do you think magnus could have survived the activation of the soul sword? or would his demon blood have overridden his angel blood?
That’s a good question! First off, I should clarify that Magnus doesn’t have angel blood at all; it’s specifically the blood of a fallen angel. A popular conception – which the books seem to hold to – is that fallen angels are responsible for having created the first demons. This means Magnus doesn’t have regular demon blood like other Downworlders, but something much more potent and closer to the source.
What’s significant about this – and this is something the books failed to explore – is twofold:
it suggests that your blood doesn’t define who you are no matter how little or how much “demon” you have in you
it suggests that downworlders and shadowhunters are really two sides of the same coin because everything originated from the angels; fallen or not, the seven princes are still archangels
As a result, I want to say there are certain things Magnus might actually be more susceptible to, including weapons specifically meant to destroy or harm demons like the soul sword because his blood is so closely aligned to the original fallen angels. Whether this is true or not ofc we don’t know, but I wish the show would consider it because it’s a good way of giving him a kryptonite without taking away from his power in silly ways like having a couple of vampires cling to his hands.
But I also think in his hands, he’s equally capable of wielding them, if that makes sense. Like, his fallen angel blood would have allowed him to activate the soul swordbut with different results than Jace with regular angel blood did, much in the same way that the witchlight glows red for him, not bright white.
But yeah! Basically I think it’s important to distinguish that Magnus doesn’t have angel blood like Clary or Jace because if he did, it’d undermine him as an example of someone whose birthright doesn’t define him; he’s specifically the son of a fallen angel/prince of hell and he’s learned to embrace his power without becoming dark and evil like his father.
