==Prologue: Young Duos and the Dragon Egg==
At the age of 15, young Duos was a talented swordsman, a intelligent strategist, and a dragonologist who study dragons. But his abusive father Lord Dagger hates Dragons being a hired Dragon Hunter with gold in return and enough muscle to brutally teach his son a lesson, he made one rule in mind, no dragons in his castle.
It wasn't long until Duos stumbed onto a underground cavern which is where a dead dragon mother who died protecting her unhatched child in its bone claws. Duos took the egg and said, "Don't worry little guy, I'll protect you."
After 3 days of secretly taking care of the dragon egg, his father finally figured out Duos' secret after smelling a dragon's stench. Both father and son fought with swords and after getting scarred in the right side of his face and before getting stabbed in the heart. The dragon egg hatched into a small orange dragon and breathe a stream of flames called Flamethrower and incinerated Lord Dagger. After they are safe, Duos took a look at his face, the scar came from the right side of his forehead, across the eye, not blinding him, and ended at the chin.
"You know something, the two of us can make a good team, though nomadic but free to roam the open world," said Duos, "But first, I need to get a armor."
At the Blacksmith's shop belonging to a Dwarf named Doralph, Doralph took a look at the height and weight of Duos and forged a armor that suspense age at a certain point, stronger and lighter than titanium, and a purple clad paintjob. He calls it the Violetine Armor.
Also, Doralph made Duos a sword made out of Netherum which withstands dark foes' attack and can make fast strikes.
After 6 years battling monsters big or small, they became a unlikely duo turned heroes of Radius Kingdom.
"Hey boss, what's next," said Dracon.
Then flying above them is a squadron of Ape Dropships and Fighters heading for Palace Radius.
"Looks like we're heading for Palace Radius," said Duos, "You're ready."
Then Dracon changed size into a adult dragon and said, "Always"
Duos mounted on Dracon and both of them said their motto when Duos mounts on Dracon, "When Knight and Dragon Combines, No Evil Shall be Victorious."
They flew towards Palace Radius and begin a legendary adventure unlike any other.
