"Right, sorry. A Meister is a person who can wield a Weapon. Has the ability to resonate with a Weapon. Still following me?"

Spirit doesn't wait for an answer before pressing on. "For example, you could probably use me in my Weapon form. But it wouldn't be the same as if I were working with a Meister. With a Meister that has a compatible soul, we can...do more," he waves a hand vaguely, "like using soap and water. You can sort of use one without the other, but they're better together. And together, they make something a little bit different."
