Pack with the Devil
Edit: sorry about the earlier post, not too sure how that happened I've been typing for a while and hadn't noticed.
I've done my research on Wikipedia and such so I'd just like some feedback/constructive criticism. In my story the main character (#1 AKA Eivam) makes a deal with a devil, he gives up a portion of his life span and his soul in exchange for fame (he's an artist). Throughout the story several other characters make similar deals with the same demon. Now like all devil pacts there's a twist with each contract. My other titular character of the story, Imogen, she does a Dorian Gray style deal with her not aging and her portrait (painted by the MC#1).
In my story demons are creatures of change, bound by their masks to the underworld so the only way they can exist in the human world is if a human takes it off of them. Now for aesthetic, not to mention plot, sake assume human form. But being in the human world puts a strain on them, not too sure how yet probably either spiritual or physical, but they need to consume human souls and steal their life spans because people today live for too long (this story is set in the modern day in a fictional city in New York state).
So down to the meat of it all, devil #1 is Aeshma, based off of the demon Asmodeus from the book of Tobit and Aeshma a Daeva or demon from Persian mythology. He's a people person and plays the role of devil's advocate between protagonists and antagonists dealing with both sides but leans towards favoring Imogen and Eivam. Devil #2 is Mephistopheles, she is distant and more calculating than Aeshma, she favors my antagonists (Nina) because of what happened between her and Aeshma.
Questions: Is there a female form of the name Mephistopheles? (Taken from Goethe's Faust story) or something equivalent but not overly used, like Lilith, Morgan, (lol Dark Stalkers).
Does it make sense to give the demons this limit and the desire to ascend to the form of humans? And the need to extend their limited lifespan by stealing or accepting human souls?
Is there any advice you can give me, or anything wrong I can fix (beside the overly long post).
Thanks in advance
