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 -
"And you frequently have people threatening others' lives, whose names you want to hand over to me, who will listen to me telling them not to kill anybody? This is a routine problem you have."
"And in the unlikely event that your name thing works on Endbringers, you could be the most important asset the world has. Bar none."
"Every few months, one of three city-destroying monsters attacks and capes fight it. Heroes and villains call a truce, strictly enforced. We evacuate as best we can, but thousands of civilians die. Your ability offers an outside chance at being the only thing that can stop this entirely."
Even if you can't control them, we are currently reliant on a handful of capes to transport the entire defending force to the battlefield. Depending again on how they work, your gates could make a valuable strategic difference."
"Gates can sometimes take days to settle. And going through Fairyland would be dangerous for you."
"Low speed would make it less effective. Do fairies or sorcerers have any offensive or defensive capabilities?"
"There are a lot of kinds of fairies. I'm pretty harmless as far as natural weapons are concerned, but there are some who have other non-sorcery kind magic which could be hazardous, and sorcerers can do a lot of different things, which I am not presently inclined to list."
Emily glances back at the screen. "It looks like an improvised testing ground for your sorcery has been set up, and Vista is on site. Follow me downstairs?"
Promise settles her bag around her shoulder - it didn't burst or anything when she was shoved, but it did jostle - and follows.
The improvised testing ground is an unremarkable door halfway down a hallway. It opens onto a round empty room wider than the building. A single bulb in the center of the ceiling is entirely insufficient to light it; extension cords from outside allow other equipment to fix that problem.
"This was a closet a few minutes ago. It is under the effects of Vista's power significantly more than anything she would use in the field, so if that's the relevant factor your abilities should work here."
Vista herself is in the center of the room, smiling.
"Thank you," Promise tells Vista. She scans the room for sorcerously relevant things. A lot of light sources, but she can work with that. To make sure that this isn't going to be a completely wasted attempt at a gate, she first makes a fairylight, too, hovering above her hand; when it doesn't disappear, she nods to herself and then says, "I should probably mark on the floor where the gate will be. How do you prefer I do that?"
"Whatever non-destructive method is easiest. It's an unimportant room in every way not related to sorcery. Are there any mundane supplies that would help?"
"A pen or something is fine. The sorcery doesn't care about the marks, it would just be so no one wanders into Fairyland by accident. I'm planning to put the gate a mile above the ground, by the by, so I don't recommend that anyone who can't fly follow me even if they want to see the place."
"I could, if you don't want me to come back after all? I suppose while it's settling you could tell me the Endbringers' names and I can see if they count."
Piggot answers, "The Protectorate would be happy to work with you, you just gave the impression of trying to get away and, presumably stay away. I'll make sure this area doesn't get set back to normal.
The Endbringers are Behemoth, Leviathan, and the Simurgh. Would you know if that did it, or would you need to meet them first?"
"...I would need to know a little more about them. Besides that they belong in this category. I don't have to encounter them in person."
"That's easy enough." She takes a small rectangle out of a pocket, pokes at it, and in a few seconds is showing Promise a Wikipedia page describing Behemoth. Forty-five feet tall, externally appearing to be made of magma and obsidian, capable of manipulating all known forms of energy, and with a habit of killing capes en masse. A picture accompanies the text, and the full page is very long.
"Not his real name, for this purpose. Or doesn't count as something I can take as a vassal."
"I can try the others. Or if he may have been called something else first, that might be what counts as his real name."
"Alexandria called him that when he first appeared, if that matters. If there was an earlier name, we have no way of knowing." But she shows the descriptions of the other two anyway.
