He needs to summon another demon, and he needs to do it fast. He whips out the Black Book, flips desperately through its pages, and arranges the offerings around the iron circle set into the floor of his basement. A phonebook, a pile of dust, a miniature casket, a oh my god he got in screw it he'll do it without the rest!
He forces an immense amount of energy through his body into the summoning. The dust whirls into the air. He screams as his skin crackles and snaps with static. "I summon thee! I summon thee! I summon thee, K-Kh-"
It is possibly the most regrettable sneeze in Mortimer Halliwell's life.
There is a plume of red flame, and there is someone in his circle.
"Was that very informative?"
"No, I just wanted to use the circle. Though it was good to know." He reaches into his backpack and pulls out a bag of sliced bread and a tiny plastic bear of fake honey. He applies the honey liberally to the bread, pushes the chair to the edge of the circle, and places the bread in front of it. Then he cups his hands around his mouth and whispers a name three times, too low for Morty to hear but possibly audible to the administrator.
"I want to give you this delicious honeyed bread," explains Ari.
"Why?! Why do you want to give me the delicious bread? Is it poison? IS IT?!" screams the faerie in a shrill voice.
"No. It is delicious. Eat the bread."
The creature's wings hum in the air as it weighs its options. Then it dives towards the delicious bread and tears into it like a starving vulture into a week-old gazelle carcass. It is a grisly sight.
Ari turns to the administrator. "Could you tell me if this sprite will go to an afterlife when it dies?" Before the sprite can begin screaming, he repeats, "The bread is not poisoned. It is delicious. Delicious things are not poison things." The fairy acknowledges his logic with a birdlike nod and returns to its gruesome meal.
"This creature belongs to one of the categories for which no afterlife currently exists."
He lets the sprite finish the interior of the bread, leaving behind the crust, then nods to it and releases it back to the Nevernever. He picks up the crust gingerly (it's soaked with glitter) and places it far enough away from the chair that he can safely light it on fire. "So, it looks like what we're working with here are souls," he says, once the bread is a pile of sparkly ash. "You wanted to bring the creatures who don't get an afterlife to exist in your realm when they died, you said?" He flicks his fingers in an impotent effort to remove the glitter. Pixie dust is even worse than craft glitter. He curses his luck.
He attempts to rub his fingers together and get rid of it that way. He fails. "Yeah. Pixie dust is like magic herpes, easy to get and impossible to get rid of. At least I'm not allergic."
She looks contemplatively at the pixie dust.
Now there is no more pixie dust in the room.
"Well, either way, I am eternally grateful for your services in helping me not have to stick my hands in a bucket of iron filings or spend the next two weeks scrubbing myself in purified water. Anyway, back on topic, are there any problems you can think of that would result from you... incorporating the soulless creatures into your afterlife?"
"I can't think of any. But it's possible we have different ideas of what constitutes a problem."
"Would anything become upset about it in this universe? Would the disruption of the natural cycle lead to some kind of energy drain away from our world? Would the fabric of reality split open and let in an unending sea of horrible monsters? That sort of thing."
"I do not anticipate any of those things. I can't predict who will or will not become upset, but I am reasonably certain neither the energy drain nor the unending sea of horrible monsters is a possible consequence."
"I guess... is there anything in this universe as powerful, or almost as powerful, as you are? Because if not, then them getting upset doesn't seem to matter much."
"Do you... have any way of contacting this entity? And asking if you can put the soulless into your afterlife? Because this sounds like it could turn into a death god deathmatch without much advance notice."
"I'm not sure," she says contemplatively. "I would like to avoid conflict if possible, but if I contact the entity and it denies permission, what is gained?"
"Point," Ari concedes. "But if it has some way of telling that the soulless are going to your afterlife and it wants to smite you for heresy or something, I feel like that'd be bad."
"It would be very annoying. Although it is strictly impossible to destroy me, I would not enjoy the attempt. Hmm. Of course, I also do not know how to contact that entity. I am disinclined to directly visit its domain."
"You could... huh. You could just appear a little engraved invitation to visit you in Morty's basement in front of it?"
