"You really are an oddball. When humans are hit with that spell, it is supposed to transform them into a type of Demon appropriate to their power level, with an appearance that reflects the very worst aspects of their nature.

"Use your new magic and see what happens. It's better to get it all out of the way at once." The pity was clear in her voice, but she had a point.
