OK, to summarize:
- Carmen and Estaban are going up to the door. Oscar and Armando will be trailing them to the door (magi travelling without an escort would be odd), but will wait outside politely.
- Stealth Team: Vibria and Bernhard will be under the Cloak of Invisibility, Arachne can turn herself invisible.
Ludwig looks straight at the invisible Arachne and snerks, "That trick, for you usually work?" in broken Latin, before turning to the two under the invisibility cloak. He stares right at them as though the cloak isn't there, and says to Bernhard in German, "Hey lunkhead, take off your shoes." He scowls at Vibria and Arachne, and points at the womens' feet. "Boots noisy, feets quiet" he grunts in Latin.
The face team knocks. A few minutes later, both the double doors open simultaneously, being opened by servants, while a smartly-dressed butler stands in the center of the foyer, hands clasped behind him and wearing a professional demeanor. He doesn't ask questions and doesn't even look very closely at the two magi before inviting them in. "Apologies for the wait. We were not expecting any customers." The stealth team has no problem sneaking in through the doors as soon as they open.
"Your men may wait here," the butler says, opening a door underneath the stairs, into a formal sitting room opening just off the grand foyer.
"The master's business is conducted this way," he intones, and then leads Carmen and Esteban up the foyer's grand curving stairs, to a landing on the second floor, where a central staircase leads up to the third floor. As they go up the second flight of stairs to the third floor, Carmen notices immediately that these stairs, while in the same physical place as the ones she looked down at earlier, have not a speck of dust on them.
The stairs lead into a sitting room with a familiar-looking balcony... but the scenery outside is lush and verdant, in full summer bloom, quite unlike the early spring outside the tower. "You may wait here. The mistress will be with you shortly." The butler bows and disappears back down the stairs.
This sitting room is clearly a sanctum antechamber; there are three doors (all of which are closed) and one of them has a prominently-displayed sanctum marker.
If Arachne, Vibria and Bernhard wish to trail the other two closely, I will need Dex+Stealth rolls, otherwise let me know if you want to wait and follow along at a conservative distance.
