Crimson's geas here is really interesting, and provides some interesting conflict. It's also interesting that the fae can apparently bypass their pretty potent magical protections and lay down a long-lasting curse like that, in terms of the broader setting.
Eh, specifics can certainly vary a lot by setting, but generally speaking, fae shenanigans tend to run in the vein of only really being able to have power given to them. It's common for that to involve trickery or misunderstanding, but I would be inclined to suspect that in Crimson's case she technically agreed to it. If that is the case, well, magical protection doesn't tend to amount to much against something let to happen. That may be all the more applicable, too, when strictly speaking the geas in and of itself isn't anything harmful, entirely "fair" from a certain point of view.
If it's shipping over a new body, it raises the question of why killing her with dark magic makes the rez take longer.
I have to wonder if using dark magic might actually accomplish a measure of actual harm to her. She comes back after being killed as what seems to be a standard staple; in a setup like that, for a fantasy setting, heck, that kinda raises the idea that the go-to solution ought to be to break out the necromancers to try to make death stick... and maybe that's not far off what's in play?
Her physical form is basically irrelevant by all accounts. Do something to her physical form, and it's basically meaningless because that's more or less her relationship with her body in the first place. So, gotta do something to "her", personally and directly, not just the interchangeable meatsuit. If dark magic, say, means some kind of mumbo jumbo magic stuff harming her spirit or the like, that could be more meaningful than obliging her to just grab a new body.
Clearly, dark magic isn't enough to cut it as such power has been employed thus far, but it suggests a possibility that her adversaries might be on the right track. Perhaps she has to rest up and recover from getting actually hurt, and perhaps so much killing her a whole lot harder with more potent dark magic might accomplish more.
Come to think of it, though, the fact that she takes seven months and a day to come back from being killed with dark magic compared to merely a few days of downtime otherwise makes me wonder if maybe she's having to "actually resurrect" resurrect. The other girls demonstrate that pretty serious injury, well,
isn't, not to them; it's a running joke that VV keeps breaking their bones, and yet the Rainbows are aggravated and exasperated by it, not in traction. And Magenta is apparently an old magical girl? Maybe she has picked up a fuzzy relationship with what mortality and what counts as alive and dead in her years. Perhaps mundane death is sorta just a serious injury to her yet within the context of how bad "bad" is for a Rainbow? Yet if she's slain by dark magic, maybe that's a whole different story requiring much more involved recovery to actually come back to life from something much more definitively dead or at least not-alive?
Regardless, though, it is interesting that she has been around so long. The timescale we've been given is a little ambiguous, but unless gargoyles happen to have unusually short generations so that the comment about Gray's grandmother doesn't actually mean much, well, it does certainly suggest that Magenta has been a staple for a good long while. That, coupled with the peculiarity of her different recovery times and the current setup makes me a little suspicious if maybe Magenta herself isn't necessarily responsible for her resurrection; if it's seven months and a day for her to come back after death by dark magic... maybe she has a backer that isn't
letting her die a true death?
Given that VV is tight with a dark goddess and Crimson establishes that geas shenanigans and Faerie exist, I'm definitely not ruling out the possibility for Magenta to be complicated.
And considering the mention of changing VV's eye and hair colour, I'm kind of wondering if Joy would reverse those changes as part of 'revealing her presence'... Just for that extra bit of chaos.
A thought, would Joy necessarily need to do so? Crimson's perspective piece reveals a lot about the Rainbows, and from what the chapter puts forth, it looks like "Violence" and "Violet" can perfectly well be two distinct physical forms that needn't necessarily have much bearing on one another. If VV transforms, the fact that Joy changed her original hair and eye colours may be irrelevant.
Granted, given that Joy was responsible for the disguise change, it still wouldn't be surprising if actually it totally did matter anyway, but I'm inclined to suspect that going full Rainbow Revolutionary could make blatant her place in the lineup.
