I kinda want to see more of the magic side of the story tho... We know now with Serina that magic is broken enough to regenerate lost limbs albeit at a high difficulty so what could possibly be the limit for someone more gifted than her?
Oh and also magic babies :v
It's the usual IMAGINATION trope, where stagnation in life sciences, storytelling, and physics have led to a gap where an IRL human can excel with purely standard education and a bit of elbow grease. Or hand grease, in this case.
That being said, what Serina brute forced was horrifically taxing on the mind, recreating and activating every pain nerve in her hand. There's definitely still ways to improve on the process that Serina will never be able to do as she is.
