You decide to head along the branch, it'll give you time to get a good view of the city. The road just curves around, heading up a shallow incline and then back down, merging with the buildings near where the huge mansion is, on the far side of the city to where you are.
As you walk, you just stare at the Underground City. It's a hell of a sight, all those buildings and walkways, fine tendrils of smoke rising, hustle and bustle of people.
You try to peer closer. Something isn't right, but you can't quite put your finger on it. The small figures moving back and fourth in the city streets don't look quite right somehow.
Suddenly you become painfully aware of how exposed you are up here. You're in plain sight, clearly looking down at the city, but thankfully none of the inhabitants are paying you any attention. Maybe visitors here aren't as rare as Parsee's hostility made them out to be.
As you carry along the road, the orange glow towards the rear of the city intensifies. It lights the walls of the cave, far off in the distance, and makes the huge mansion throw a monolithic shadow on the ground. At the edge of your hearing there is a deep, bass rumble, hot and fiery and full of power and fury.
You stop before the roadway curves back towards the city.
"This is the weirdest place." You mutter to yourself.
"I know, right?"
You jump out of your skin at the voice, twisting around to see where it came from.
"H-hello?" You say.
"Hi!" The voice comes again.
"Who's there?" You keep turning on the spot. "I can't see you, where are you?"
"Hahaha." The voice breaks into amused, but good-natured laugher. "Of course you can't. Don't worry about it!"
"Are you invisible?" You ask, eyeing the various stalactites and small boulders in case one of them turns out to have a mouth.
"Noooooot exactly. But nevermind about that now. What's a human doing in the Underground?"
"I just ... fell down here." You say, peering over the edge of a boulder, looking for the source of the voice. It's maddening. Not only can you not tell which direction it's coming from, you can't even tell if it's male, female, young, old, anything. It's as nondescript and forgettable as you could possibly imagine.
"Fell down here, huh? Me too, kinda." The voice says.
"Who are you?" You ask, stopping on the spot and giving up your search. Whoever it is, they want to stay hidden.
"I'm nobody, it's not important. What is important is you and that bag of tricks you've got there!"
"Bag of what-a?" You glance at Farley's backpack, still slung over your shoulder.
"Oh you don't even know! You're worse than I thought."
"Look, human. Bottom line, you're fucked. You're fucked so hard you're not gonna be able to see straight for weeks afterward. You are in so much trouble, just being down here is trouble if you've got nothing but that adaptive learning and tool-using you things are so proud of."
"Uh ... huh. Go on?" You swallow. Maybe you hit your head too hard on the way down, maybe the air here doesn't contain enough oxygen and you're hallucinating, but at least the hallucination is friendly.
"See I was just gonna have some fun with you as you were passing." The voice continues. "Then like, woah! He's just a human! You need help, okay?"
"Like survival help. A little, er, boost to get you on your way. Nothing special. What do you say, huh?"
[ ] Just leave, keep walking, you're going insane.
[ ] "Sure, what kind of help?"
[ ] "Only if you show yourself."
[ ] "I think I would rather not owe you anything, crazy voice in my head."
