One lovely afternoon Miles gets a rather urgent call from Ivan.
"...I see," says Miles. "So - sorry, let me check if I have this right - there's a bar, and the bar has a door, and the door goes lots of places, and it was supposed to take you home but instead it took you to where my cousin Ivan found you, and you don't know why?"
"Well," he says, "that would explain why I haven't heard of it. That's... troublesome. If it were only a matter of getting you back to the right planet, it would hardly be any trouble at all. I'm not sure where to start when it's a matter of getting you back to the right - universe? Do I have that right?"
"Well," says Miles. "There's not much opportunity for a little girl with wings to fly around here - crowded city, controlled airspace - but my family happens to have a house by a very nice lake that I think is pretty good for flying. Want to go there and see what you think of it?"
"There are a lot of people on Barrayar who get very upset about people who are strange-looking," says Miles. "I'm short and a little bit weird, and if I go walking in the wrong places, people will try to bother me like they were bothering you before Ivan showed up. Having wings is a lot stranger than being short, so more people get upset about it. If you hide the wings, people won't notice them to get upset about."
"My lightflyer's on the roof," he says. "For flying to the lake house in. We can get up there in the lift tube at the back of the house. Do they have lift tubes where you're from?"
Here is the lift tube! It is big enough to comfortably admit traffic in both directions, but not big enough to fit Pen's full wingspan. Miles steps inside, adjusts casually to the transition between gravity and its absence, and catches hold of the safety ladder to propel himself upward.
He studies the interior of the lightflyer for a few seconds, then goes in and starts tinkering. A half-minute later, the back of one of the forward seats has been detached and secured in the rear seat, leaving Pen able to perch up front and let her wings trail behind her into the space that would be occupied by another passenger if there was one.
"How's that work?" he asks, wriggling into the still-intact pilot's seat.
He verifies three different ways that no one matching Pen's description has arrived on Barrayar recently through licit channels.
He sends his mother a message.
"I have a... I can't begin to explain, but can you please come by Vorkosigan Surleau at your earliest convenience? Thank you."
Then he goes outside to watch the little girl fly. Hopefully she isn't halfway into the mountains by now or some damn thing.
And that seems a reasonable childhood activity. Of course, what does Miles know? Come on, Mother... he hopes she's not too busy to check her messages. This isn't exactly an emergency and he didn't advertise it as such, but it's not a situation he's going to be comfortable handling by himself indefinitely.
She doesn't go in far enough to get even her wingtips wet. "There a lot of daddies too. Maybe more if counting the soul animals. Shell Bell has one soul animal and the boy one has one too and also the owl one who had owl first of everything. But some daddies also, and! And when a one Daddy gets one, it can turn shapes."
"Well, for Shell Bell is special. But usually, it eat a regular door. Like, door to room, something - poof, now goes Milliways. Go in, go out back where coming from! Jane do time too and she have part in back yard of bar, but, without Jane do time, time only go if door open. So stay longest while come out still whenever. Shell Bell stayed weeks sometimes when she little to find stuff for bring home. Now she have enchantress aura and can make door eat any door she want, and when going out again can go other place. Home or Downside or anyplace. Jarvises can make door in them whenever wanting to also, if practice."
Or not by accident, if someone wanted to strand this little girl on a hostile planet, perhaps for reasons having to do with her powerful parents.
Which will make it hard to track them down, in the not-by-accident case.
Inside, he shows her the holographic console where holo-games may be found. A splash of sparkling colour arcs up above the vid plate and forms the words PLASMA RAIN. Miles starts the game in tutorial mode for her; the computer guides her through arranging the field of play so that a stream of jewel-bright blue-green water can reach its target.
"Mother!" Thank God. "So, supposing your only known point of entry into the multiverse was a mysterious bar named Milliways with a habit of capriciously usurping arbitrary doors, and supposing you had someone in another universe you urgently wanted to talk to, what would you do?"
"...Possible source of instantaneous interstellar person-to-person communication," he says. "In the form of, um. I fully acknowledge how crazy this is going to sound. An eight-year-old girl with functional angel wings, who showed up tracelessly in some nameless street in the capital, where Ivan Vorpatril found her and rescued her from some nasty customers who probably objected to the wings, and claims she got here via the malfunctioning door of a magical multiversal bar called Milliways. Apparently her parents are some kind of interdimensional big shots. I have verified the magical person-to-person communication, though not whether it obeys the speed of light. I can add you to the circuit; it will involve a little girl saying hello in your mind, and then you'll have 'brainphone' access to - well, currently, me and my mother and the interdimensional eight-year-old."
"We want to find out whether the brainphone works well with people who are very far away, so we thought of someone we know who is very far away right now. If it does work well with people who are very far away, then we can use it to talk to people on other planets easily, instead of having to send them a letter and wait a week for them to get it and another week for them to send one back. And that would be very nice."
