Salem

Salem is the primary antagonist of RWBY. A very mysterious figure in Remnant and highly knowledgeable about the world and its forgotten history, she is the leader of a group of people with malicious plans. Her goals are to find the Maidens, take their powers, take the Relics from the Huntsman Academies and weaken humanity by snuffing out their hope. She is opposed by Ozpin, with whom she speaks directly in "Ruby Rose" and "End of the Beginning".

Salem is voiced by Jen Taylor. She was named Mysterious Narrator in the credits of "Black and White" and "Breach". In "Ruby Rose", the first episode of Volume 1, she serves as the narrator, giving the opening voice-over for the series. She is also the narrator of the first four RWBY: World of Remnant episodes. She makes her first on-screen appearance in the Volume 3 finale, "End of the Beginning".

Appearance
Salem's skin is a deathly pallor, covered with deep red and purple veins that run up her arms and face. The sclerae of her eyes are jet black and her irises glow red, even brighter when she is agitated. She has a black diamond-shaped marking in the center of her forehead.

She wears a very long black robe with red designs resembling eyes. She also wears a ring resembling an insect on her right index finger. She has white hair formed into a bun with six offshoots from which ornaments are suspended.

Personality
Salem is insidious, patiently moving to undermine and destroy her enemies with cold, deliberate resolve. She is also highly intellectual, with a healthy respect for her enemy, mankind, which she recognizes as possessing both resourcefulness and ingenuity. She also acknowledges humanity's capacity to draw strength from hope, but she uses this knowledge to subvert and destroy them. She is humble enough to recognize that there are limits to her abilities and that she can only do so much for her subordinates.

She is very confident and self-assured, secure in her knowledge that she can best whatever Ozpin sends to stop her and her goals. She also appears to be cruel or sadistic, for she seems to relish the prospect of watching Ozpin burn.

In contrast, Salem is also fair and collegial towards her allies, giving credit where credit is due and showing genuine appreciation to those who are loyal. In enforcing this atmosphere of fairness, she also discourages unnecessary malignance and cruelty amongst her associates. When Tyrian Callows returns after having failed to capture Ruby Rose, she merely tells him that he disappointed her and walks away. She is also seen tolerating her allies unruly behavior to some extent, such as Tyrian's manic tendencies and Watts' snide condescending attitude.

However, Salem is not above losing her temper, as she is particularly demanding when inquiring whether Cinder has truly killed Ozpin or not. She later became angry with Lionheart after he started to become less afraid of her and be more outspoken in her presence. This display of sheer dominance shows Salem's rather imperious and demanding personality.

Both Qrow and Raven describe her as someone who would make use of anybody to help further her goals, something Salem herself suggests when explaining her decisions to Cinder. Raven states that she would discard the people she uses if they become obsolete to her, which is later violently demonstrated when she kills Lionheart for trying to run from the Battle of Haven.

Salem is actively seeking out the Relics left behind by the brother gods. Her current goal is to acquire all four Relics as well as the power of the four Maidens, needed to unlock the chambers containing the Relics.

Powers and Abilities
Salem's true power is yet to be seen and very little is known of her abilities, however she is hinted to be extremely powerful.

Raven Branwen reveals that Salem is the Grimm's master. As such, she can command them to do her bidding and even create them from the pools of black liquid outside of her home. Salem has lived for thousands of years, during which she acquired extensive knowledge of the nature of Aura and Dust, as well as an understanding of human nature, society and history.

Salem is also very effective at getting others to follow her orders through fear. She controls Tyrian with statements of approval or disapproval and controls Lionheart and others by conveying their well-being is contingent on cooperation.

Qrow Branwen claims he has "seen the things she's made" and that "they are fear". She also possesses knowledge on how to steal the powers of Maidens, a feat of which was never accomplished before according to Ozpin's group.
