The front doors of the Scarlet Devil Mansion swung outward and Yuyuko drifted slowly inside, settling on her feet as the doors shut with an echoing boom. She looked around the empty entry hall, but the only light sources were carried by the wispy phantoms that attended her, so she couldn't see much, even after advancing into the middle of the room. The gatekeeper had been most courteous, and had even let her enter without an invitation after she had explained the reason for her visit, although she had been told to stay in the entry hall.. "… But this is odd. Mysterious and spooky, even! Maybe I should go exploring to find out what is wrong?"
"Nothing is wrong, Lady Yuyuko." The words were accompanied by an immediate increase in the level of light, and Yuyuko turned around to see the chief maid of the mansion standing behind her, iron lantern in hand. She put her hands over her heart in mock distress.
"Oh! What a shock! You nearly killed me!" She grinned at Sakuya, but the white-haired maid simply bowed her head and walked past her.
"If you will follow me, Milady will see you in her office." Yuyuko frowned but followed the maid, humming to herself in an effort to improve the mood. Her phantoms were cheery sorts, and the strangely gloomy atmosphere of the mansion was putting them out of sorts.
"… Are you sure nothing is wrong? The mansion isn't usually like this." She studied the halls as they walked, trying to keep track of where they had gone, but something felt wrong about that. Was the bleak ambience affecting her, too, or was something more sinister afoot?
"Nothing is wrong, and this is how the mansion normally is. If we aren't expecting visitors, unused areas of the mansion are kept dark. If someone does have business to conduct in those areas, they are lighted appropriately." Yuyuko looked meaningfully at the unlit sconces set into the walls and sighed to herself. It was not an entirely unexpected reaction to her presence - she had told the gatekeeper she was here for business relating to Yukari, after all - but it was … disheartening, considering her friend's worries. She thought about the vampire she was going to meet and considered again her surroundings. Remilia didn't seem like the sort of person to deliberately cultivate such a dreary atmosphere; menacing, yes, and hostile, of course. But this … almost depressive feeling? She shook her head. Had something come through the portals that was a threat to Gensokyo? That was hardly something she could ask Sakuya, of course, so she simply followed the maid in silence. After several minutes they stopped in front of a door as unassuming as the rest, and Sakuya gently knocked twice. "Milady? Lady Yuyuko is here to see you." The door opened, swinging out into the hall.
"Come in, Yuyuko. Sakuya, back to your work." Remilia's voice was flat and disinterested; Sakuya bowed and vanished, and Yuyuko stepped into the better-lit office. The door swung closed behind her. Remilia stood beside the desk, waiting for her guest to approach. Yuyuko walked across the spotless room and sat down in the waiting chair. Remilia gave a perfunctory bow and poured the two cups of tea before sitting down. Yuyuko took a sip of the tea - harsh and strong, not the green tea she was fond of. "You're here on Yukari's business again?"
"In a way, yes. I don't think she wanted me to come here, but I think it's important that this be cleared up before your next big party." Remilia nodded and waited for her to continue. Yuyuko pursed her lips for a moment; in some ways, talking with someone who could see the future was worse than talking to a mind-reader. She shook her head - there was no sense in playing around or irritating Remilia by obfuscating things and being coy. "… Yukari has … concerns … about these portals of yours. And your plans for them. In particular, the lack of oversight you operate under." She paused, waiting for Remilia's response. The vampire stared at her for a long moment before slowly reaching for her teacup and taking a long sip.
"You mean to say," she began after setting the cup back down, "that Yukari is getting scared because I'm doing something she can't twist to her own ends." Yuyuko fought back a wince, not sure whether Remilia's lack of visible emotion was a good thing or a bad thing. Or whether Remilia's summation matching her own thoughts was good or bad.
"Something like that," she said, and for the first time since entering the mansion, she saw someone display an emotion. She knew some youkai believed that Remilia was little better than an extremely powerful fairy, fickle and childish, and that Patchouli was the real mind behind the mansion's activities, but they were too foolish. Remilia had been a power long before she had taken the magician into her service.
"'Excuse me, I'm here on behalf of my friend, who is the shadow ruler of this realm. Are you planning to supplant her or foment rebellion against her?' Is that about right?" Yuyuko winced; rather than amusement or anger, what she heard in Remilia's voice was bitterness. "Always, always it's about her and Gensokyo. All the time. … What a waste." She sighed and shook her head. Yuyuko frowned.
