Esteban says, "Where's Arachne? Her spiders could go right through."
Ludwig does as commanded, though he does gesture with a few primary flight feathers extended Carmen's way.
But as a reminder, shapeshifted humans are still subject to Corpus spells in 5th ed. Only a Bjornaer in Heartbeast stops being subject to Corpus effects.
(Since The Fixer is out of commission for the immediate future...) Arachne is outside the tower investigating a mass grave found by her spirit companion. Egon, Vulcanus' familiar, is with her, though he's doing so in human form rather than as a giant warhorse.
Vibria opens her mouth to say something, but Ludwig crosses, grabs the wand, and flies back again before she gets anything out.
She does smile at Ludwig being rude to someone besides her for a change.
((That's what I thought, I just wasn't sure if there was a house rule I had missed and hadn't double-checked yet.))
[color=red]"They should still be affected by an anti-Corpus ward, though, shouldn't they," she says thoughtfully.
[color=red]"Perhaps instead of an anti-Corpus ward, it's more along the lines of an Animal anti-ward?"
She presses against the ward, takes a breath, and puffs a small (2-3 foot) gout of flame. She then kneels, takes the hem of her skirt (which, I think, is wool and ergo Animal), and tries to wave it through the field, pressing her hand against it to see exactly where it is.
The flame extinguishes immediately upon leaving Vibria's lips, and the temperature in the lab drops rapidly. Within moments, it becomes cold enough to drop a Fatigue level to everyone inside the lab.
On a Perception+Awareness of 9+, people will notice that the lab equipment all has a thick layer of frost on it (which was not there before there was an open flame in the laboratory).
[color=red]"Well, so much for that theory," Vibria mutters through chattering teeth as she wraps her arms around herself.
((Per 0 + Awareness 3 + die roll of 6 = 9.))
She steps back from the ward, shivering fiercely, and weighs the risk of casting Robes of Proof Against the Cold (which she can do, even in this Aegis), and decides against it...for now.
[color=red]"I hate the cold," she chatters.
((great...I accidentally triggered the lab's fire suppression system 
))
Exactly 
He's a Verditius! And he experiments a lot!
The chill only lasts for a Diameter, and assuming there is nothing in the lab hotter than body temperature and/or warm mead, the room temperature will return to normal.
The ceiling here is twice again higher than it needs to be, and the ceiling is curved into a dome; stylized-yet-scientifically-accurate paintings of the constellations adorn the dome. A teaching gallery overlooks the lab, with a few catwalks leading out and over some of the lab's features: There is a large stone platform engraved with runes, an astrolabe, two suits of armor, and a large (but currently empty) cage. An ornately carved writing desk sits under a magical lighting fixture, and a shelf of neatly organized texts sits above the desk. Flanking the desk are two large chests, one wooden and the other iron. The lab equipment is of exquisite quality and it's stocked with priceless ingredients, and there's enough equipment in here to make up three standard Hermetic labs. There are two wooden doors on opposite sides of the room, a large open balcony overlooks an idyllic summer scene below, and a spiral staircase seems to vanish directly into the solid domed ceiling.
((mmm...warm mead drools ))
Vibria looks through the ward, hands on either side of her face, gobsmacked by all the incredible...stuff on display there. I mean, really, how much lab equipment does one magus need? Even if he is a Verditius? And especially when there are people in this very room whose labs are just barely adequate for their needs?
[color=red]"How do we get this back to Andorra?" she says, not even bothering to wipe the drool from her chin.
Carmen ficks off Ludwig in return. Pinche pájaro estupido!
(Carmen's native language is Catalan, but she learned how to curse from her Castilian father )
I just checked HoH:MC, and Ryu is right. Just as Vibria had thought (after the hussy took credit for the sg's information 
).
