Never managed to get into one of these mission ones before, would be awesome if I have the time for this.
Here are two characters, since the first would be perfect for this but I already used it for another game, so I'll leave it up to GM discretion.
Character Name: H
Origin: Unknown
Bio: Very few know of H, and even they know next to nothing. What they do know is that H is very good at what H does. At all times, H seems to wear a fairly standard-looking white pressure suit, of humanoid fit, with a seemingly opaque visor. When not on a job, H is observed to hand around bars, auction houses, and other places where travelers seem to congregate, doing absolutely nothing. It is here that those in the know (or who simply guess) approach H. They name the task they wish performed, describing in detail, and then offer H a price. If the price is sufficient by whatever standards H judges, H will carry out whatever is asked. If not, H will merely ignore the offer. No one knows what H does with the payments, having never been observed to spend anything. Some say H feeds on it somehow, others believe it all to be hoarded somewhere. But only H knows, and H never tells anything.
Specialties: Spacewalking, Sabotage, Stealth, Silence, Hand-to-hand combat, Setting traps.
Character Name: Atlos
Origin: Being an aquatic species, the Rtalis took a very long time to develop space travel, and continue to struggle with the engineering problems of their comparatively dense water-filled spacecraft, but this has left them better adapted for microgravity environments than many other species. The thrill of exploration dating back to their forbears who explored dry land lays deep in their culture, and continues to drive them to explore the universe and encounter other peoples. Atlos is one such eager explorer, having roamed the cosmos for (by human standards) decades now, though that includes dormant travel time. Rtalis have an eel or serpent-like bodyplan, a dozen short but dextrous limbs along the length, and surprisingly expressive faces. Their natural modes of communication are through sound, body-gestures, and bio-luminescent displays, though when interacting with aliens they primarily use sound.
Bio: Atlos has always been fascinated by alien peoples, and has a passion for studying and immersing himself in their cultures, though he feels somewhat isolated from them by the fact that they are all mostly gas-breathers or otherwise averse to water. He is somewhat well-traveled, and considers himself a cultured person by now, but is always eager for new experiences and adventures. Often has to travel in a bulky mobility unity, basically a glorified fishtank on treads, but feels confined when spending long periods of time in it, and likes to sneak into and explore the plumbing of air-breathing facilities.
Specialties: Cultural knowledge (leaning towards "high culture"), Diplomacy and persuasion, Swimming and fitting into narrow places, Vehicles.
