While Sable practices walls, Neo sketches out a design for the tower and what goes where. A bit of math about dorms and common rooms and the minimum wall thickness for the magical reinforcement spell (half a meter) gets her a tower diameter of twenty and a half meters, including a central spiral staircase. The ground floor gets to be entirely taken up by the infirmary. An animal processing shed goes in a wooden outbuilding against the outer wall. Next floor up is seven training rooms, one per element, with a study area in the center full of desks and tables. Then seven apprenticing rooms, again one per element. These two are the closest rooms to the infirmary because they're the most likely in-tower buildings to produce injuries, so they should have the shortest trip. That's also why the infirmary is on the ground floor, to allow injured hunters or defenders from outside the tower to be brought in quickly. The next floor above the training floors is the kitchen and dining room, with lots of round wooden tables and comfy chairs. 

Then above that go five floors of dorms, just to future-proof. Every dorm floor has twelve dorm rooms and two bathrooms, evenly divided radially, each room four meters long. Each dorm gets a bed, a window, curtains, a wardrobe, a desk, a chair, and some bookshelves over the desk. The central area of each dorm floor has a common lounge, full of comfy couches and chairs, tables, and more bookshelves. All the bookshelves get filled with blank notebooks to start, and stacks of looseleaf, binders, and pens and pencils. They've handled enough of all of those to conjure them freely. Above that goes a crafting floor, then a research office and lab rooms. The crafting floor only has the wand shaper for now, the research office gets the research desk the previous Magisters talked about, and the labs have tables and open spaces and bookshelves of notebooks and such.

Finally, the top two floors are special. The second-highest floor is the Headmistress's suite, reserved just for the five of them, and optionally anyone else who joins their little polycule. There's a very small landing area where the stairs reach the floor, but otherwise it's completely walled off. It features a cozy lounge, a private office and workshop, a deeply luxurious bathroom with an enormous bathtub, two smaller bedrooms in case someone needs their own space, and a fucking huge master bedroom. The bed there is wider than an Alaskan King, wide enough to make this bedroom the largest room on the floor, because the five of them refuse to ever sleep alone again. They have each other to cuddle now.

The highest floor is the auditorium, because there doesn't need to be a staircase obstructing the center of the room. The center is then reserved for the central stage (with just a little hatch to enter through), and gradually raised seating radiates outward from that.

Sable gets the practice walls the way she wants them, a mix of swoopy and spooky, dark grey stone with lighter accents. She knocks all of that down, readies Neo's design in her view in mindspace, and starts shaping it into place. Most rooms get cherry or mahogany for their furniture, though for the dorms she does a variety, alternating through a series of cherry, mahogany, cedar, redwood, purpleheart, and ebony for each dorm. She lays plumbing through the walls to the kitchen and bathrooms, connecting the waste flow to a tank below the processing shed for the midden jellies. 

It takes time. There are a lot of rooms and beds and furniture to fill the rooms with. But they've handled a lot of furniture and materials in their lives, so between the other Pirates conjuring materials and books, and her slowly shaping everything into place higher and higher, they can get the tower built.

Learning stones go into the training rooms. Potted plants go into Nature rooms. Arcing electric widgets go in the Lightning rooms. And so on.

Anything that requires an unavailable magical material gets a placeholder sign instead.

But eventually it's finished. Eventually they have a tower that they can run an academy out of, that they can teach themselves magic in, that they can call home in this strange, apocalyptic world.

She collapses into an armchair in their suite, sighing tiredly.

The smokeless torches from page 98 turn out to just take a few Phoenix's Kiss petals each to make, plus wood or stone or metal to shape into the sconce, and provide adequate if dim lighting to any room not reached by a window; they come out looking just like the ones downstairs in the book room and so on.

All in all, constructing the tower takes the rest of the day and well into the night. An unfamiliar moon shines brightly through the windows, making the Ice Flowers growing outside sparkle brilliantly against the damp, dim grass. A flightless bird the size of an entire human toddler waddles out of the fog and starts pecking at a gutberry bush, its dark purple feathers sticking out every which way to form a spiky silhouette.

