Down on the very lowest level of the Coruscant underworld, Raan Crossfitter knelt by the outflow grate and dipped his VOA specimen container into the murky …substance. He was hesitant to classify it as water, or even water based. It behaved more like tar and smelled like a bantha's asshole, a comparison he wouldn't have known how to make a mere week ago. As he delicately scooped the gunk into his sample container and carefully marked it in his own notation, Raan eased back onto his weary haunches and considered what a crazy week it had been. How not long ago he had been sitting in a stuffy Brooklyn conference room, doodling aimlessly on his legal pad while the EPA bureaucrats on speakerphone droned on about the Newtown Creek CSO reference area.
Had he dozed off? Suddenly the wall of the office had been blown away, alien beings storming in, little wheeled robots beeping and booping as they followed. Thankfully he had muted himself so the EPA types wouldn't hear his insulting responses, and they were none the wiser to the strange scene that was now occurring in this very room. One of the aliens growled something at him, and immediately a prissy looking gold android stepped forward and explained in a starchy British accent that these beings were bounty hunters, and that they had come to find the greatest Environmental Engineer in the galaxy, and that he was it! Ron could hardly believe it himself but secretly had always suspected it to be true. They also needed that person to be a galaxy-class athlete, as there was sure to be lots of adventures ahead with running and box-jumping, and were very impressed by his social media.
Raan had been given a simple mandate once the oddly metro-acting protocol droid finished translating the weird hoots and whistles that the alien had laid out for him. Corucsant was suffering from carcinogenic pollution that seemed to grow worse the lower down you got. Raan's job was to collect water quality data of the combined sewer outflows, perform extensive modeling, hold public meetings and analyze potential projects based on costs and anticipated water quality. He ran his fingers through his glistening locks of hair as he mused over the possible causes of this pollution after getting more details on this planet. From the way he heard it, the whole place was one giant city, buildings stacked atop one another miles and miles into the sky.
All of that runoff – starting from the particulates precipitating out of the atmosphere high over the superstructure of the city-planet, to the TIE Fighter factory industrial runoff on level 405, the illicit deathstik manufacturing center likely operating somewhere in the building core below it, never to be found, the trillions of gallons of residential sewer mains all connecting to one another in larger and larger bores as they traveled downwards and yet still miles above the nature surface of Coruscant.
It didn't take a galaxy-class Director of Superfund and Hazardous Materials (even if Ron was one) to see that the whole damn planet was one giant combined sewer outflow.
