The Orions were a humanoid species originating from the planet Orion, located in the Beta Quadrant.
Orions were known for their distinctive green or blue skin. Orion males were typically bald and, on average, taller and more muscular than the average human. Orion females were very "animalistic" in nature, known for their extreme carnal appetites and their innate skill of seduction. Orion females could give off highly potent pheromones which accelerated the metabolisms of males of many species, raising adrenaline production to dangerous levels which caused aggression and, ultimately, a form of delusion. Its most significant effect was to make them susceptible to suggestion. Females of many other species were adversely affected.
In Orion society, the males were slaves to the females. As a means of deceiving other species, the Orions maintained the facade that the females were the slaves. This was commonly done by selling Orion females on the Orion slave market. Orion itself presents itself as a neutral world with a long history and once home to an advanced civilisation and as such has established links with many worlds.
Orions though are famous for their criminal Syndicate, an organization associated with the race that is known for activities including gambling, racketeering, smuggling, piracy, slave-trading, extortion, and assassination. Orion technology is roughly on par with the interstellar standard with the ruthlessness and cunning of Orions operating the technology a greater consideration in establishing its comparative worth.
