Hello! Hope you are doing good, as well as your work on "Blacksmith" ^^ if that would be ok, I'd like to ask you a lore question regarding Apocalyptic Horseplay:
I am in process of making some fan characters to this setting, and one of them is supposed to have a deal with the devil, selling his soul in exchange for immortality; so the question is — can any demon have a deal with a human, or is this privilege available to Lucifer and Lucy only? And do they suggest deals in order to get something else with the soul, or the soul itself is enough?
Thank you for your answer in advance ❤
Alright, I think I can answer that. This will be specific to the UndeadEd/Apocalyptic Horseplay lore of course.
So first of all, only the Devil has the (formerly angelic) power to grant favors to mortals, meaning that any and all deals must be approved by him. Second, as far as Mr. D is concerned, the offering of one's soul is of notable value, but only if the owner of said soul was well on his or her way to be claimed by Heaven at the time of making the deal, meaning that any major sinner offering his or her soul in exchange for supernatural favors would most likely be denied (since their soul is already marked to be claimed by the Devil anyway). He might however make an exception if the favor granted by the deal is projected to impact and/or corrupt another more tantalizing prize.
As for the deals themselves, and while the Devil is known for offering luck, fame and fortune, the granting of actual superhuman powers (such as immortality or witchcraft) would require a LOT MORE than one's soul. The only way such a deal would be granted is if the subject is also vowing to directly and actively SERVE the forces of evil while on Earth, to be entrusted with tasks and missions that real demons cannot achieve, just like Lady Babel was tasked with serving the "Metatron" while acting as a double-agent within the Council.
In short, for one particular individual in this world to be granted immortality by the Devil himself, they'd have to be making themselves VERY VERY useful to him from that point on. Hope that helps!
