Enlightened Ones

The are a faction of former shinobi who left their hidden village in order to join the revolutionary Gengo following the aftermath of the Fourth Shinobi World War. They were primarily made up of young, single men but they were willing to accept women into their group. Like the Akatsuki, they are dissatisfied with the current system of shinobi; they seek to replace the current ruling class of normal people and put shinobi in control of the world.
To that end, they offer missions at significantly lower prices than the competing Shinobi Union. They had even infiltrated each of the Five Great Shinobi Countries to cause an incident among their population and destabilise the Union itself; all at Gengo's command.
Enlightened Ones are characterised by the long black cloaks they wear and their vehement loyalty to Gengo; many whom were placed under his voice-induced genjutsu into becoming his obedient subjects. They have based their operations at the Land of Silence, where Gengo reigned after deposing of the previous daimyō. 
The Enlightened Ones were ultimately disbanded after their leader was apprehended by a coalition of Konohagakure and Sunagakure shinobi lead by Shikamaru Nara and their brainwashed members were freed from Gengo's control.
