@DixonUranus They could just wait for a sequel of HL where it takes place after Voldemort defeat, Hermione becomes an auror and does activism to give "near human intelligence" magical creatures in the wizarding world equal rights to wizards.

But the game takes place long before the events of Harry Potter books, when the theme of Slavery with house elves was already a thing. Fuck these NPCs, they always find a reason to bitch.
