"Here we go. If I'm not back in three hours, assume something bad has happened to me."
"Close the gate is what I was thinking, lest the war come through and spill into fairyland. If you abandon me to the ravages of my world and don't let fairies get involved, it can't get much worse."
"Noted. I might open the gate sometimes when I happen to be able to keep an eye on it, in case."
A sigh. "War is dangerous. I won't go looking for trouble, but I need to figure out what's going on." Without waiting for a reply, she steps through the gate.
She's back in two and a half hours.
Promise is waiting for her. "Do you need healing again? What's going on?"
"I'm fine this time. There wasn't anybody in the area where the gate leads, but one of the sides has set up extensive fortifications and patrols in the farming area to the north. The town goes by the name of Teth. I listened to a pair of travelers, they wanted to enter Teth as refugees. The patrol that approached them acted friendly, and they set off for the town together, so I have hopes that this faction is somewhat friendly."
Steel has become a decent sorcerer with good finesse, at least for someone who's only been at it for less than a year. It's unclear whether she'll be able to help Promise in figuring out invisibility, though - her magic scholarship is mostly bluestream.
Promise takes hours, but not days, to work out how to turn herself invisible. She cannot immediately turn Steel invisible, but she can describe the self-invisibling process for her.
She gets it eventually, though. After a sleep, but before she runs out of food.
"Nice! I think we can do this in anything but fog or dense tangles. Am I going to go scouting alone or do you want to come along this time?"
"If the area's safe I'll come along." Promise packs some food. "But not too close. I don't want to hear any names I don't need."
She does that, and is back in about five minutes.
"The local area is still abandoned, though the harmonics are all fog. If the invisibility wears off, neither of us will stand out with the wings" (she still has hers) "except that everyone will assume we can use the bluestream. The roads are still in good condition, harmonically speaking, and the town is still intact as far as I could tell from a distance."
"It shouldn't wear off particularly quickly, although I don't know exactly since I wasn't working out of a book. Will you make a sound or a fairylight or something so I can follow you while you're invisible?"
"Alright, but clearing the fog enough to make a fairylight tolerate existing will make me a little slow and clumsy. I'll mark off every twenty feet or so."
"You could also just whistle occasionally. Or I could peek at the bluestream to see where you are."
Nothing visible happens, then, "We're mostly invisible in the stream as well as physically, right now. You can still see the eddies we're giving off, but it looks like we're - ghosts, or something. You wouldn't be able to find me in the fog, so I'll just stick with occasional lights."
So she goes through the gate, and walks down a steep slope covered in shrubs, trailing the occasional fairylight that sticks around for a few seconds before disappearing. A few of the shrubs rustle. Some berries on them float and then disappear, presumably invisibility extends to them once they're eaten.
Steel's chosen path takes them downhill for a while, and then to a small road made of dirt and barely holding its flight-friendly harmonics together. She makes an arrow pointing north from fairylights and a sort of fluttering wings-shape - 'Time to fly, speed up'
Promise follows her, looking at the world around them curiously. Even the presence of the road is peculiar and interesting.
They don't see any people for about twenty minutes. Then, Steel's lights spell out 'HIDE'.
In about twenty seconds, the shape of a sizable group of humans approaching along the road starts to be visible in the bluestream. They're still on the other side of a little hillock, physically.
Promise flings herself into a densely-branched tree and crouches invisibly there.
They pass Promise and Steel's hiding spot without so much as a glance. When they're well gone, Steel's fairylights ask, 'Continue or go back?'
It's also heavily guarded by dozens of soldiers behind stone barricades, with harmonic patterns that Steel identifies as combat magic. I didn't get this far last time. I don't think we can sneak through. Looks like we'll have to introduce ourselves, or go around. Your thoughts?
