how do you think a character that switches from being an heir of doom to a muse of doom would work?
i've never considered something like that before! :0
imo, a switched classpect would usually never happen in a normal session. of course, the situations for switching a classpect before the session happens is different, as characters tend to be malleable and grow over time.
i'll assume you mean in-session, though, which creates a really interesting situation. especially with a switch to a master class. i would say a heir ==> muse switch would be possible, since the master classes, especially muse, embody their aspects in a similar way. this would also require a strong personality shift, very likely caused by trauma or an extremely impactful event in this character's story.
i could see an heir of doom being someone mostly consumed by their own suffering and the suffering of others. empathetic, and a good commiserator, but a major downer. a muse is much of the same, consumed by doom, but while heir would be more of a container of doom, keeping it inside themself, a muse inspires their aspect into creation and existence. and with the more literal interpretation of doom as the death aspect, well... i could see this as a spectre of death type figure, in both forms.
this has great potential for a morally grey/ questionable character as well! muses, despite their passive nature, are not guaranteed to be good people, after all.
thanks for asking in!! if you have more questions, be free to ask and i'll gladly elaborate ^U^