"You know how important Gensokyo is …." She trailed off as Remilia waved dismissively with wing and claw.
"Gensokyo isn't the only sealed world. I doubt it's even the most prosperous. It probably is the safest, I'll grant. But it's hardly necessary. It's even possible for some creatures to survive in the outside world without the benefit of a sealed realm. … You should know this already. But, since you've come all this way to disrupt my work, I might as well bark on command like my master wants." She pushed her chair over as she rose and walked to a small cabinet. Yuyuko frowned as Remilia opened a drawer and began sifting through papers, eventually returning to the desk with two of them. Yuyuko read the first one, eyes widening.
"… A contract to not reveal anything I've seen to anyone except an agreed-upon individual. And one for Yukari, too." Remilia nodded.
"Yes. With the qualification that you can share the information if you truly believe it is absolutely necessary for Gensokyo's survival, so long as you require similar contracts preventing rapid spread of the information. And, of course, once the information is widely known, the contract will be null and void." Yuyuko studied the contract intently, but it was remarkably straightforward; no loopholes for her to abuse, but neither were there any traps.
"… So I simply write Yukari's name here, right? And then sign it?" Remilia nodded and Yukari picked up the pen, dipped it in the inkwell that was provided to her, and wrote the names. As usual, nothing felt different … but then, she wasn't trying to do anything against the contract right now. Remilia stood abruptly and walked to the door. "Eh? Aren't you going to keep this?"
"You can keep it if you like. Or burn it, or whatever. Once signed, it's in effect, so keeping the original is only really necessary if you want to keep the specifics of the agreement handy. Anyway, come along, come along." Remilia waved for her to hurry up, so after a moment's though she picked up both contracts and carried them with her. She frowned at the doorway - no longer did it show the dark hallway she had entered from, but a balcony overlooking the mansion's library. A small hand pushed against her back and she walked through; Remilia shut the door and walked in front of her. "Ask Yukari how handy it is to just be able to walk through a door and end up across the house, especially in a mansion as big as this. Besides, it's not like I've had much to do over the decades." They stared out at the rows of bookshelves, stretching farther than Yuyuko's eyes could see, and then Remilia shook her head and walked down a small stairway to the ground floor.
"Yukari said she couldn't look into the area you were using for your experiments …." The vampire nodded and turned so she was walking backward, her expression upgraded to 'neutral'.
"Indeed, I'd hoped we managed to make it right. Good to know that that worked." She grinned at the confusion on Yuyuko's face. "Now, is that real confusion, or do you just want confirmation on a theory you have? Hehe, well, I guess it doesn't matter." She spun back around. "You see, the best defense is someone not knowing it's there, so there are a heap of spells trying to keep that from happening, but we've also put a lot of effort into making sure that no one can get through - not without doing a very convincing imitation of Marisa, anyway. Not that a single Master Spark would break through the wards we set up, either."
"So what you're doing is dangerous." Remilia's barking laughter echoed off the shelves.
"So is Marisa's Hakkero. For that matter, so is a depressed human villager with a grudge and an axe." She glanced at Yuyuko. "Seriously, get Yukari started on making Reimu a grandmother already. If this project of hers isn't going to be done in the next decade, having as many back-ups as possible is just good sense. I've tried telling her that, but maybe she'll listen to you." Yuyuko winced at the vehemence of the vampire's argument, and decided against telling her that Yukari was considering Sanae as a temporary replacement, if anything should happen to Reimu. "Anyway. There are a number of defenses around the project area. First, if you aren't keyed to the area, you simply can't access it because space warps you past it. If you somehow manage to unravel the space-distortion, you have to get past a solid curtain of iron - and there's another distortion on the other side. We don't want someone accidentally getting in, so the only way that could happen is if someone has a natural, passive ability to undo space distortions and let them pass through solid objects. This person would also have to have the ability to do that without setting off alarms from the wards simply tracking people's passage, and then they would have to accidentally on-purpose activate the portals, because we don't simply leave them active. Except that fucking magician …." Yuyuko glanced at the vampire, confused at the muttered imprecation, but Remilia simply shook her head and reached back to grab Yuyuko's arm. Thus connected, they took two more steps. Suddenly, the circular area they were in changed - they were surrounded by desks heaped with papers and books, and freestanding doorways without doors. "Tchah! Patchy! I thought you were going to clean this place up." The magician sat at the lone clear desk, writing or drawing something.