"Only one more right now, and probably only a few more after that," she says. "Because we aren't sure yet what the best way is to tell people about magic without upsetting them, so we're keeping it a secret for now, until we figure that out. Which might take a long time."
His next mission is to Jackson's Whole, just over a week later, the day after his father and Gregor are added to the brainphone. He asks Illyan to agree to comm-silence-except-in-emergencies despite this amazing new technology, citing the difficulty of maintaining the Admiral Naismith cover with his ImpSec boss pestering him at all hours. Illyan acquiesces with only moderate sarcasm.
The mission is... one of the more harrowing he's had. He makes some enemies. On the other hand, his new recruit is amazing.
On the way back, the very day he parts ways from the fleet, he walks into his tiny cabin on the commercial passenger transport and, when he looks up from rubbing his eyes, discovers that he is not in a tiny cabin on a commercial passenger transport. Not at all.
'We found the bar' is on the list of pre-approved emergencies under which they are allowed to contact him by brainphone, so he knows they haven't. He also knows they were going to ask Pen for better contact information regarding her parents and their alts, when he left; they hadn't yet expanded the search offplanet, so it was not yet urgent to do so. Of course. And now he's found the bar, and - he checks his chrono and does a quick mental calculation - it's the middle of the night on Barrayar. Of course. While he could wake up his father, his mother, his boss, or his emperor - or that poor Byerly fellow he barely knows - and ask them for an update, that would be rather impolite, and also involve holding open a door to Milliways from a public corridor on a commercial passenger transport while he tries them all to see who hasn't put up a [sleeping] busy message.
He stands to one side of the closed door and mutters curses to himself in several languages and dialects.
"I, ah - are you looking for something?" he asks.
It would be a ridiculous coincidence - or maybe it wouldn't; after all, if he remembers right they do have someone who can do just that to doors, and it would be the first thing they'd try the moment they noticed her missing, and if he interpreted the weird time bullshit correctly then the moment they noticed her missing would tend to fall right around the next time someone from his universe encountered the bar.
And appears where Pen is.
Aww, Pen's asleep. Well, Jane can send her home just fine that way, and she can come back to visit if she wants. Poof goes the little angel. Shell Bell leaves a note on the bed - Pen's auntoid came to pick her up, she is home - and then teleports back to the nice person who let her in.
"Thanks."
"We're not actually sure! I mean, we know what happens, but not why. But we - I'm a Bell, so's Pen's mother - cooperate with ourselves really well, so we formed a network to share stuff. We have the same personality and some strange coincidences in circumstance and we look the same. Except for Cam, who is a boy."
"You don't look familiar, but I can call Glass in to check to see if you're a new face of somebody we've met. If you're not, you can leave notes with Bar, or just loiter indefinitely in Milliways, but there's no guarantee this'll get you in touch in a reasonable time frame."
Cath meows declaratively and at some length.
"She says it's not all that difficult to get her point across these days, but she wouldn't recommend it to most people because of the effort involved in getting to that level of understanding."
"I'm generally reluctant to agree that people may do things to my planet's computer network without knowing exactly what they entail, first of all," he says. "And duty obliges me to pass the decision on to interested parties such as the Emperor, who is a good friend of mine, and the head of Imperial Security, who is my boss, rather than make the call myself."
"Of the Cetagandans I've met, she struck me as the most reasonable, practical, and friendly," he says. "I would and have trusted her with my life. But she operates under such a heavy mantle of security at all times that I would expect her first reaction to anyone contacting her unexpectedly through unusual channels would be extreme alarm, and I don't think that's the kind of first impression you'd rather make, even if you clear it up very quickly afterward."
Addressing the Bells present, she adds, "Aelise's situation was a pretty unusual one for the template. I don't think you'll find Lisbet doing things you'd disapprove of unless she's doing them to avert an extinction-level disaster." Back to Miles. "Are there any extinction-level disasters looming in your world?"
"The exciting news thing is a major bottleneck. You can't have anybody you can't explain or convincingly lie about unless you have a credible case for being able to handle the revelation. I did my own world on the sudden sharp shock model but I had a small, low-tech population. But we can add your world - right, Glass?"
"Oh, yeah, bog-standard there," says Glass. "Not too mean, no competing afterlife or anything. Miles, d'you wanna be immortal? The brand of immortal involves looking like you catch fire and then being restored to perfect health under any circumstance that would normally kill you. It'll fuck with your visible aging, though."
"Well," he says. "Reuniting the kingdom by marriage is a pretty obvious idea, but the circumstances have never quite lined up. And then I fell in love with Duke Reko of Ferdinandia. Since the original incident involved an adoption, though, we want to secure as traditional a succession as possible before we try anything."
"It's called a uterine replicator," he says. "There's actually an entire planet populated solely by men who use replicators to gestate all of their children. But in the rest of the galaxy it mostly serves as a safer and more convenient alternative to, um, conventional gestation."
