During Nari's tribulation, a dragon lady appeared, demanding that she take a new blood essence that would revert her back to the path of a Great Calamity, something they so desperately wanted.
Nari, of course, rejected her offer and killed her.
However, the being that appeared back then wasn't that powerful. It was a sliver of the true form of the lady.
But the one standing before Klaus is a true pink dragon—a real dragon extending a whopping 400 meters. The mere sight of how colossal it looked made Klaus wonder just what the heavens wanted to do.
Suddenly, the dragon transformed into a young man, taking on a handsome, pink-haired human form. He's about 7 feet tall and has two pink horns on his forehead, slightly scaly hands, and sharp claws.
"My name is Eldrin. I am a messenger from the heavens sent to punish you," the dragon man, Eldrin, said, looking coldly at Klaus.
