@tokensane @rpg In my setting magic is superscience left over from the first age. Could be nanites in everything, could be something weirder. The players casting spells is similar to if your dog figured out how to say "Alexa, all lights on" and realized saying those magic words created light.Also, the aliens are going to be demons, sort of, being the children of the Fear of the Other and the Fear of the Incomprehensible. Not that the aliens or PCs would know this. So magic will work fine.
