The dragons were the origin of all magics. Draconic was the best language to communicate with elements. Draconic characters could record anything with just one symbol. The symbols were full of magic and only those who met all the criteria set by the writers would read the information. Every adult dragon would have their flowing island that travels through the land or ocean with their will.
To the people of the land, the dragons were a living miracle, a messenger of God. So they worshipped and believed in the dragons and recorded their wise words into “The Book of Dragons.”
And for dragons…
『THAT’S ENOUGH! You impulse fools! How many times do I have to tell you humans are weak. Our tails could batter hundreds of humans to death, and you fools put a forbidden spell at the wild human preserve! What? You try helping your beloved human to fight? That is enough! Because of us, the human civilizations have been destroyed for at least five times, FIVE TIMES! No more excuses! From now on, any dragons who did not obtain a level six certification in Human Language, a level five certificate in Human Transfiguration, or a level four certificate in Human Conservation will not be allowed in the Wild Human Preserve! THAT IS IT!』
