The Clan of Enforcers were an intelligence agency within Andorian society before their entry into the United Federation of Planets.
They were operating on Andor several decades before the signing of the Articles of Federation. They served under the Andorian Council of Clans and the Star Empire of Epsilon Indi. While not directly associated with the military, the Clan of Enforcers often worked with them in joint operations. Most of the Clan joined Starfleet Intelligence after the Andorians officially disbanded the organization though there are rumours that the Clan of Enforcers still exists but only through the support of a few Andorian operatives.
