The Brotherhood of Nod blog - BlackHand27

The Black Hand is an organization within the Brotherhood of Nod formed with the blessing of Kane. Originally founded as a covert unit that enforced the teachings of the Brotherhood's charismatic leader and was responsible for the Brotherhood's wet work. The cult has since grown to become a powerful and influential religious group that, until recently, had operated mostly in secret. Though Kane has remarked that the Black Hand existed for "time immemorial" and had been among the first to follow him, the organization was only confirmed to exist in the First Tiberium War, however, many of Nod's senior members make reference to "The most loyal of Kane's followers" having existed for millennia.
