also remember we didn’t enslave the Succubus, we made a deal with her and are in a mutually beneficial contract because we offered her the hearts of 3 good men
the deal is we will keep giving her the hearts/souls of good men in exchange for service
likewise the imp and fel imp are in a contract, and the felguard likes working with us, etc
Only demon that was enslaved properly was the Felhunter, who is a dog, ie felpuppy
