And he teleports a couple hundred miles over, asks the first people he sees in which direction he'll find Voa's capital. 

These confused purple-haired sun-browned people point vaguely thataway.

He repeats the exercise!

Eventually he can find the capital.

He really misses being in summoning range. Now he starts asking after administrative buildings.

You take the 6* train and get off after four stops.

Flat Elves could just ask what it looked like, read their mind a tiny bit, and go there. - he could ask them to pull up a picture for him? He does that.

Sure, a friendly yellow lady will show him a pretty picture of the capital building.

It's not pretty. He teleports on over.

It's a little pretty, although the surroundings aren't helpful.

He walks inside. 

Blue and yellow people bustle to and fro. The receptionist says hello.

"Hello. We sent out messages introducing ourselves but you seemed to be having some technical difficulties. Is there a better format for an introduction?"

"Oh, we're under radio jamming - we heard about you secondhand - I don't think anyone's been assigned to greet you if you just, ah, show up, but I can send a priority alert."

"I appreciate it."

And a minute later an old blue-haired woman comes down the elevator. "Good afternoon. I'm Governor Avalor."

"Macalaurë. I apologize for just dropping in."

"You could hardly have announced yourself. Welcome to Voa. How can I help you?"

"I'd be delighted to have a channel of communications, to start with, and past that it's really up to you. I represent one of half a dozen interstellar consortiums that might be of interest, though the Tapai thought our membership conditions were onerous, and we're excited about the potential for colony planets to relieve some of your population pressure."

"I expect Voa to be excited about that too. My office is up this way."

He follows.

Here is her office. "What are your onerous membership conditions?"

Computer chip. "We translated everything and converted it to local file formats. The condition that caused them the most concern was the requirement that laws apply to all citizens unless supported by a majority of the citizens who are subject to them."

"I assume the sticking point is that this extends to red caste."

"No one's yet tried to make the case that they're not relevantly citizens."
