"I suppose your parents never told you what you really are, then?"
The wizard's eyes held a barely perceptible glow, beginning to gather some magic in the palm of his free hand.
"You are a dragonkin. A human who has been granted the power... and curse of transformation. The Dragons and Rulers of old made a pact of blood to combine powers against a common enemy. They call themselves the Dark Ones. They are a manifestation of the evil within every person. If someone becomes overwhelmed with negative energy, They can become a Dark one, part of a collective, evil conscious which seeks to conquer all the world." 
Taking the ball of magical energy gathered in his free hand, he held it out to the queen. "Take this. It will allow me to help you keep control the next time you transform. It will be painful, but once you fully absorb it, it will feel as if you simply hit your hands on something hard..."
He held back a silent tear, hating to do something as painful as this to someone he had known since they were but a crying babe in his arms.
