A long time ago, when the dragons started to use the dragon sword magic, Dragon King ordered the dragons to teach the dragon sword magic to the people.
Because Dragon King knew that the Dark Dragon was also going to attack to the lands of the humans.
That's because the dragon knights got trained by the dragons and prepared to fight against the Dark Dragon.
But Dark Dragon done something unexpected that the dragon turned into a sword and the dark emperor started to conquer the ancient empires one by one.
At the start of the war, there was a battle that was one of the most important battles at the time of the ancient empires. Dragon King fell down at the battle and dragon knights withdrew as the dark emperor started to win the battle.
When the Dragon King fell down, Dark Dragon believed that the war was over.
But the war was far from over since dragons and dragon knights still fought against the dark emperor and tried to protect the empires and the maze.
At the end one dragon knight took down the dark emperor at the maze and the battle was over.
At least that was what everyone thought.
