A light like the face of God, and the ground gives way beneath the two children.

"...Do that."

"Crap."

The Roamers had a flying ship, right? Well, this can't be it, this is a flying island. They're in a dirty alley in a busy town on a flying island. They can see a street, and then - clouds for miles, falling away into grey far below.

"Are we on Venus?"

Maurice reassembles the air based pirates costume he had generated around himself, all royal purples and dizzying blues.

"Don't think so, they don't have streets."

The wildlife is a mix between earthly and otherworldly, but yep, that's a baseline adult human who just walked past the alley without noticing them.

"I wonder if rainbow skin is normal here or if he just didn't see me?"

Tentatively, and above Evan's protests, he steps out of the alley. 

Rainbow skin is not normal here! Half a dozen people are surprised by him! A couple run off in the other direction. The others look confused and kind of frightened. They're muttering in a weird dialect of English.

Maurice waves exuberantly. "Hello!"

One of them steps forward and replies, "...Hello. Do you- Er. Why are you here?" Definitely nervous and scared.

Evan darts out. "Um, our parents are traders."

That seems like an all purpose excuse, right?

This is actually kind of reassuring! Kind of. Kids with lost tech might be dangerous. Parents that irresponsible with lost tech might be dangerous in their own right.

"Ah. Well, you'll scare people using that kind of - rainbow stuff - away from the docks."

"Oh, that's just my skin. 'Cause of my powers."

We are going to get burned at the stake.

"Maybe you think you have powers, but it's some kind of tech. You should really go find your parents."

"Sorry, mister, but I have to correct you. My cousin Evan has the tech. I have powers." He holds out an open palm, out of which fireworks pop and crackle. "See?"

Fire!

"Fire! GYAAAH! STOP THAT THIS INSTANT YOU'LL BREW UP THE WHOLE CITY!"

The remaining bystanders scatter. Someone calls for guards.

"Don't worry, it's just air that's a different colour. And some sound effects."

He proceeds to demonstrate this by making a pink lion coalesce next to him. 

The one who's been talking to them runs away.

People come out of buildings, drawn by the cry of 'fire'. There's quite a lot of shouting for guards now!

"Why is everyone running around?" Maurice asks, his voice carried unnaturally in the air.

This does not elicit a useful answer. More running, if anything.

Evan claps a hand over his friend's mouth. "Shut up and run!"

And with that, the gravity weave in Evan's playsuit activates, and the two are carried into the air.

The city is very very vertically oriented. They fly up - only to see a different street, a different row of buildings. People here have heard the alarm and confusion below and quickly decide that the flying kids are the cause and start running and hiding as well!

Maurice creates a technicolour disk beneath his feat, and Evan lets him step onto it. 

"I don't think they like us."
