It'll take some explaining, but I'll try and give the easy version. Basically, you've got the world that you humans know — we call it the Near Shore. And then there's the Far Shore, where gods and spirits and Phantoms live. We can interact with you guys, but for the most part, humans don't have a spiritual sense, so you can't see it. Phantoms... I guess it's like they feed off of negative emotions? So bad energy tends to attract 'em, and then they make it worse, and then... well, you can imagine.

[ It's bad news and people do shitty things. ]

So gods like me slay 'em.
