I like them all quite a bit, tbh.
Revendreth stands out to me as the only one that doesn’t feel quite heavily inspired by a particular class fantasy. Night Fae = Druid, Kyrian = Paladin, Necrolords = Death Knight.
Revendreth = Vampire Aristocrats, I guess lol.
So it’s a little different in that sense. I like their crumbling castle and the somewhat absurd quality of the whole dynamic.
But it’s not necessarily my favorite. Night Fae is fantastic, I like the Kyrian aesthetic. I don’t have a character in Necrolords yet, but I’m looking forward to my next character choosing it.
