"Welcome to the House of Arch, Wei Wuxian," he says, breathing deeply with the contentment he always feels when he is once again home.

"The common rooms are accessed through the paintings here, that show a visual representation of where they lead. We've a library and gathering space, a shared courtyard that leads to an outside for sparring and weaponry lessons, and we used to have school rooms when our eldest children were younger. The tutors all came from Milliways."

He points to an innocuous landscape painting. "This one takes guests to their own gallery of personal rooms and suites, and our family gallery has its own painting, as well."

Which he doesn't point out; there are other ways guests can chime the family rooms than through the main gallery. There are other paintings hanging still within their frames throughout the gallery. Some are traps for interlopers who may get this far; some lead to disused rooms. A few only Tom and Door know where they lead.

"I hope coming through wasn't unpleasant. If you'd like a tour, I can give you one. Would you like to visit the library?"

He thinks the answer may be yes! Or at least, he hopes it is.
