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 -
"Or...whoever you call on when threatened.
You know what, I'm here to forcibly collect all your names. Please raise the alarm and have people try to stop me."
"I am Eidolon! Face me if you want to keep your names!"
Is this what it's like for his opponents all the time?
The court up the mountain has homes dug into the mountain, perched up trees, in mounds of earth on the slope, and in a few gigantic flowers. The presumable home of the court's master is a fancy building with lots of glass and shells; someone peeps out of the window, then disappears. A minute later fairies of various shapes and sizes and colors fly out of the fancy house and address others in the court. Apparently getting a court ready for unexpected challenges like this takes a while.
In a few minutes he'll be fully prepared for whatever they throw at him.
The cold isn't going to be literally everywhere; he considers locations to teleport to until one of them doesn't involve being frozen. With any luck he'll be in blasting distance of his opponents.
This is enough of a move against him that his precognition tells him their path, but that doesn't make it a threat. He appears in the middle of the buzzing and strikes at them with telekinesis. One fairy gets a small piece of mortal fruit blasted toward their face, stopping before it arrives. "I'm looking for people who can fight me. Where are the sorcerers?"
The inches disappear, and the pomegranate seed starts pressing itself through the fairy's mouth.
"Where are my opponents?"
The problem with these parahuman powers is that they tend not to work on things inside other people's bodies. He forces her mouth open with yet more telekinesis, and flies the seed down her throat until his power is no longer able to affect it.
Swap with a different anonymous space, try again with five more pomegranate seeds, juice them first, same orders.
"Thank you." Invisibility, of course. He casts around for a power that would let him detect invisible people, and gets a density manipulation ability that highlights where an object is more or less dense than its surroundings. He doesn't need the teleportation; this telekinesis can do double duty now that it's at full power. He blasts out from underground, setting the fairy down beside the hole. He starts attacking invisible fliers first.
At least sorcerers' magic isn't going to be definitely useless later. His second objective can still be a success. He switches to trying to force-feed them crushed fruit seeds.
