LF fics similar to Bound in Servitude (protective bond dynamic, powerful Harry, complete)

Hey!

looking for fics similar to Bound in Servitude by Little Miss Xanda

I'm really into that whole thing where harry is magically tied to other beings (demons/creatures/familiars/whatever) and they’re super protective of him + get attached over time. doesn’t have to be literal servitude, just that strong bond where they’re basically his.

Looking for a harry who can actually hold his own too powerful, competent, maybe a bit sarcastic. grey/dark harry is totally fine.

Not really into ron/hermione bashing tbh. Some conflict is fine, i just don’t want them turned into complete assholes. I like when they’re still on harry’s side in the end.

any pairing is fine

PLEASE only completed fics, I am suffering at this point

(i know this one isn’t actually finished i just love the concept ok)

(sorry if i’m being too picky )
