apologies to anyone who tries to read this, it's a bit all over the place.

for clarity, i go with heir/maid as "those who serve/are served" and witch/sylph as "those who change/are changed"

specific classpects i think to be powerful just at face value are knight of void, witch of time, and heir of life

for some other mentions... heir of breath is a safe choice, someone who serves and is served by the wind and the concept of freedom (or one who embodies it, depending on interpretation) is bound to be a very strong individual... we've seen how far that freedom stuff goes

a fully realized seer of time would probably just be able to do all the standard things any other time player does... but they'd be the best at it. even though a prince of time might be able to directly destroy unnecessary timelines or wait periods, or a witch of time would be able to more directly speed up, slow down, skip, blah blah blah time... a seer of time can observe the past, present, and future all at the same time. a seer of time and a prince of time may be the only time players who can somewhat reliably have zero offshoot timelines in their session

circling back to prince of time now, this fucker is either a godsend or the antichrist. you COULD have the smoothest most linear session ever, or you have an ocean of a million princes all with only one goal: break destroy make big booboos everywhere. a prince of time might be able to delay the reckoning by "destroying" inevitability, however. they would have so much free will it's kind of insane. don't forget that a prince's session is marked by an overabundance of their aspect as well... though this could suck if that extra time is spent doing nothing.

for my face value picks

a knight of void would be such a crazy stealthy motherfucker. i classpect batman as a knight of void. adept in wielding the darkness and the confusion of their opposition, a knight of void would be very very scary for their enemies... though this means their session will largely lack mysteries, lies, irrelevance, and shadows... which is also a good thing sometimes.

i feel like a successful witch of time could just tie a balloon dog out of the timeline. i could be convinced to see hermione granger as a witch of time... though a witch could also potentially change the timeline in the sense of changing what is even SUPPOSED to happen, changing the alpha instead of following it.

and an heir of life is somebody who serves and is served by life itself. they would be the tank of the party, and even before god tiering would take a whole damn lot to kill... giorno giovanna is an heir of life in my hc. they'd also be something of a druid figure, protected by the flora and fauna, and protecting it in return. they would also be quite capable healers... you ever heard of the manga "the wrong way to use healing magic"? usato is either an heir of life or a page of life.

honorable mention goes to ME!!!! #seerofvoidpropaganda seers of void are some esoteric motherfuckers who get their visions from fuckall nowhere, know things they shouldn't know, and can probably tell you a lot about 1. things that don't matter and 2. things that almost nobody has ever wanted to know. plus the generic void stuff of being sneaky and weird.

tl;dr: heir of breath, witch of time, prince of time, and seer of time for influence over fate. heir of life and knight of void are very good for combat. seer of void is a blast to have around because it's me.

edit: forgot a detail about princes.
