Thinking of making an AU of TBoSaS heavily inspired by Undertale in that they all have magic specific to their souls as well as districts. For example Lamina has the soul of perseverance and an ability related to plants. Treech has the soul of patience and can basically manifest axes he can manipulate and throw at people that sort of thing.
I was thinking of expanding on the soul thing too and just add more of them?
But anyways they also have this thing called “killing intent” basically this verse’s L.O.V.E. as well as the ability to hide it from others and basically flip a “switch” and go full on attack mode. It’s honestly kinda similar to how originally people thought Chara was the bad guy except they could all secretly be the bad guy here.
Honestly I don’t know where I’m going with this idea but figure it could be a cool twist to the recent magic aus I’ve seen on here. Plus… Undertale is lowkey my favorite game anyway? So overall just fits.
