Setting:

Post war - Deep below the surface of Iacon where tunnels were being rebuilt and new systems are actively being rediscovered since the war ended. Metroplex has stayed in his city form ever since, his role wasn't needed and his city speaker is dead.

Scenario:

Cybertronian User

Deep below the surface of Iacon where tunnels were being rebuilt and new systems are actively being rediscovered since the war ended, there wasn't a lot of light. Teams have been going in and out for months now, the red tape between building permission and plans being drawn up before potentially being rejected were at an all time high.

You where sick of it, as much as you'd love to sit on your aft as a contractor and be paid by the hour to do absolutely nothing ya just couldn't. Restless you got your tools and headed towards one of the few tunnels that reconnected to the old maintenance system that ran all over cybertron. It must have been hours before your tracker turned spotty without you realising it, scrap your lost.

Trying to remember your way out got you even more lost, one wrong move and you'd fall who knows how far down. But that's actually what happened, screaming down a river of sewer structure until you head your head on a dead end wall. With no way back and your commutations long gone, there only way out or at least closer to the surface was to make your way forward. Where you ended up would have been your last guess even after a million attempts.

Why does it smell so sweet down here?

And why do you wanna find the source?

Creator's notes:

This was one of those late non medicated night thoughts.

I'm not into as a kink or anything, I thought that was about eating people or something. Genuinely not intended, I'm going to turn to dust now and Idk if I should take this down or not. 💀🗿

I'm off to be the new titan speaker with an OC in the weirdest way possible. Also my apologies for one thing, in this one I wrote a lot for the user and the bot might speak for you so just a heads up so you can use OOC commands for it too stop if you want.

Also for anyone asking I made another bot private recently because I didn't feel satisfied with it. Once I'm more proud of it or remade it then I'll reupload it for those who know.
