Morty wasn't even trying to do anything this time. He was just fucking around with some cardboard, and okay, maybe it turned into an eldritch sigil of some kind, and then it blew up in his face, and now there's people in his room.
Herod's tail makes a swish thing. "As long it keeps him proper. We don't have a sense of what's proper in this universe." He plays around with his new shoes.
"Alright. Ariel's completely immune to cold, is why I ask," she explains conversationally. "The things that girl has worn out of my shop in the middle of winter..."
"Hey, you made that virgin-killer sweater of your own free will," Ariel says cheerfully.
"And that's something I must live with every day of my life," Ms. Rogers replies with a genteel shudder. "Oh, speaking of which, Gav, we should get you a couple of pairs of chaps. In case you have to unexpectedly ride a horse, or... something, I don't know your life."
"Riding horses or something sounds exactly just the sort of thing that fits my life."
Cecilia quickly has a wardrobe for Gav that she assures Herod is entirely respectable in many human cultures.
Ariel shepherds the boys out of the shop. "So, where to next?”
Gavriel is very glad with his acceptable-in-many-human-cultures wardrobe.
"There is more?"
"I don't know... writing supplies? If you want to get added to the reincarnation cycle as soon as possible we would need to prepare grab something to bleed Gav over-"
"Writing supplies we can get at the school store, so let's go into the woods until we're outside town limits and fly back to campus. As for 'something to bleed Gav over' are we talking more like a cauldron, a sacrificial altar, or what?"
"Nothing that elaborate. A jar and anything sufficiently sharp is enough if we don't mind getting messy, but I prefer something for blood extraction. The ritual will involve me painting some blood over myself and then over you and a bit on myself and then I will talk some introspective things about my relationship with my own magic while pushing it to power the whole thing. You will feel a sudden, but brief disorientation and acquire an empowering vice and the ability to use spellwords. Ah, doing this ritual means you won't reincarnate on Prime nor Tartarus in a future life, but the other worlds in the cycle will be fine."
"Oh, I can get you a blood draw kit. Does it specifically have to be Gav's blood, or is he just convenient? Because my friend Xan can make unlimited amounts of human blood for free."
"Either mine's or Gav's blood. As I understand it, it needs to be the blood of someone that is already part of the reincarnation cycle. It's sort of using our own magic to awaken yours, you see. Though, if we do it to Xan we could use him as blood source in the future."
Ariel floats up and pats Gav on the head. "I'm not sure the blood Xan manifests is meaningfully 'his' in a way the magic would respect, it's O- and he's B+. Doesn't match any specific person as far as we can tell."
Since she's already floating and they're now far enough out of sight of the town, she starts flying off towards the school.
They take flight. "It doesn't sound it wound work in that case. Well, Gav, it appears that you will need to spend a lot of time defenselessly tied to a bed."
"Thanks to modern technology, we can just suck the blood right out of your veins into a jar, then have my friend Sky heal you! No tying to a bed required, you can do that on your own time."
"Far be it from me to stand in the way of efficiency."
Soon enough they arrive at the store and walk in. Ariel snorts when she sees a blood draw kit occupying pride of place on a display table near the entrance. "Is it even legal to sell these here?" she wonders. She picks it up anyway.
Writing implements and Mason jars are easily found, along with all the toiletries and bedding they didn't purchase on their first trip.
Herod thank her profusely and he gets familiarized with the blood drawing kit. And the toiletries.
The toiletries are likely familiar: soap, shampoo, toothpaste and toothbrushes, shaving cream and razors, et cetera. The blood draw kit may be less familiar, but it seems pretty intuitive; there's a needle, a tube, and a bag.
"I'll handle the actual drawing," Ariel says, leading them back to Poe. "Seeing as I actually know how to use the thing."
The two demons can definitely recognize the functions. By their standards having soap and shampoo as two different products feels very like this place.
"Okay. I wonder if I should try being a healer here or not." They follow her back to Poe.
