Thought of this bc @kitsunesongs's Fatherverse Lucilith (bc they're Addams coded) and Good Richard AU made me start thinking of stuff. Basically it's the mid 1920s and Alastor is from a branch family of the Addams Family, his parents are an interracial couple but that's ignored because Al's white father is LOADED. (And also a cutthroat lawyer that cops don't even wanna fuck with, given he has a 100% success rate and mafia connections.)
Anyways, Alastor's specific branch family has a tradition where every firstborn and every member who marries in must at some point in their life attempt to summon the devil. There's no expectation of success, because no one has ever succeeded. Both of Alastor's parents have tried and soundly failed. Alastor's grandmama and grandpapa failed. His cousins, uncles, and aunties failed. All of his ancestors have failed. The tradition is basically just a rite of passage members make to signify they are officially adults now, like a debut basically.
Alastor's a little late to the game, but for good reason; he decided to study every single ritual previous family members had attempted and even further study the devil and summoning circles. After years of extensive research, Alastor believes he's found the problem.
The same summoning circle was used for every single ritual, which, to be fair, it's not as though the circle was wrong. It is, indeed, the exact circle needed to summon the king of hell. Except, of course, Lucifer isn't the only ruler of hell. He has a queen. And, well, past translations indicate that at one point there wasn't an actual distinction between kings and queens. Lilith holds the same title as Lucifer. The fact that she isn't included in the summoning is actually quite rude, isn't it?
Unlike Alastor's ancestors and his immediate living family, Alastor tweaks the summoning circle to include the symbols of both Lucifer and Lilith. And he goes the extra mile by slow cooking the sacrificial lamb.
With a summoning ritual pulling at both Lucifer and Lillith at the same time, neither is capable of keeping the other from being called to Earth.
They're greeted by a very eager Alastor and a candlelit table with a massive feast featuring a whole slow-roasted lamb. Alastor is practically buzzing with joy at the fact that he DID IT! He summoned the King and Queen of Hell! He's basically proven himself the best magic user in his family line, SUCK IT COUSIN GENNY!
Lucifer and Lilith have a genuinely wonderful evening. They have a delicious dinner, Alastor was enthusiastic enough to play some piano for them so they had good music, and they're even given some privacy at some point with Alastor leaving them an enchanted bell to ring once they're finished.
Everything gets cleaned up and carted away by a household servant (a hunched reanimated corpse named Ghast) and Alastor is pleased to see that they enjoyed their night in the Magnolia Manor, ready to send them off back to Hell on a good note.
Lucifer: ... Hold on, what about the deal?
Lilith: Didn't you... summon us to make a deal? Don't mistake us, we're extremely pleased with how this summoning has gone so far, but surely your only priority wasn't to simply show us a good time, was it?
Alastor just sort of freezes for a moment, then almost hysterically mutters to himself "oh shit I completely forgot what summonings are for."
Lucifer: Hold on, you forgot?! How did you forget?!
Alastor: I don't— I mean, I was just following family tradition! Attempting to summon you is basically my coming of age ceremony, I wasn't thinking about the deal!
Lilith: So you don't have anything you'd want? You summoned us both, so you get two shots at this.
Alastor: I didn't even realize I had one, don't add more to this!
It takes a lot of back and forth, until eventually Alastor lands on two things he'd like that are within the rulers' powers.
Alastor: Alright. I don't really want to marry but my mother is dying for a grandchild, and our family's spells in regards to magical conception have long-term consequences that I don't think are worth it. So for my first condition, I'd like to have a child to add to my family.
Lucifer: *whispering* Honey I think the pretty boy is asking us to impregnate him.
Lilith: *also whispering* He's not but damn I wouldn't say no if he were.
Alastor: And for my final condition, while our family's money has gotten me and my mother out of quite a lot of trouble, it's not enough to truly ward off society from butting in and ruining my dreams in broadcasting. I'm not going to be unreasonable and ask you to end racism, I know that would be a task that never ends and would confine you to earth long enough to garner the attention of the heavens. Besides, we're wealthy enough that I could start up my own station right inside the manor. No, I'd like to evade censors. I know censorship laws will try to take me down, doubly so if my complexion is ever discovered. I want to broadcast exactly what I want to, and I want my content to reach those who will appreciate it. I don't yet have the spellwork to accomplish that, but I'm sure you do.
Thus, Alastor gets his perfect radio show without interference, and also, he gets a baby. In exchange for giving the royals his soul, of course, which is a fine deal if you ask him because he's reasonably sure they're not going to abuse it. Especially with how they're treating him and the baby...
He may have just magically procreated with the rulers of Hell. They keep calling Charlotte "princess." Hm.
Oh well! He'll deal with that whenever he gets to Hell!
After the summoning, he goes to find his parents to show off their new grandbaby and happily announce he managed to sell his soul to the King and Queen of Hell. He has succeeded in his summoning!
The entire extended family gets together to celebrate with a big feast, both for the successful summoning and to greet the newest member of the family.
