East Sea Kingdom.
The East Sea Kingdom was one of the many kingdoms into which the ancient and once extremely powerful Atlantis Empire had fragmented after the fall of the Forgotten Emperor.
Although it was only a part of something once glorious, like a mere fragment of a shattered mirror after hitting an impregnable wall, the East Sea Kingdom was considered a powerhouse even among the other kingdoms or fragments of the former Atlantis Empire.
Why? The answer was very simple indeed.
In reality, the East Sea Kingdom did not particularly have many Third Order soldiers and only had approximately 50.000 Second Order powerhouses at best. Furthermore, this kingdom was one of the ones that suffered the most in terms of population since they had a policy of attacking everyone even among themselves; a true jungle where sea creatures would not be safe even in their homes.
However, the East Sea Kingdom had recently gained a Fourth Order power.
