To start with, there are now eight Bells. Pattern isn't bringing anyone besides herself, and Aegis no one besides herself and her Whistle, but everyone else -
Between Alice, the Joker, the rescued Queenie, Kas, Micaiah, and Sue, plus Ghosty who Amariah picked up on her way home, that's seven Whistles. (Stella thinks ahead: there is a soundproofed orgy chamber away from the main party awning. With a few nodes off of it in case more than one orgy forms; she can think of at least two other likely ones.)
There's an equally absurd number of Sherlocks and Tonies if you count them together. They have Juliet's matched set, Shell Bell's matched set, two other matched sets from Bell-less worlds (one with souled vampire, one both human), a stray Tony, and a stray Sherlock from Downside.
Amariah grabbed a random Libby on top of the random extra Whistle, but at least she's not incorporating anyone from home.
Golden's bringing much of her family and many of her friends - although Edward is staying home, that still leaves Elspeth and Jacob, Alice and Jasper with little Brandon, Rosalie and Emmett and little Henry, Nathan accompanying his mate and their child Kerron, Esme and Carlisle and their Lily, Addy, and Elena who'll get to see her brother. Golden claims that this is a conservative list and she could easily have produced another twenty enthusiastic guests. Stella doesn't doubt it. She puts up a few signs reading Please Conduct Adult Conversation Only Via Brainphone. Little Half-Vampires Have Good Ears And Perfect Memories. As a last-minute surprise, Golden has taken Elspeth's suggestion to bring Edward's deceased mother Elizabeth, too.
Juliet has, on top of her boyfriend and his - progenitor? - her tiny Libby, James, a tagalong thereto called Virginia, and a ghost called Minnie, plus Giles.
Angela's list is more modest: her, her husband, and their friends Alleluia and Caleb.
Shell Bell is responsible for half the Sherlocks-and-Tonies all by herself, a tagalong called Pepper, and also someone called Darcy and also Matilda. (Shell Bell is also the reason Angela is not inviting her brother-in-law.)
Stella herself is responsible for inviting Libby, Orfeo, Chris, Mary, Anna, Sandy, Eights, Chainsaw, Lazarus, Kolya (who is informed that it would be awfully inconvenient for a majority of Bells to all have to coordinate on pretending he doesn't exist when only one of them has even met him to be able to identify him in the first place, so he can simply stay home if he's planning to be hidey), and Bridget.
Stella sets up a name tag system. Everyone will have a tag stuck to them. Solo persons - a minority - will just have their names. People with template names and nicknames will have both stamped on automatically. ("Hi! I'm a Bell, and you can call me Stella!"; "Hi! I'm a Whistle, and you can call me Alice!" "Hi! I'm a Sherlock, and I don't have a distinguishing nickname yet but as soon as I pick one it will appear here!")
She conjures up a nice buffet of food and beverages which will stay its correct temperature until consumed, and assorted synthetics for the vampires (labeled not for human consumption), and dishes and flatware (all glass; even some of the food-eating guests might dissolve anything else) and fusses with the awning opacity until it lets in just the right amount of sun, and, what the hell, she throws in a stage in case Angela wants to sing or she decides to play the flute or someone decides to pentagon some other performative skill to entertain the crowd. She makes sure there are enough bathrooms for all the people who still need bathrooms.
She puts out a few tables here and there with little bowls of squares and triangles - a mix of her glowing red and Alice's shifty black - in them for everyone's convenience. She accumulates coins in those sizes faster than she generally uses them and has a great many, so there are plenty for anyone to dip and wish if something comes up. She double-checks to make sure the Martian ground rules prohibit any misuses available for those size coins.
Jane gets one of those high-tech holographic projectors, on wheels, which she promptly manifests in, drives around the floor, and makes faces through.
Libby shows up next. "You know," she muses, "this probably means I'm never going to be your favourite grandma, doesn't it. Too much competition."
"Were you ever going to be?" wonders the next Libby, whose nametag declares that she has not yet picked a distinguishing nickname.
"Fine," she sighs. "How about Slipstick."
"And I can be Granny," says Elspeth's grandma, "since I'm apparently never going to be known for anything else."
"Sure. Besides Mama and Stella and Juliet, there's Shell Bell, who's already taken over Atlantis and was the one to discover Downside by getting assassinated. There's Amariah, who's a witch and lives in Alethia which is the only world we know about that isn't attached to Downside now and everybody there has an external usually-animal-shaped soul and it's contagious if you go there so that's something to consider, and she has an artifact that dispenses objective truth but only within Alethia, and she hasn't taken over yet. Angela hasn't taken over either, because she lives in a theocracy and even though it turns out the god is a spaceship and not a real god she's waiting for the last Archangel to finish out his term - that's her, up on stage, with the other angel, I think they're going to sing! And there's Aegis who's from the future, maybe not as far as Angela but we're not quite sure about Angela's history, and she's younger than all the others and she's an admiral and she got a hostile alien species to surrender and last I heard she was going to see about getting democratically elected to be something called Hegemon. And there's Pattern who is called that because she has no distinguishing features yet."
"Interesting," says Slipstick. "Sure, I could lend a hand there. If she hasn't already got one by the time she leaves the party."
"Well, two kinds of it," says Elspeth. "Stella's precog Mary has been helping with the wolves, and now that Aunt Alice has cleared up her blind spots she can do it herself - and she was already keeping a lookout for problematic instances of the vampire version."
Elspeth pats her wolf on the arm. "So he's my bodyguard, although the title is less essential now that we've got wishcoins going spare," she says. "Mama barely uses hers anymore except when she's at formal meetings with human governments and wants to be shadowed by an entourage."
"Are you going to drag yours out of storage?" inquires Slipstick.
Granny nods. "Soon. And your mothers?" she asks, looking between the rest of her template.
"It's on the to-do list," says Libby.
"Mama had a harder time of taking over our world than the other Bells have had with theirs, because she didn't have coins, just individual people some of whom had witchcraft, and because someone was already ruling the vampires when she got there. One of her plans backfired and she and Dad wound up each thinking the other was dead for five years, and mated vampires can't really do a lot without their mates safe. Mama managed to bring me up while pretending to be dead to everybody else she knew, which is more than most anyone would have been able to do. But then we got split up and I found Jake's pack of wolves and the Volturi found the pack and I found Dad being kept prisoner in Volterra where the Volturi ruled from, and a lot of very complicated things happened but eventually the Volturi were defeated and Mama became Empress."
