Potential Plot Twist:
Turns out it was a Tornadragon (tornado dragon), which is a stage between drake and full dragon.
A drake is a baby dragon-to-be whereas a Tornadragon is a teenage dragon-to-be. So a Tornadragon CAN be purified, it’s just a lot harder. Luckily Sorey has two martyr-minded Squires to shovel excess Malevolence onto, so it’s a doable feat.
I’m stretching, okay?
