When he first arrived at the Chaotic Sea Domain, he was not alone.
A top-tier knight had defected with him.
The two were friends.
After mingling in the Chaotic Sea Domain for a few years, they found the archipelago where the merfolk currently reside and settled there.
Since they had traveled from the west to the archipelago, his friend decided to explore further east.
The two passed through a reef area and went a considerable distance before encountering a sea area shrouded in black fog.
In the Chaotic Sea Domain, bizarre geographical landscapes are countless, so he paid no attention and urged his friend to continue exploring eastward with him.
Unexpectedly, his friend took an interest in that place and insisted on going in to take a look, ignoring his persuasion.
As a result... he never came back out.
He tried various means to contact him, but to no avail.
