Emerald Sustrai/History

Background
Emerald's history has yet to be fully uncovered. Only her association with Cinder Fall and Mercury Black is known. The rest remains in obscurity.

Touring Vale
Emerald appears lost and runs into the shop owner of the newly reopened From Dust Till Dawn, asking for directions to a certain address. As she rounds a corner, Mercury states that he knew she was lost and she offers to pay him to be quiet using money she stole from the shop owner. They arrive at a book store owned by a Faunus named Tukson.

Emerald begins to ask if he has certain books because of his shop's catchphrase, but she eventually asks him for a book he doesn't have. Things turn serious as Emerald reveals that she knows he is planning on running from the White Fang and that he knows why they are there. She asks him if he is planning to fight back and he shouts "Yes" before lunging at her. She ducks under him and Mercury kicks him as he is in the air.

Emerald and Mercury return to Roman Torchwick's base and he questions where they were all day, taking the address from Emerald's pocket without her noticing. Emerald and Mercury confirm that they were cleaning up Roman's mess. When Roman threatens them, Cinder appears and Emerald informs her that they killed Tukson, but Cinder seems more annoyed at their actions as it risks ruining her plan. Emerald then leaves with Cinder, but shows Roman that she managed to steal his lighter.

After the events involving Tukson, Emerald is seen with Mercury and Cinder inside Beacon Academy, who bumps into a running Ruby. The latter helps her up, but tells her to mind where she is going. She is then redirected with Mercury and Cinder by Ruby who points them in the direction of their building as transfer students.

Emerald is first seen observing a battle between Pyrrha Nikos and Team CRDL, and later Pyrrha against Mercury. Later that day, in a dorm room with Cinder and Mercury, they all begin to talk about Pyrrha's semblance, and how skilled she is, as also listening to Cinder's plan.

During the Beacon Dance, Emerald and Mercury enter the ballroom together. From here, the duo spends the evening keeping track of the attendees, watching to see if anyone could interfere with Cinder's infiltration of the Cross Continental Transmit Tower. At one point, Emerald warns Cinder that James Ironwood is leaving to check on the tower. However, Cinder is able to finish her task and return to the dance before he can see her. Emerald then lets Cinder take her place as Mercury's dance partner for the remainder of the evening.

During the events of Breach, Emerald assists Teams RWBY and JNPR in killing Grimm. She easily slays an Ursa using her weapons, and is seen after the battle, smiling with Ruby. She is later present as Adam Taurus appears by Cinder's side, explaining that the Faunus will listen to him, despite numerous losses in the caves during No Brakes.
