Dragonblood Warrior Shyvana was originally supposed to be the elemental dragon in Runeterra, not the elemental dragon in the game. Because she is the dragon egg laid by the elemental dragon Iva, in terms of bloodline, she should be a pure-blooded elemental dragon.
However, it was accidentally stolen by an ordinary human and was planned to be sold at a good price. But accidents always happen one after another. Due to human interference, the elemental dragon egg, the one carrying Shyvana, absorbed the person's breath and hatched early during the person's return journey, and the content inside was no longer there. It's a pure-blooded elemental dragon, but a purple-skinned humanoid baby girl.
The person who stole the dragon egg couldn't bear it, so he took the baby girl home and raised her, naming her Shyvana.
Many years later, the dragon Eva followed the traces and came to Demacia for revenge. Along the way, people were devastated and corpses were everywhere. The person who stole the dragon egg was also one of the many people who died. Shyvana saved her by chance. After killing the Demacian prince, it is possible that the current prince does not know how to EQ the second company. In order to repay his kindness, the prince decided to stay and fight against the irrational Iva together.
In the end, the dragon blood in Shyvana awakened, transformed into a dragon, and bit off the neck of her mother Iva. And took Ivar's skull to Demacia to receive the award, a proper act of motherly kindness and filial piety.
To sum up, the trafficker stole the child and was unwilling to sell him to raise him. Many years later, his mother came to find him and killed the trafficker. His daughter blamed her mother for killing the trafficker, thus killing her mother. And her mother happened to have a reward on her head. He took the initiative to sign the body donation certificate.
