Nick was born to a family of Politicians on Mars, the capital planet of the Federation. Since the Federation's ideology went against those of Nick's, he tried his hardest to get out as much as possible, at the age of 19 he succeeded.

Nick found an escape with a crew of smugglers who trafficed Onionhead into Federation systems. He wasn't happy about doing illegal things but at least it got him out of Federation space, for the most part. It wasn't long before he was flying his own Cobra Mk III, until one fateful day when the crew made a deal with the wrong people and soon they were on the run from the authorities. Nick managed to escape, but with the rest of the crew captured, he didn't know what to do and with the authorities on the look out for his Cobra Mk III he decided to hide it and buy a new ship. Only able to afford a small beat up Sidewinder. Deciding that smuggling was too risky, he decided to switch to trading. Trading paid alright, not as much as smuggling Onion Head but it allowed him to slowly upgrade his ship, and after a while he was even able to afford bigger ships. One day, an old client from his smuggling days reached out to him after hearing he was in the trading business now and asked him if he could pick up some rare goods and so Nick entered the rare goods business. It paid more than normal trading and allowed him to meet some interesting characters. It wasn't long however before Ukumio found his way back into smuggling however.

One of his buyers tipped him off on a little known secret place that was on the outskirts of the bubble that sold slaves to the rich near the center of the bubble. It wasn't a morally clean job, but it paid a lot. Nick was sick of hunting down rare goods for a small profit so decided it was worth it. Someone was going to do it anyway so it might as well be him. For three weeks he made the run from the outside of the bubble to the center and back again, and in that small time he earned almost 500 million credits. This is when Nick's life ended.

Apparently, his old smuggling crew had finally been released and were upset that he hadn't tried to bust them out in the 2 years they were held on a prison ship. Wanting to fall off the grid in order to escape his old crew, Nick changed his name to Ukumio and headed off to Colonia, a brand new bubble of Humanity that was beginning to form over 20,000 LY from the Bubble. With nothing but his smuggling ship, now refitted for long distance travel, he headed off. It was in Colonia that Ukumio found his true calling: Mining. Being a new society, mining was one the best ways to make money because what does a new society need? Building materials, and it was too expensive to ship them the 20,000 LY from the Bubble. Ukumio loved mining. He hired a small crew and mined for hours.

After a couple months and with his new identity intact, Ukumio returned to the Bubble. He continues to mine, rarer metals now of course. Keeping his head down and always on a swivel in case he needs to make a break for it again.
