Spoilers for anyone who hasn't played/read this yet! (Nothing for chapter 7 tho)
I'm replaying the game and talking with Aster about the curse right after he saves you from the bandits, and I realized something. So we know that magic tends to follow a person, and not live inside them like it does our mc... but what if we can sort of expel the magic inside us? And when our curse tries to draw more in, we just expel it again? Due to how magic users work, we could still use it just fine, and we would get gradually more and more powerful too! We might even get to the point where it starts to increase our and any nearby people's lifespans! That is, if we can actively expel it to protect ourselves from drawing in too much magic.
side note, I get the feeling that our Mc is either a reincarnation of whoever that mysterious 10th God is, or maybe even a demigod of sorts? But whatever we are, it definitely seems to not be working correctly based on what we see from the prologue, which all of this even more interesting! 10/10 writing and plot!
Edit: I just realized something! So we know that Rune can heal people because she studied anatomy, so she can help someone's body put itself back together. So that got me thinking, we don't know much about how magic works for the gods, presumably, they just have it float around them like human magic users. But what if they store it inside of themselves too? Would they maybe have a different anatomy to facilitate such an absurd thing? And if so, even tho Rune herself said she can't grow back limbs or anything, what if Rune could help us grow said different anatomy, since we seem to have some godly magic as a part of us? She would likely have to study God anatomy, which would be quite difficult, but it could still be a very interesting solution!
