I was wondering about hagravens because I think it's quite well possible that the form in itself is a type of Hircine's therianthropy.
If I remember correctly, the glenmoril wyrd in Skyrim were corrupted into their humanoid ravenship by a hunger or thirst of power.
It wouldn't be that far of a leap in lore to think that it was Hircine who gave them this power, in exchange for sacrificing their beauty.
And it would explain why the forsworn (whom some are servants of hagraven matriachs) look like fanatics of Hircine with their armour.
It could also go to reason why hagravens / forsworn have a thing against aedra. In particular Kynareth's spriggans or Dibella's sybil.
So yes, I do believe we should have the potential for hagraven characters or cultists showing up in the RP, as well as unfortunate sport.
As in- random tamriellic figures or prey that have chosen to play a part of one of Hircine's many hunts. This would allow for a lot of variety.
