Mm, more or less. It is not strictly necessary, but I enjoy doing it sometimes. It is a stress relief, in a way. [setting things on fire, for example, is a great stress relief. Though she doesn't do that nearly as often, and certainly won't do it here]

It sounds a bit similar to magic, but . . . is it something someone must hone as well? Or is it something one learns and has no need of further practice? Though it sounds more the former, if there are so many lessons one can learn.
