"That's not how possession works in my world. A spirit can simply enter the body of a human. Usually through the head or heart," he said as he lifted a hand to cup over his heart, where Raava had passed through him so many times. "When a spirit enters a human, they usually cause physical changes. Permanent ones. If the spirit leaves before the human dies. The changes make the human appear more like the spirit that possessed them."

This was not something he'd told anyone from his world directly before. He'd never really gone into the details of it or put much thought into it. He knew the first time Raava passed through him that he might end up with tentacles of light growing out of his head or his legs fusing into a tail. And despite knowing that, he hadn't thought twice about allowing her to do so.

His eyebrows raised at the question, though, and when he answered, he didn't think twice about that either, "Completely."