Maya steps close and scoops Sable into a princess carry "My lovely Captain, our lovely Headmistress, you tired yourself out building us this lovely home. Let us go to bed, beloved."

She leads the way to the bedroom, Sable in her arms, and everyone switches to sleepwear along the way with a bit of coordinated looking away from each other. Maya switches to a lacy bra and panties set in silvery silk.

Ruby switches into a cute little black spaghetti-strap camisole and soft red shorts, blushing slightly.

Hailey winds up in just a black bra and panties, fairly simple, no lace.

Neo goes for something pink and lacy

And Sable, with a bit of a blush at being scooped like that, winds up shifting down to a petite, white-haired form, with red eyes and lacy violet lingerie.

The girls all pile into bed cozily atop each other, intertwined and snuggled close, with Sable firmly in the middle.

And they drift off to sleep.

When they all wake up, Sable's feeling cheerful. She's also a redhead with fangs. She kisses everyone good morning.

Then she rolls atop Maya and deepens the kiss. 

Hailey tugs Ruby in between her and Neo.

And a very good morning is had by all.

(Normally this would be shown in detail, but selves-threading is hard.)

Ruby (with a giddy smile and a blush on her face) heads off to the various crafting and processing areas to make a list of what didn't get built 'cause they were missing some material or another.

Neo curls up in an armchair and sketches designs for the gardens and other things they might need on the grounds.

Hailey and Maya look through the book for anything they need to do that hasn't been done yet.

And Sable heads down to the Mana Font to see about expanding their safe range by repelling more fog.

It's a quiet morning, though it seems the fog has made a few feet of progress creeping up on the tower overnight.

Ruby might notice that something odd has happened to the potted plants in the Wand Shaper's crafting room (and, if she checks, also the Nature focus room). Everything looked normal when the Pirates went to bed, but now all the fruits, flowers, and herbs are looking distinctly different, some more obviously than others.

The jade plant's thick green leaves seem to be made of literal jade; the round pods of the string-of-pearls have taken on a rocky hardness and pearlescent sheen, though they're still vibrantly green. The aloe's spiky leaves are ten feet long, threatening to tip over its tiny pot. Most of the fruit on the fruit trees is bigger and more brightly coloured; the plums are a purple so dark it's nearly black, and smell absolutely delicious. The mint is sending runners out of its pot in search of foreign soil, and has nearly strangled the rosemary with them. The roses, dahlias, orchids, tulips, and lilies have all perked up into massive blooms; the ones with brighter colours are crisp and vivid, whereas the paler flowers are ethereally delicate and beautiful. The blackberries are dripping some kind of inky liquid on the floor.

The potted plants are doing what?

Cool!! And they're so pretty! And they smell good!

She'll try a plum.

Wait no mint you're not allowed to attack your neighbors! She clips the runners and keeps the mint back in its own pot. If it tries again she'll have to sequester it somehow. Maybe a glass case or something.

And what's the inky stuff dripping from the blackberries? Okay, she'll collect that in a sample vial. Actually, she should really be collecting samples of everything. Sample jars, bags, and vials for all of you, planties!

The plum's blood-red flesh is sweet, juicy, and strongly flavoured, like some kind of plum concentrate - but the taste is fresh and bright, with vivacious subtlety, not cooked-down and smoothed-out and condensed into a homogenous syrup.

The jade leaves and pearl pods appear to be real rock, smoothly integrated with the living plants - right down to having veins of living plant matter threaded through them.

The inky stuff is dark, opaque, sweet-smelling, and eager to stain whatever it touches.

The mint seems content to give up its runners, for now. Time will tell whether it stays tamed.

All the herbs smell stronger than they used to, and most have bigger or more vivid leaves; the parsley is crinkling like a profusion of petticoats. Nobody except the blackberries is actively dripping, but the strawberries are juicy enough to smear her fingers with red just from the faint pressure of being picked.

Wow that's kind of awesome? They'll need to figure out if these things have developed any kinda magical properties, because they sure seem to be magically enhanced. She puts all the samples onto shelves in the research lab.

And after a bit over half an hour, Sable tromps back up from the Mana Font having pushed the fog back again. How much space are they up to? Any new plants revealed?
