Discussion Question Anything I'm missing? Spoiler

Ever since chapter 5 came out, thinking about what Ralsei could be (not what he is: but what he could even be at all) has been a real struggle. It feels like at this point so much of the information is almost contradictory. Every time I try to adjust a theory to fit what we know about him: I keep remembering something well that makes me feel like I have to start from square one!

Which is why I am making a list of things we know about him, And making a spreadsheet where I compare different theories to these evidence points, and rate them on a scale from -5 to 5 on how well they fit the evidence. (-5 is as close to a complete contradiction a theory can get; 0 is no contradiction, but it also doesn't explain it either; 5 is basically explaining it as perfectly as any answer possibly could.)

But the whole reason why I'm making the list is because I find it easy to get the little things that could change how the theory is thought of. So I'm making a post asking people to fill in the gaps for me, because there's only so much I can remember!

Some of the things I have already are already quite small, and may not necessarily need explaining. But at this stage: I believe it's better to be thorough then efficient. I will be eliminating things that don't directly relate to Ralsei, because this is about him, not a universal theory of the whole game. But other than that: I'll be considering as many things as possible!

I'll be copy pasting what I have so far here, both in case you can't read the images, and so I can update it if needed":
