Salem's Inner Circle

Because of your efforts, Beacon has fallen. And Haven will be next.

Salem's Faction (unofficial) is Salem and the subordinates assisting her in her plans. Their objective is not clear, but it apparently involves causing the downfall of civilization across Remnant. They also appear to be hunting down and taking the powers of the four Maidens, though to what end is not known. The group is closely connected to the Grimm, as their headquarters is located near to a desolate spawning ground for the Creatures of Grimm.

Apart from Salem herself, known members include Cinder Fall, Doctor Arthur Watts, Tyrian Callows and Hazel Rainart. Known associates of the group include Cinder's own subordinates, as well as some elements of the White Fang under Adam Taurus. Haven Academy's headmaster, Professor Lionheart, serves as an informant in Mistral. Their opponents include Ozpin's Group as well as the Academies and the Kingdoms.

History
The origins of the group are not clear, though at some point prior to the start of the series, Cinder Fall and the other members were presumably brought into the fold by Salem to assist in her plans. Hazel, one of the members of the group, also states that they have successfully "dealt with" silver-eyed warriors in the past.

The activities of Cinder Fall and her group, including the recruitment of Adam Taurus and the White Fang, the theft of the Fall Maiden's powers and the destruction of Beacon Academy, were carried out under Salem's direction. Cinder's status as the Fall Maiden is described by Salem as being "key" to their further moves. Due to Cinder's new unspecified "weakness", Salem instead opts to keep Cinder close to her.

The actions of the other members are not known in detail. Tyrian has been on the hunt for the Spring Maiden for some time, though at a meeting following the fall of Beacon, he is reassigned to capture and retrieve Ruby Rose after she defeated Cinder. At the same meeting, Watts is assigned to carry out Cinder's role in meeting with Professor Lionheart in Mistral. Hazel is to attend a meeting arranged by Adam Taurus with the leader of the White Fang, Sienna Khan, in order to bring him to heel.

Following Beacon, Haven Academy appears to be their next target.

Members
Other associates of the group include Cinder Fall's underlings, Emerald Sustrai and Mercury Black, as well as Adam Taurus of the White Fang. They also have an informant in Mistral, who is revealed to be Professor Lionheart, the headmaster of of Haven Academy.

In a panel at RTX Sydney 2017, Miles referred to the team as Team WTCH (Witch).