"I've had an attack of indecision. I don't know what aesthetic I should go for." Remilia snorted and shook her head. "So this means I won the bet, right? You'll make me whatever I want?"
"Unless you want to give me a spanking instead. And no Yogurt Pomme Pomme or Ultimate Hamburger. Those just lead to trouble." Patchouli chuckled.
"Will you make me a Ruby Pie? While wearing a cute maid's uniform?" Yuyuko smiled patiently; people put up with her apparent cluelessness, so she could put up with this good-natured joking.
"… Well, what do you plan on doing with these … portals?" Remilia narrowed her eyes and stared at Yuyuko for a moment, then shrugged.
"Well, originally and entirely, they were for Flandre. You might be aware that her reputation is not particularly high; she's considered a lunatic and a monster even among youkai. So she can't really come outside and play, especially since most of the ways she likes to play are rejected by Gensokyoans, and most people can't play with her very well. So, these portals! We find a world where she can play to her heart's content, where it doesn't matter what people think because we don't have to worry about what they think. If Flandre wants to obliterate a city, it doesn't matter. If she wants to try and make human friends, she's welcome to do so - and if they betray her trust, killing them won't matter, because they aren't Gensokyoans." Yuyuko frowned, piecing together what she knew of what had happened so far - what Yukari had told her.
"But … you're planning on telling people about the portals soon, aren't you?" Remilia nodded.
"Yes. In large part because Flandre's choices have presented a need - not only the two Illyasviels, but also the two Tohsakas, and the Mid-Childans as well. But also, because announcing these portals is an opportunity." Yuyuko's frown deepened.
"So you are planning on having it out with Yukari." Remilia blinked, then laughed.
"Oh, please. If I decide to kill her, she won't have any warning. No, this is an opportunity for youkai. You've noticed it, haven't you? They're bored; their powers are waning. The Spell Card system keeps them alive, but doesn't nourish them. And I have access to worlds where they can thrive, flourish. Maybe even grow. And maybe there are some youkai who … just don't fit in Gensokyo, despite its inclusiveness. Of course, there would be … restrictions. I can't very well let all of Gensokyo leave at once - and certainly, I don't want them dirtying my mansion! So what will happen is that I'll explain things to the leaders of the different communities - the oni, and celestials, and tengu, and so on - so they can make informed decisions on whether their kind should be involved. And then they can work things out with Yukari so that this doesn't become some kind of false Incident, or otherwise imbalance Gensokyo."
"And so no one tries to bring home pet reality warpers that will cause an incident," Patchouli said, and Remilia shivered. Yuyuko cocked her head curiously.
"No fairies. Never, ever, at any point, will any fairies enter this space, or a use a portal. I'm not dealing with the headaches their shenanigans cause." Yuyuko nodded sagely; whatever Remilia was referring to, she probably didn't want to know.
"I see. Then … another question. How difficult is - all this? Constructing these 'portals' and moving between worlds?" Remilia tilted her head and looked up at the ceiling.
"It's time-consuming to initially set them up, although I've gotten better at it. If things are properly set up, it should only take me a few hours to find a compatible world. Then Patchouli helps set an anchor, because she's better at magic, and we want it as inconspicuous as possible, so it's actually offset from the true entry point. Keeps us safe from the locals' attention. But in terms of power …." She frowned and cocked her head at Patchouli. The magician shrugged.
"It depends. Anchored worlds are easy to get to and only consume a single tome. Finding a new world depends on how 'close' it is, and how stable the connection is. I think the most difficult world we've found required a human magician's lifetime worth of magic to find and anchor." Remilia nodded, and Yuyuko frowned at the pair's nonchalant agreement, but cleared her face and smiled when the vampire turned back to her.
"I see. … Well, Yukari can't see into here, so I should probably go and make sure she doesn't worry any more." Remilia grinned toothily.
"Of course, of course; I'll make sure to put some thought into any other objections that might be made and have them ready come the party's time." Yuyuko nodded again, and was relieved when stepping away from the sequestered pair brought her out into the library proper, unable to see the now-disquieting portals.
"… I'll just … find my own way out, thank you."
