"Where do you think I should put the underground secret father house?"
"Mmm, there?" suggests Cam. "Not far from the tree but not so close that if people are making noise when we come through we'll wake him?"
And then, without further ado, she starts making her dad a house. An underground one, created by turning part of the ground to air and then transmuting supports to keep the entire thing from collapsing. She's borrowing the floorplan she used when making her own house in Heaven - it's pretty suited for a bachelor, though she has to add a kitchen that was basically absent before.
"Think you can add a generator so he gets power? I don't know how to handle plumbing, either," she admits to Cam. "I can do the pipes no problem, but I don't know how to manage infinite water."
"I don't actually have proper plumbing in my house, I just make water as needed," he muses. "I'll copy your station's circulator, and yeah, I can do a generator no problem." In he goes to accomplish that.
Adana starts adding finishing touches, turning the walls to a nice color, changing the floor to carpeting and a hardwood flooring in the dining room and kitchen. She's going to leave the technological things to Cam, but she can do the wiring herself. Electrical outlets (shaped differently than Max, Ice, and Cypress are used to) are put on the walls, along with light switches (but no light yet) and plumbing.
"Well, that didn't take very long," says Adana, brightly. "But I don't think your portal hub will be as easy?"
"We'll want to sit down and draw up plans, and maybe wait a bit to let Katydid and Rain and Phix weigh in too for a more comprehensive survey of relevant aesthetics," says Ice.
"Just as a recommendation, knowing my sister and her alts - at least one room for liaisons. Soundproofed. Also easy to clean blood off of."
"If they don't, I will invite them to a delightful party where they might make the acquaintance of Lord Bucket of Soapy Water and Lady Mop. Because I'm not doing it."
"Ick. I may have magic powers that makes me good at cleaning things, but - no. Just - no. I would have to personally turn everything there to air or something, and - no."
"Offhand I can't think of any materials to make the walls out of that will completely obviate the need for someone to occasionally clean it. Little wall-climbing scrubber robot, if the Zevs don't handle it?" he suggests.
"... Trial period, to see if they will clean up after themselves. And if that doesn't work, wall-climbing scrubber robot."
"Messy. Teleporting the contents of the room into space would be better."
"It does, doesn't it. And time is actually an issue now, I'd forgotten. Hm. I suppose we could pay other people to do it, but that seems unnecessarily cruel..."
"I can make a little scrubber robot, guys, it'll take like a minute."
"They're joking, sweetie," giggles Adana. "They were not, at any point in time, planning to burn the place to cinders or teleport its contents into space."
"Okay. Anything else we should do here before we go make ourselves a - what are we, Bells - a Belfry?"
