You wake up, and the fairy is right next to you.
Fairy: It has been a hard battle, you were about to die. No horrible, I have cured you now.
You feel weird, like your chest is burning. Suddenly, a flame escapes from your mouth... your breath is in fire. An egg of snake is right next to you. The fairy smiles.
'Fairy: Well, in order to save you, I brougth an egg of dragon, so you can receive the power of one. A dragonic snake entered into your mouth, and she has devoured your heart. Now she is your heart, and a dragon will be born through you
You look at yourself, the you see how flames begin to burn you out, soon you are only ashes, and a dragon (a giant winged serpent) is born from your ashes.
The dragon exhales flames and lava, the fairy is ecstaticly singing.
Yes, you are right. The fairy sacrificed you just to summon a god-like dragon. You were the sacrifice she was needing. But do not be so scared, you are still alive, but you are not yourself anymore, you are trapped into the heart of the dragon.
Fairy: Come with me dragon. There is a world to take over
