The Kingdom of Dragons was in the unknown depths of the Sea.
It was almost impossible to find the Kingdom of Dragons which was kept invisible by the Dome that protected it.
No one knew why the arrogant dragons kept their Kingdom hidden. Some thought it was because they didn't want to be troubled, but many believed that there was another reason.
The Kingdom of Dragons wasn't kept hidden because it was worried about getting attacked by other species within the sea.
Even the current King of Dragons didn't know why their city was hidden by their Ancestors. He had only heard that it was to protect the lifeline of the Dragons.
The current Dragon King didn't understand. In this world, they were strong. If they wanted, they could conquer the entire sea region.
So who could threaten their ancestors to the point of hiding the city?
The Dragon King simply thought that the Ancestors were too cautious for no reason.
