A long time ago, a large part of this world didn't have any humans. It was the heaven of different kinds of animals. To be accurate, there were two lands. One of these lands was led by cheetahs, the fastest animals in the world. Another land was led by Black Panthers, the most ferocious of all the leopards who were their underlings. These two lands met in one place, where a mysterious fire tried to reach the sky. People didn't dare come near these lands because of the leaders. But one day, two humans, a girl and a boy with hearts full of love, entered this no-man's land from opposite directions. They showered love on the ferocious animals and befriended them. The girl, whose name was Asman, partnered with the cheetahs and Agnee, the boy created a great relationship with the Black Panthers and leopards. The animals shared everything they had with their friends.

Both lands had gem mines that were extremely special and rare. The mine where the cheetahs resided had a kind of gem that looked like their eyes. It was a brown gem centered on a round black color. Asman named it Diurald. And the one guarded by the Black Panthers and leopards had a gem as a Black Panthers eye. A green eye centered on a sharp black color. It was named Nocturald by Agnee.

Walking in a straight direction, Agnee and Asman met one day, where the two lands connected. This place often emitted a mysterious green fire at night. Two humans kept staring at each other in front of the fire, under the sky. Agnee looked at Asman's curly black hair, which almost reached her toes, and beautiful brown eyes. Her soft skin was the darkest he could ever see. And Asman? She was dazed by Agnee's long, straight black hair and Emerald green eyes, which looked like candy floating in his milky white skin. They felt each other's heart and fell in love. As proof of their love, they soon had two children, a boy and a girl named Onho and Nishi. Onho was the spitting image of their mother, with the power to communicate with the cheetahs. And Nishi not only inherited her father's power to befriend the Black Panthers and leopards, but also his looks with a darker skin.

Soon after, people started to come here to live. The animals gave their leadership to the most intelligent being. Onho built the Diurnal Empire, and Nishi established the Empire of Nocturnals'. Keeping Agman, the place where Agnee and Asman met, in the middle, both empires kept growing proudly even after their deaths. People started to believe they could meet their fate where Agnee and Asman met.

The descendants of Onho and Nishi kept inheriting the power to partner with diurnal and nocturnal animals. But the number of black panthers started decreasing and was rare to be found. So the Nocturnals started to believe only the rightful heir to the throne could have a Black Panther by their side.

Time flew by, and things kept changing as the harmony between two empires broke because of human nature. The commoners couldn't do anything but wish for this harmony to be built again. Thus, a myth took place in both empires, like a prophecy. That said, "One day a child of either the Diurnal Imperial family or the Imperial family of Nocturnals' will renew the peace between them. And it will be a Nocturnal born in the Diurnal family or a Diuurnal born in the Nocturnal family."
