Kithabel is sitting on the flat top of the tallest tower of her palace, forcing the rain to decline to fall on her, taking a break insofar as she ever takes a break. She has no constructive ends to pursue right now, so she's playing with the lightning in the clouds overhead. She doesn't want to try taking a direct lightning strike yet - she could probably take it, but only probably - but she can tell it to arc here and there in patterns, she can ball it up and watch it roll through the air, she can make it turn colors. She's making sure none of it hits the town, and if it starts a fire in the woods she'll take care of it, but at the moment it's a toy.
Kithabel sighs. "Fine. ...Look, obviously I can't undertake much interdimensional travel myself without losing things it takes ludicrous amounts of time to get back, but if you're amenable I would not mind being visited for occasional swaps of otherworldly souvenirs for anything you might find useful locally. I won't be up to sorceress quality strength again for several years, but lower-grade momentum can still accomplish things and I'll be where I was again in another decade or so."
"Take one of these," she says, pulling a wooden bead off her bracelet. "I don't know if they still work after having been removed from the world, but if they don't they won't do you any good anyway. Talk to it and I'll hear you, if it works, and vice versa."
"That's clever. I wouldn't have the first idea how to make one of those." He accepts the bead, and squints at it. It continues to look like a bead.
"Testing," echoes the bead in Skeeve's hand.
"Anyway," as he turns slightly red, "I'll see you when—" zap.
The next thing Kithabel hears, first the usual way and then through the bead, is "Not again."
"Where'd you land this time?" she wonders, motioning to Merlin and heading for the lift that will take him off of her waterfall.
"And this was an 'again'? You didn't mention this ever happening before." Merlin is shown the lift and given directions from the bottom of the falls to the town.
On the bright side, some short guy had just dropped something. And I caught it, so, on balance, came out one ring ahead."
"Have fun with that." Merlin having been shooed, Kithabel goes back into her castle, and starts trying to do magic. Again. From the beginning.
