Hello, Lunari here for my first theory, and probably my only one for a long time. Quick disclaimer, since this is about my own idea, yes I do know the answer. The reason why I'm making this is a theory is because I don't know how else to do it.

So, let's start shall we? Let's answer a couple questions;

1. What happens to Lunari when she joins with another person?

2. How does Lunari lend her energy to another person?

So, first question. What happens to Lunari?
