I don’t know my mc doesn’t know, but if he had any agency and resources to pursue any of his own project he’d try to find a way.
The only one I can think of currently is deliberately overloading the mana-ducts past the point of collapse. That would leave the mc completely without magic, but it would also force the parasites out or let them die because you cut their sustenance.
I don’t think the author is going to let the mc attempt that one except maybe as an epilogue choice.
The only other possibility seems to be the mysterious benefactor of the weird twins who seems to have a much deeper understanding of the parasites/phantasma than any current Arcadian, even Thalia. Though we’d probably have to torture such knowledge out of them, assuming the story will afford the mc such an opportunity. But maybe, just maybe they do know how to get rid of one too.
By Thalia’s own admission they do make the mc weaker. And there are more than a few hints that even normal magic use is particularly draining and unpleasant for the mc. For other mages using their powers seems both less draining and not unpleasant at all. And that can really only be attributed to the mc having to sustain three wholly and one mostly incompatible, draining parasite(s).
Thalia's admission on the mc's parasites
The priestess notes your pensive silence, but presses onwards. “Alas, for all that Mateus blood runs through your veins, there is not enough of it to sustain four phantasma; and so your mana ducts wither with each calling.” (emphasis mine)
So, yeah, my mc wants to get rid of the damned things as his highest goal at present, even if the immediate one is escaping new Arcadia. Of course now he has to sustain yet another one of the damned things.
Maybe hers provided a more passive boost, like the Wellspring one of the weird twins?
And maybe the mc is/was magically weak enough that she felt she didn’t need it and by the time mc is torturing themselves by using the only one of their damned parasites they can use it may have been too late for her to call on hers.
But my favourite theory is that hers is one of the more passive ones and may have just strengthened her normal magic use in some way since she takes on the mc’s Phantasma “ostensibly” on her own.
What always happens in the mc’s life. The spirit of Augur forces it on them anyway.
Yep, probably only the mysterious benefactor of the weirdass twins still knows that one. If we’re lucky.
Or maybe the mc could create one, given huge amounts or resources and decades of research, but that would at best make it an epilogue thing as much as the other desperate choice.
Well, not necessarily the mc was very much dead and it didn’t kill their parasites, unless they got resurrected along with the mc.
Also Augur is very much (un)dead, yet his phantasma is very much not.
So this again is something the present Arcadians seem to have at best a very feeble understanding of.
Therefore I’d amend this to the knowledge that in certain situations a phantasma can die with its wielder, but that certainly doesn’t seem to be a universal rule. The real question is whether the mc and Augur are the exceptions, or if the modern Arcadians have no understanding of the real rule(s), much like how some of our forefathers thought the Earth was flat and sun revolved around it.
