typically known as Sumatra's Blessed Race.
And whenever a Mystic Empyrean Tentacle is born on Sumatra, a new era starts.
The three variants could be born anywhere on Sumatra. Only once they consume each other will a Mystic Empyrean Tentacle be successfully born. This meant there were times of large gaps between two eras.
