Salem's Faction

Salem's Faction is a group of people aligned with Salem who are aiding her plans and serve as the main antagonists of RWBY. While their objective is not clear, it involves the destruction and downfall of civilizations across Remnant. It's also revealed they've been hunting down and stealing the powers of the four Maidens, though to what end is unknown. The group is closely connected to the Grimm, as their headquarters is located at a desolate spawning ground for the Creatures of Grimm.

Known members of the group include Cinder Fall, Doctor Watts, Tyrian and Hazel. Known associates of the group include Cinder's subordinates Emerald Sustrai and Mercury Black, the criminals Roman Torchwick and Neopolitan, as well as some elements of the White Fang under Adam Taurus. Enemies of the faction include Ozpin's Group as well as the Academies and Kingdoms.

History
Origins of Salem's Faction are still unclear, though what is known is at some point, Salem recruited members into the fold to assist in her plans. Hazel has also stated that the group has dealt with many "silver-eyed warriors" in the past.

Cinder Fall and her group's actions, including stealing the Fall Maiden's powers, recruiting Adam Taurus and the White Fang and destroying Beacon Academy, were all orders given and directed by Salem. Cinder's position as the new Fall Maiden is also said to be the "key" to Salem's plans.

Actions of the other members are not completely known, though Tyrian was given a similar assignment from Salem to hunt down the Spring Maiden, but has currently been reassigned by Salem to capture and retrieve Ruby Rose for defeating and scarring Cinder. Watts is assigned to take Cinder's place in a meeting with their informant in Mistral. Hazel is also to attend an arranged meeting from Adam Taurus with the White Fang's leader, Sienna Khan, to convince him to join them. Salem also reveals that Haven will be their next target following the destruction of Beacon.

Trivia

 * Watts, Tyrian, Cinder Fall and Hazel's first initials create WTCH when put together. It is possible that this is related to the meaning of Salem's name.
