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."
"...Well, that would work great if at least some fraction of mages didn't know me to be immortal, wouldn't it?"
"... You should not advertise that. Not right now, not when the relationship is comparatively new and they need to settle into accepting that killing you is not the best solution. Who did you tell?"
"That'd be the Liandrils. Okay, they probably told their family and some cousins, but I don't think they would mention it to everyone. I certainly didn't know. They'd want to keep some cards in reserve and waste their rival's chances for action by not giving them all the facts. They'd try the wait you out approach and waste their time. I mean, it's going to get out eventually no matter what you do, but the longer you two are together and obviously not breaking up the better off you will be."
(Isabella demonstrates the use of the faucet in the bathroom while she speaks.)
"Um," says Adarin, finding his voice again in this incredibly awkward topic. "On - which part?"
"Is she talking nonsense, is there some mitigating factor she doesn't know about - sweetie, we do not have to get married if you don't want even if it would in fact send ideal signals to horrible people, I'm just curious if it would in fact do that."
He fidgets, a little. "I never said that I didn't want to get married, though."
"Well, we don't have to get married soon even if we do want to," shrugs Isabella. "Please tell me how to make this less awkward for you, I was trying 'deliberate casualness' but it does not appear to have helped."
"... Um. I will go be - not here, while you talk," says Seraphina, nervously - and then she flees.
(Xiara has already lost interest in the conversation and is messing with the bedside lamp while absently talking to ghosts.)
"Um. Well, do you want to get married? I'd thought it wasn't very important to witches?"
Kiss?
"Well. I kind of - don't like the idea of marrying you for the sake of idiotic mage politics, it's like giving them a - weird place in our relationship, and I am kind of protective of it. But I'm not against the idea of marrying you itself."
He laughs, a little, hugging her. "If I knew that one I would have presented it with a victorious flourish. As it is - I'm not sure. On one hand, getting married right now might help with your personal safety. On the other - it would probably bother me to get married because of them and not because of us."
"It's not like it's hard to figure out that witches are immortal, so I'm not actually sure how the balance on my personal safety works out."
"True," he agrees. "Then I suppose we can just - focus on if we want to, or not. And just not let the bastards factor into our relationship any more than necessary."
Isabella finds the lightswitches for all the room's light sources, demonstrates their use for the mage women, and explains how to order off the menu if they don't want to wander off and try restaurants. She hands each one a key card and gives Seraphina a mirror from one of the spare sets, the other end of which is in her portal bag.
"Thank you," says Seraphina. "Um. How will we pay for restaurants? Will they just - know to charge you, like the hotel did, or...?"
Adarin, meanwhile - retrieves his bird, apologetically extracting her from Path if it's required, and then starts quietly talking to her. About things.
