There’s so much going on here! It’s a complex, multi-layered cosmology with a lot of interesting ideas. The mix of sci-fi and fantasy tropes makes it feel fresh.
Some of the ideas don’t have a clear relationship to the others - the idea that divinities need belief doesn’t seem to fit with everything else, for example. But all the ideas have lots of potential - there’s so much here for a short jam entry! I can see myself using bits of it as inspiration. (The Resetter could be the basis of a whole setting all on its own!)
Some things are unclear which I think would help a GM make use of this. It feels like players would be Reachable Divinities (the analogue in this game of Nobilis’ Powers) - but are they meant to all be divinities of a single planet? Can they interact with the rest of the universe, or do they need to stay at home tending to their flock? Do they know all this information about types of souls and so on? The title and style make it feel like it’s written in character - it would help to know who wrote it, and who for. That might also help to decide where the detail goes - there’s lots of about Taúri, for example, but only a single mention of Diena.
I hope this useful feedback! I’d love to see a further iteration. I also really love the beautiful cover art - so great to see a beaming, happy face!
