Orchid's mind control is a very lucrative business in the world of the 22nd century. As nations struggle to maintain order, and keep their sovereignty, due to the changing geography of the planet, they see themselves with nearly unmanageable numbers of inhabitants inside their increasingly blurred borders. Some countries prefer not to rely on this unethical tech, but many others just see it as an effective way to form loyal and reliable armies.
There is one caveat to this tech, it requires a subject with a very high level of sexual motivation. In order for the mind control to take place, it needs to adhere itself to the body needs of the user. It uses the desire for sexual pleasure and amplifies it greatly. The mind then is taken over by sex thoughts, but immediately after they are condensed in the conscious mind, they are quickly turn into subconscious thoughts. This technique was discovered to increase the ability of the host to perform its instructions with more efficiency. Previous attempts without this technique resulted in the user not being able to rationalize with ease, due to the flood of conscious sexual thoughts.
The moving of sexual thoughts from conscious space to subconscious space has still some unwanted effects, chief among them is that when the subject is put through a small sedation, or a general slowing down of the metabolism, the gate that kept the sexual thoughts from taking over is abruptly opened, and the ability to control the user's mind is temporarily lost.
