In the continent of Vie, there were 2 opposing factions of Human. The Lait and Rait.
The Lait consists of those that followed the teachings of Yeru the Wise. He is believed by the Lait to be "One who guide". They are a somewhat pacifist faction that doesn't interfere with the worldly affairs and focused on their own selves. Yeru teaches how to be one with the nature, care for each other and not treating other individuals like how you don't want to be treated.
The Rait are those who rejected the teachings of Yeru the Wise. They think that Yeru is a bad influence to the world and believed that the world should move by the desires of beings living in it. Acting as a sort of background for the characters.
These 2 factions are the foundation for the era of enlightenment where people start to expand their knowledge on things that are previously unexplored.
Until someday, the daughter of an elder in the Lait faction fell in love with an ordinary squire from Rait. They meet in secret, talk to each other and slowly grow closer together. The daughter eventually got pregnant and conceived a pair of twin. A boy that is born right where the sun shines the brightest and a girl whose birth conjured shadows around the area she laid.
The twin are seen as something miraculous as the phenomena that occurs after their birth is nothing short of extraordinary.
The boy will eventually be living most of his life with The Rait. It is said that his influence changed the way The Rait operates and making them more tolerant of The Lait while also having more thirst for fights that are beautiful.
The girl is taken by The Lait and was dubbed as the second coming of Yeru the Wise. She's kind, brave and friendly to anyone she meets. Like her brother, she is influential in The Lait and
Things were peaceful in the Vie Continent for 17 years after the birth of the twin until suddenly, black clouds start to form around the continent. It is said those within it are lost, never to be found. Seeing the dire state of the continent, the Twin rallied their respective faction and went to the area where the clouds are gathering. There, they met with a creature that has a pair of horn on their head and wings on their back. They introduced themselves as Daemon and were transported here from somewhere else after their whole race was at war. They told the humans that this cloud is caused by a friction of mana between their leader and another race leader as they tried to subdue the originator of the black clouds.
The black cloud is caused by the Delkin. A race that sought for enjoyment on other's misfortune. And Daemon just so happened to be their target.
After hearing this story, the twin teamed up with the Daemon and fight together to clear the black cloud once and for all.
Along the way, they met other races that are transported to the continent of Vie, like the Nature-Loved Elv, Battle-Hungry Rais, The Emissary of God Yuloo and many more.
Eventually, they managed to create a grouop consisted of the most skilled and talented members of races in the Vie continent and drive back the dark cloud. This will be remembered as "The Unification". Where the races of Vie continent unified for the first time for a common enemy.
This also start the new age of enlightenment and the members of the party that drive back the dark cloud will be known as "Family Heads". All 15 of them are the first recorded "Transcendent".
