I am randomly associating while searching for inspiration for a faerie related plot idea for a player character.
I am reminded of a rather trippy anime from a couple of decades ago, called "Revolutionary Girl Utena", where the protagonist accidentally gets involved in a duelling game of unknown Providence and rules.
The current duelling champion gets "possession" of the Rose Bride, a princess-like individual, until the current champion loses w duel.
This feels like it can be turned into a faerie tale, but in Ars mechanics would this Rose Bride be a Faerie Friend? Whose allegiance may change upon the outcome of the next unexpected duel?
Then again, princesses are captives of Ogres or Dragons. Could this be a curse imposed by the Rose Bride?
It seems possible to go too far with this idea.
How would an experienced faerie SG describe this?
With an evocatively otherworldly disregard for the mundane that borders on the numinous.
Edit:
I should call your attention to rumors of a mystery cult, both "visible and invisible," who seek the truth of chemical marriage of the Rose Bride and the Cross. Some even say they are the direct continuation of the Aphantos Agoge of the Olive tablets.
The thoughts attached to the real desire of the seeker will lead us to him and him to us.
Perhaps the Faerie is moderately powerful, but the faerie's story is that of 'The princess whose favor goes to the strongest in the land" - for this reason, she inspires and empowers them to fight for her and win her, and then immediately seeks a new target to empower and eventually overpower whoever has "won" her, while letting the current champion enjoy a few trifling fruits of her patronage.
Naturally, only after winning the Rose Bride's favor does the player discover that they've doomed themselves to an upcoming defeat, and have to find some way to extricate themselves from the Rose Bride before their rival (a previous NPC antagonist with a grudge?) strikes them down.
You could do this as a Faerie Friend Virtue coupled with the Greater Charm Flaw. The activation required for the charm would be whatever anime sequence you'd do to remind the audience that you're the current champion. And whoever defeats you in a duel would steal the charm (and Virtue).
