"Sort of like we view the weather, really. Wind can pull your aravel and it can damage it. That there is wind isn't a good or bad thing, you just have to be aware of the state of it and shorten sail when it's too strong. Spirits and demons aren't fundamentally different to us. They're all equally dangerous, just like a little breeze can become a gale. And we don't know what else to do about possession except to kill or be killed."