Carmen is brainstorming ideas. How did Ludwig cross through? Is it his faerie nature? Or did he trigger it when crossing? If then, is there a deadly inescapable trap he is now in? Is the stupid bird covered in frost now? :lol
and we know how that worked out 
lol
Shiverring, Carmen frowns at Vibria. You are as subtle as a hussy in a brass bra bull in a pottery shop.. But when she sees Ludwig covered in frost, she chuckles and says You may be on to something though
Carmen then sloly and cautiously tests the limits of the barrier, where exacly it begins and how large a dimension it seems to be blockading. If I am visualizing it correctly, I am thinking the stairs go up to an open doorway at the top of the stairs, which is where the barrier is. We can see inside the lab, but cannot get into it.
And we can see...
The iddylic scene is obviously from within the regio, so trying the balcony from outside won't work. I am thinking the spiral staircase up into the dome is the same as Carmen saw looking into from outside the regio before?
The crow is not covered in frost (only the lab equipment actually has frost on it), but when Carmen looks at him, the bird doesn't seem to be bothered by the cold, either.
Ludwig flips back into a human. "Y tu mama tambien," he grunts (the only words in Spanish that he knows).
He then blinks, and suddenly shivers. "Scheiße! Ist eiskalt!"
Yep, the entirety of the doorway is invisibly blocked in one smooth surface.
Not the same one / not overlapping areas of the real tower and the regio tower. When Carmen flew into the balcony she was on the third floor of the physical tower; the third floor of the regio tower is the level with the studio and antechamber, and the lab is on what would be the 4th floor (assuming that there are the same number of floors in and out of the regio).
But in theory, a variant of this room might exist on the mundane level, right? And the ward would not exist on that level?
Ludwig! Do you have Second Sight?
"It don't take faerie eyes to know you need to change your panties whenever you see any man with a pulse," Ludwig snarks back in German. He turns to Bernhard: "I point out how stupid you all look when you're all prancing around invisible, and "do you have the Sight" the silly bint asks. I thought magi were supposed to be smart."
While Carmen doesn't know German, it was very noticeable that at one point Ludwig's voice rises two octaves for a bit, sounding obnoxiously rude but also uncannily similar to Carmen's own voice
He turns back to Carmen. "I am see as goblins see. Look at things humans not look," he replies in broken Latin. (On a Perception + Folk Ken of 9+ anyone would notice that while Ludwig's Latin is broken, he doesn't pause to think of words the way someone genuinely unfamiliar with a language does... it would become obvious that he's only faking being bad at Latin.)
Carmen rolls her eyes 
What I am getting at is asking you to try and see this room from another perspective. The mundane view. If this room exists on the mundane layer of reality, and you can percieve it, you should be able to cross unhindered by the barrier that exists on this layer. If so, then perhaps you can see back into the regio and find us in the hallway. Then we enter the room on the mundane layer, and you can lead us into the regio from within.
Do you comprehend any of what I am saying to you? Or do you have the wits of a bat-bird?
Vibria watches the exchange between Carmen and Ludwig (and Bernhard) with a barely-concealed amused smile, feeling a sense of schadenfreude at their sniping at each other.
((Per 0 + Folk Ken 0 + die roll of 3 = 3. Yep...clueless. Just as I thought.))
Ludwig makes a vulgar gesture at Carmen with his left hand and his tongue. "Ain't no overlap, stupid bint," he leers. "Second level, boundary downstairs. Lab not exist mundane view. You would know if not blind bubblehead bint." He wanders off into the lab and starts fussing with the iron chest. (Per+Awareness 9+ to see that when he touched the chest, a phantasmal chessboard appeared, and Ludwig is moving pieces around. 12+ to notice Ludwig doesn't know how to play chess. 15+ to notice the board keeps resetting to a starting board whenever he makes an illegal/nonsensical move.)
(thinking...)
Wait. What's that over there?
Pinche cabron! The giant cage? on its floor lies a very familiar looking, soiled, moth-eaten, threadbare, carpet.
Who's calling who a male-goat here?
That was supposed to be your internal monologue 
Caduceus is the cabron, obviously!
(( dost thou truly speak of The ever-lovin' Flying Carpet? It's not gonna change her mind about wanting a new one ))
