I've been consuming just about any fic I could find, I'm sure there's more but here's my research notes: under the cut because I mention so 18+ stuff, vaguely but you can never be too sure
Young Nihil: fuckboi, garbage boy stinkman, most fics I read he's uhhhhhhh not very aware of his actions and therefore does dumb shit and comes across as insensitive towards other people’s feelings, needs and wants
Old Nihil: sweet old geezer, stupid but we love him, we do not fuck this man only ask for comfort and guidance with his sons
Papa I: old man, very into magic therefore spell work and things like sexy potions are things that come to mind for him, stern but loving -- where is all his content, kids?? [citation needed]
Papa II: harem plot, chosen lover, also old but has a zest for life (and bitches), has calmed down since III became Papa but still has expensive taste in both material things and lovers
Papa III: s l u t, y’all really love this man and there's a nice balance between wanting to top him and getting RAILED into the hell dimension by him, fun at parties, respects women
Copia: ratman, socially awkward with a hidden dominant side but mostly SUBMISSIVE, vague Gomez Addams vibes which I respect, heavier religious themes than with the others? I assume this has something to do with his recent ascension to Papa
werewolves but better? heat cycles and knotting are on the table as well as prey-play
Aether: Most on top of his shit, most human in his behavior and therefore very considerate of a human lover’s needs and physical limits, BEEF, nap on his chest, do it
Rain: Shy is like the default setting, but secretly like a daddy dom and really wants to fuck? I’m very confused by this [citation needed]
Mountain: Gentle giant, DONG FOR DAYS, doesn’t talk much but really doesn’t need to, (Ursula voice) don’t underestimate the importance of BODY L A N G U A G E HA!
Dewdrop/Fire(?) idk man y'all call him both: Goblin I relate to, craves violence, biter and marker, will fight you -- his fellow ghouls -- god himself -- anyone, needy as fuck
Swiss: Switch king, literal boyfriend material when you want him to be but feral if you let him do whatever, 10/10 would run into again in the middle of a desolated woodland
Cumulus: THICC, joined at the hip with Cirrus but I believe y’all consider her to be the gentler of the two? [citation needed] Even so, the Air Ghoulettes are not to be trifled with
Cirrus: Many fucking citations needed.
Mary Goore: a really rowdy boy, just a fun having fun-looking dirty boy, dead? alive? ghost? it’s all good times here! exhibits corvid behavior like collecting shiny’s and hanging around graveyards, blood kink
