Krypteia

The Krypteia is the secret police of the Mantis Lords, used to police to subjects of these nobles. Agents of the Krypteia are always human, though their identities are concealed. Krypteia agents can be either noble or commoner. When ordinary law enforcement (usually the human-commoner militia organized by the local Mantis Lord planetary or solar-system governor) fails to deal with anti-Mantis Lord dissent, either members of alien races, adherents of outlawed Solar Church of the Unconquered Sun elements, or pro-democracy and alien-rights advocates who want to mimick the examples of United Republic of Earth or House Lionheart, and in case the Mantis Lord-dominated amed forces are too busy dealing with foreign threats, the Krypteia steps in to take care of things, including arbitrary arrests, torture, and even violence.
