Mika is a bustling trade city, built around both sides of a magical Gate.  The tall archway is around a hundred feet across and perfectly circular, though the bottom third extends underground.  

In the blink of an eye, the gate in East Mika flashes and suddenly shows a new scene.  A few carriages which were about to cross through make their way to the new other side, milling about in confusion as the paved cobblestone road suddenly gives way to grass.  No one seems to have been hurt though one unlucky carriage was bisected, the back half falling forward and spilling corn everywhere.  

There's some alarm from the people currently watching the goats.

After a few moments, one approaches, cautiously. She's a teenage girl, hair dark purple, skin pale, eyes a lighter lavender. Her hair's pulled into a messy ponytail, and she's dressed in loose clothes with a broad cone hat to block the hot sun. She calls out something.

The gate is chaotic, but some city guards were quick to respond and start ordering everyone back into the city.

One, an older woman, seems to be in charge.  Her asymmetric uniform is trimmed with gold and the insignia on the right shoulder has been expanded upon several times.  She calls out in her own language.  

The girl seems confused and wary and does not understand that. She keeps trying the same language.

The guardswoman calls for one of her subordinates to go find a priest with a translation sorcery.  Just in case one works, she tries a few more languages in the meantime.

Nope!

One person's staying near the fence, and the girl's staying near the portal, but the other one who was in close distance when the portal opened is heading back to a cluster of farm houses, and there are people emerging from the houses.

A man in elaborate robes of layered green organdy is brought forward.  

"Hello.  I have translation magic, and will be able to understand your language.  Do you know what caused our Gate to change locations?"

"That wasn't on your end? We didn't do anything."

"Mika Gate has been connecting the two sides of our city for centuries.  I've never heard of it moving, nor anything that would cause it to."

"Well, we haven't, either. Even the shinobi don't have weird giant gates."

"What's a shinobi?  It isn't translating."

"Ninja? One of the types of magical people, I guess. They're the local ones. Mercenaries and all."

The man turns around to ask the guards if they've ever heard of that magic.  They all shake their heads.  

"It doesn't sound like one we have."  That isn't too surprising.  Mika is a major trade route through the southern half of South Cardinal, but doesn't get a ton of traffic from elsewhere in the world.  

The guard captain asks something, and the green-robed man translates.  "What country is this?"

"Land of Fire, east coast of the Elemental Nations."

Some more debating between the translator and the guards.  

"We haven't heard of your country.  

"Mika is its own city-state, within the borders of Wikara and Mikiara, on the continent of South Cardinal."

"Haven't heard of any of that, either, but I guess I wouldn't've."

There are no other immediate questions for the girl, but the translator is ordered to stick around. 

The guard captain shouts at one of her people to bring some maps, then turns her attention to checking over the blockade around the gate on their side.  There's a crowd gathering behind the hastily-erected barriers, noisy and confused.  

And there's a team of shinobi - four, two of them roughly teenagers, two older - approaching. They land in the field, watching the gate warily.

A guard spots them.  

After a moment, the guard captain removes her sword belt and hands it to one of the other guards.  No reason to go armed and possibly cause a misunderstanding.  She motions to the translator, and they walk towards the newcomers.  

"Who are you, and what is your purpose here?" the one in the lead, a man with dark red hair and skin only a bit darker than the girl's, calls.

"We are the people of Mika City.  Our city has a Gate which connects its two halves, which are on opposite sides of a mountain range.  Something made the Gate send us here instead - we don't know what caused it," the translator summarizes.  

"Where is Mika City?"

The countries of Wikara and Mikiara, on the continent South Cardinal," the translator repeats.  Maybe a shinobi will recognize the locations.  The guard turns around to see if anyone new is at the gate, but it looks like her request for a map hasn't come back yet.  

"Haven't heard of them."

He sighs.  "Yeah, neither did the farmer.  We're waiting on maps, but it's likely we aren't on the same planet if you've never heard of the Cardinals - they're the two biggest continents."

There's some more conferring with the guard captain, "Do you know of anything here that might have attracted the gate to be pulled here in particular?"
