The Treishya were a group within Andorian society. In the 24th century, the Treishya believed that their society had decayed over the years. Since its formation, it operated patiently and worked in the shadows in order to increase its ranks whilst remaining out of sight in the eyes of the government or law enforcement agencies. It consisted of both civilian along with those with ties to the military. To the general population, it was believed that the Treishya would only have a short existence and operated on the fringe of vocal activist dissenting groups such as the True Heirs of Andor.
