Orions

Slave traders who dealt in “green animal women.”^[1] The supposed “animal” nature of Orion women, however, was discovered to be a pretense by the Enterprise NX-01 in 2154; Orion women produced extremely powerful pheromones, which they were able to use to disable Human women and make men—both Human and Orion—susceptible to suggestion. Vulcan women were apparently immune, while Denobulan men were sent into an unnatural sleep cycle.^[3] Orion territory was located adjacent to the Klingon Empire, and the region where Klingon and Orion territory met was known as the Borderland.^[2]
