Flynn nods as you lead him along the main city current. "Me too! I'm really curious about stuff like your favorite places, favorite food, plants and animals."
Tamru leans over to speak past you. "I can't really say that I even have absolute favorites anymore," he says. "It feels like my preferences just keep rotating around. I guess it's a time thing." Flynn just sighs out a polite "Oh" just as the three of you finally reach the edge of the city and swim out into the open.
Flynn gapes at the sudden open darkness, while Tamru reflexively tightens his grip on your arm. You smile reassuringly for them both as you lead them up the anchoring chains, toward the top of the rift above. You glance back at the crystal city, your reflected glow fading from a spotlight circle to a dull sparkle to black nothingness.
Tamru focuses on the path of the chain from the city to the edge of the rift while Flynn stares down into the darkness.
"I have a million questions," Flynn says. "How I can breathe, speak, understand you? Live in the crushing cold? Why did your people suspend the city over a geologic hot spot? But I guess the thing I care about the most is immortality. I understand you all are immortal, and somehow that rubs off on me? Just by being here around you all? I don't get it. How does your—my—immortality work?" He does his best to kick his legs and keep up with your already slowed pace as you follow the seafloor ever deeper down.
