Better not linger in her starting place too much longer. Yellow's faster than her and may have already come home to a wreck. Thorn might have a habit of checking up on the place, even, just in case. She's invisible, inaudible, unsmellable - that won't help if he sends someone thorough. Or comes in person.
She sets out.
She's been flying for about thirty minutes after her shopping trip when she falls through a tear and squeaks inaudibly and lands in the middle of -
The teeny fairy does not require further help from Eidolon in doing her best to secure this court under her own rule. She issues principally placeholder orders and lets most of the fairies go back about their business, but keeps Peak and Favorite on hand and does a lot of excited zooming around through the air, complete with backflips and squealing, "I got a court I got a whole court it's mine".
Eventually she calms down and goes to have a chat with Eidolon. "Answer everything I ask you honestly and quietly and helpfully and right away and don't leave stuff out. Where'd you learn all that sorcery?"
"I don't know any sorcery. On my world some people have what we call parahuman powers. Mine lets me have any three ordinary powers, whatever I need at the time."
"An ability most people don't have. One person can fire lasers, another is invulnerable and can fly, someone else could build completely impossible machines. Most powers help people fight, one way or another, but a lot do have other uses."
And then he finds that he can't use the power. Orders.
The tiny fairy has now seen him swap his powers around. It probably didn't look like much of anything.
"Partly, yes. I dropped three abilities and replaced one. Most powers are undetectable when not being used."
"It's less boring when I use them. Do you want to see what one looks like? The power I've got right now can do fireworks."
While Cozy is busy taking him for a conjurer of cheap tricks, Eidolon uses it for its other purpose. He writes his message to Promise at her tree in letters of fire and doesn't erase them.
Then they have a war.
Promise acquires 57 darted Fallen as new Kept. Anybody going to try to stop her from taking them home with her?
(The Fallen's doomsday device probably wouldn't have worked anyway. But this way Texas stays definitely on the map. The Chief Director, at least, does not regret having accepted Promise's help.)
...What is this decor. In her tree. What.
She goes back, bumps all the interviews to the next day, and consults Tinkers about a mass juice delivery system. A subtle mass juice delivery system. That they can have done fast.
Very few Tinkers work with living things. Bonesaw says she could make a mosquito deliver juice and leave a scent behind to avoid reaching the same person twice, but one surgery per mosquito would be slow even for her. But she can recommend someone.
Promise goes and asks Plague and Pestilence if they want to help her with juice-delivering mosquitoes.
Bonesaw constructs one with the tiniest surgical implements anyone ever did see. With that as a model, the Amies turn regular mosquitos into the less evil version in whatever numbers it takes.
Promise puts her mosquitoes in a box, turns it and them invisible, and hopes the mystery idiot's description suffices for a gate.
It does. Lucky mystery idiot. She steps through.
He, like all the fairies around him, has no idea she's there.
