“So You Want To Be A Wizard?”

“Virtue," he said. "The real thing. It's not some kind of cuddly teddy bear you can keep on the shelf until you need a hug. It's dangerous, which is why it makes people so nervous. Virtue has its own agenda, and believe me, it's not always yours. The word itself means strength, power. And when it gets loose, you'd better watch out."Something bad might happen..."Impossible. But possibly something painful"-A Wizard Alone by Diane Duane”

“Something always happens. You still have to promise stuff anyway. If you have to work to make the promises true... it's like a spell. You have to say the words every time you want the results.”

“The city breathing, burning, living the life thy had preserved. Ten million lives and more. If something should happen to all that life- how terrible! Nita gulped for control as she remembered Fred's word of just this morning, an eternity ago. And this was what being a wizard was about. Keeping terrible things from happening, even when it hurts. Not just power, or control of what ordinary people couldn't control, or delight in being able to make strange things happen. Those were the side effects- not the reason, the purpose.”

“You do have the idea of being ‘just good friends?’” He gave her a sideways look. “For so high and honorable an estate,” Roshaun said, “ ‘just’ seems a poor modifier to choose.”

“What are you thinking of? Dairine demanded. Let me help you— You need to stay here and let me do this, Roshaun said.But if I can just— You can’t, Roshaun said, looking at her with that infuriating, amused expression. But then that’s what “Guarantor” means. If the world can’t pay the price…if the people around you can’t pay the price…you do. The price? No! Dairine said. No! You don’t even like my little planet—you said so— No, Roshaun said. Which is possibly the best of all possible reasons to do this. He stepped out of the wizardry. “No,” Dairine whispered. “No! Roshaun!” Roshaun vanished into the fire.”
