Sounds like you're about to add a large chunk of lore to the story.

In my eyes it's not much more than I added with the spirit realm. For all intents and purposes I'm basically just making more NPC groups. The underworld itself might be getting fleshed out, but since nobody else seemed to be going that route with their Keepers I figured doing as much wouldn't cause any contradictions.
