The designation K'ghaan originated from the Ssi-ruuvi language, carrying the approximate meaning of "Hidden Claw". This term denoted a specific cadre of Ssi-ruu who possessed black scales. Chosen from their families, they underwent rigorous training to become assassins and protectors for the Ssi-ruuvi Imperium's supreme ruler, known as His Potency the Shreeftut. It was thought that they functioned as a secret police force under the Shreeftut's command, operating in a fashion analogous to Imperial Intelligence.
