In Godspring, there appears a winged girl.
"I'm not unwilling to try but there is the risk of making it more salient than it otherwise would have been -"
"Mixed strategy? Read their stuff to get an idea of how high risk they already are and how convinceable they'd be?"
"Sure, give me a dossier and I'll figure out who might be worth talking to. Or make one of my alts do it so I can make progress on the demons list."
His alts are asking Bar if there's a way to make arrangements that would let thousands of people request things from Bar at the same time.
That's technically a spatial problem, which is autohandled by the establishment, rather than a limitation on Bar's capacity. If they don't all need to be physically at the bar and people want to put ramps or a conveyor belt end or something on her she could provide things in response to prompts on a screen.
Great then they're going to try to identify all the worlds in the multiverse in desperate straits and if Tireh can figure out how to take passengers then she can jump to worlds, grab someone, bring them to Milliways, and thereby pause them. This is bottlenecked by Tireh having to learn enough things for an interdimensional jump so they'll only alert her to 'imminent destruction of planets' sized catastrophes, not mere genocides and so on.
They can spare someone to look at angels and fairies.
She'd like one of those memory necklaces to see how that goes. The blackmagery facts are usable but not that efficient and she has to clear them before they accumulate to anywhere near teleportation levels.
She can have a memory necklace. The Fëanors are almost done with an eidetic memory necklace, even. Can she use the same information repeatedly, learn a thousand high-value facts and forget them and then learn them again...
"So then maybe we should just find you the maximally efficient set of facts for a teleport, have stacks of paper with them written down, so you can learn them off a paper, burn it, and go..."
"Yeah, I should probably teach a couple other people how to do the thing so I'm not the only person who can, but the time dilation's mostly friendly and I'm immortal now!"
"Mortality is appalling and I'm very glad you found us. Has Nienna caused any horrible offense while tapping everyone in Beach -"
"That could be worse. The GCP is apprised of you guys, now. They're - mostly responsible, I don't think you need to be worried, though if you die they will be in a bit of a panic."
"Well, I don't have to go tempting sharks for my next lunch, so maybe that can be a while off."
"I very much hope so."
They arrange a screen to flash requests at Bar, a demon to do format conversions of the works she produces into something that can be disseminated electronically in Sanity, and a couple hundred thousand Elves with chiplocked computer installations to read, distill, write summaries, and identify worlds in urgent need.
Cam will have to open the door, since the address she was given was the Forks one.
James and Samuel are playing some kind of modified Quidditch-with-miniatures-as-levitation-practice thing under Fredrick's supervision in a corner (Mingling is watching), Michael is singing with Amriac in his lap, Minor is doing the format conversions and eating nachos, and Timothy is hovering protectively around Cam in case Niari has a comment. It makes for an eclectic little interdimensional bar.
Niari does, in fact, recognize Cam - and Timothy and Mingling and Minor, for that matter - but doesn't seem to know quite what to say.
"Hello! I'm so glad you could make the time. This is Milliways. The bar does excellent drink recommendations."
"Oh, my personnel are all back in Tirion, these are mostly students from the wizarding school in Hazel who're waiting while Hazel's paused."
