Five witches besides Isabella ward the colony site. Robots guard the site of the portal, obligingly letting colonists through during scheduled trips and reporting to Isabella by mirror if anybody else shows up. Other robots help the colonists with setting up their farms and houses in the warded area. It'll hold a city, no problem, although another transfer of silks and bags to pay for warding a second site is going to be called for before they get literally everyone across, since in addition to city they need farmland, and since they can't build vertically as effectively as fully industrialized Earthlings or the deceased aliens.
One day:
"It's been exactly a year now since you crashed my picnic. Let's go to a fancy restaurant and celebrate."
"Okay. Mirror me if you need something, try to avoid the hotel people needing to call me, I'll let you know when I have a place for you to park in my hub building, and you," she waves at Xiara, "can teleport away to a nice remote location whenever you have the mana - do make sure it's remote and not secretly on a cruise line or a nature trail or an oil tycoon's hit list, mirror me to check if you're not sure."
"Very well," says Xiara. "I feel as if I should have you check regardless, since I do not know what any of those are."
"And how much of an architectural footprint are you going to leave if seen from the air?"
Isabella turns to leave them.
There is Adarin, cross-legged by the door, conversing quietly with Vernaia. About - stuff. Apparently.
"So I am a little annoyed that they interrupted our anniversary," says Adarin. "Something with mages and timing."
"They're really not very good at it, are they. Well, it's not midnight yet. Still time to do any other anniversary things you had in mind."
"Well, I will be amenable to anything on the menu when you've made a selection, my dear."
He puts Vern down, then - kiss!
Vern trills up to Path. Cuddles? Cuddles and daemon talks?
While their humans are busy, Vern asks Path, "Want to know about what Adarin and I were talking about?" (Nuzzle.)
Vern giggles, nuzzling Path. "I figured. We were talking about if we wanted to marry you. We've decided that the answer is yes, but Adarin will want to - get everything in order before he actually proposes."
"Everything everything meaning planning out the wedding, too? No, he'd want Isabella involved in that, but... Finding a ring, making sure her father will not make angry faces at him over the dinner table for wanting to marry her, that sort of thing."
