"Now," says the witch, "you are absolutely welcome to keep the set of legs indefinitely. However, my personal skills run more towards the encapsulation and the transference, not so much to the sticking. They have ludicrous numbers of practical magicians on land, I'm sure you won't have any trouble getting someone to attach them permanently if you like them. If you can't, they'll come off and you'll have a tail again, but I can reattach them for another try, no extra charge." She plucks the glass containing the legs off its coral shelf. "Do we have a deal, my dear?"
The transfer takes about five minutes of humming concentration, and the moving shape in the glass changes, and Ariel's tail is sliced right through the middle and changed.
She makes a face, then shrugs.
Swimming with feet is hard - she misses her flukes already - but she gets the hang of it after a few false starts, and she leaves the witch's reef, and she heads for the surface.
The beach where Zoyah's brother washed up isn't too far from the palace. Zoyah is poking around idly, looking for any signs of a speaking seal or a dolphin with hands or (Kerem's outlandish notion) a mermaid. So far she hasn't found much.
A woman with green hair and bluish-greenish skin pops her head up out of the water and climbs awkwardly onto the shore.
"Uh, hi," she says, "do you want to borrow my overskirt?" She poises her hands over the buttons.
"I think you had better borrow my overskirt," says Zoyah. She unbuttons it - she's got three layers on under it; it's a chilly day. "Here. What happened to you? Did you almost drown like Cymbeline? He washed up here the other day, saw funny tracks in the sand, but I don't see anything weirder than you around. Speaking of which, where did you get those colors transferred from? Who did the magic on them? They're a good look on you."
Then she makes a face, and takes a deep breath, and water flushes out of long green streaks along her ribs. She bundles the skirt into one hand and uses the other to brush sand away from her gills.
"Youuuu have gills," observes Zoyah. "...Um, the skirt, you wear, it, you step into it and then button it up."
She fiddles with the skirt a little, manages to get one foot into it, manages the other, pulls it up around her knees. It is upside-down and covered in damp sand. She is still sitting down.
"Other way around," says Zoyah of the skirt, gesturing, "And you have to stand up, to get it on right, and you've got sand all over it, don't they have skirts where you're from?"
"Do you even speak Loegrian?" asks Zoyah. "Um, wave your hand if you understand me?"
With the buttons undone, it neglects to cover the crucial area. The stranger does not appear to notice this deficiency. She's wearing a halter top of some kind of grey leather, so she does know how clothes work, but lower-body coverings don't seem to be her area of expertise.
"Parlis Aquitaniais?" tries Zoyah. "Latinitas?" (She is a well-educated princess.)
