"Gosh! What kind of magic? ...Did you make a good first impression?"

"Awesome magic. I did not light any locals on fire."

"I might need to know more about it to travel there!"

She sends! The city is incredibly pretty, pretty enough for any Elf, all graceful metal and glass buildings so tall the tips get lost in the clouds, and there are people with bat wings and bird wings flying and people with bug wings flitting around like insects and the streets have Elves and humans and Dwarves and not-quite-humans-they're-jumpier-and-all-have-red-hair - 

"...well. Wow. Thanks for all the scouting."

"Anytime, sweetheart - oh, I tried to come right here to tell you about it and it didn't work, I think maybe it was too far? I got there from the empty planet and I had to go back there to come back here."

"No sign of Sauron?"

"It's a big planet and I haven't been looking - okay, once or twice - but anyway no signs of Sauron."

"I guess no news is good news."

"It's not bad news. Anyway I'm gonna go back to the flying humanoid menagerie planet and poke around more. I won't, like, officially say hi, you should do that if you wanna do that."

"I might!"

Poof.

Cor goes and finds Findekáno in his treehouse.

"Hey!"

"Hey. Mage Thuringwethil found an inhabited world with all kindsa people and ridiculously tall buildings. From the empty planet; she can't reach it from here."

" - huh. I am reluctant to show up all coated in blood lest we scare them - maybe if we land a ways away and do the cargo version so we can take clothes -"

"And a bucket of water and rags, yep."

He hops down from his treehouse. "Right now?"

"Unless you're busy."

"I am, it happens, not busy." And they collect sheep and bucket of water.

Cor takes them to a spot vaguely between points seven and ten on the empty world and then to the place Thuringwethil showed them. Doesn't even need to repaint.

The city's more stunning in person. Stunning, meticulously planned, dense - seventy million people could easily live right here. It appears to be an even mix of Elves and humans, with a sprinkling of the Dwarves and winged people and other, even stranger things (a blue centaur with stalk eyes and a bladed tail walks down the street, and no one seems to think anything of it). But the Elves clearly got to call the shots on the architecture. 

"They're speaking several dozen languages," Findekáno says after a moment, "and one of them is Quenya."

"...that's... weird... I never got to be good at Quenya, I guess you can translate?"

"Yeah - I'm not sure how that happened in the first place -" Frown. "Also the Elves are keeping private thoughts but very few other people are."

"...weird. I guess possibly strategically useful if they turn out to be hostile for some reason?"
