Krysta blinked at him. "Yeessss," she said slowly, as though humoring a child, "and sometimes the river floods. A hurricane blows in off the ocean. Nature is destructive, but not out of malice. We also need it."
She frowned and shook her head. "Magic isn't some--some parasitic force against nature, it is nature." She thought furiously, trying to come up with a more concrete example. But the very idea of what he was saying was just...antithetical to her existence! It felt so obvious to her--she'd never had to defend it before.
"Oh!" She straightened up, fluttering her wings again with a smile. "Where does the new magic come from then? If it was really draining away at the world, we would see it, wouldn't we? Either the magic would start to dry up, or the world would. But it doesn't."
