Salem is the primary antagonist of Project Yellow. 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.

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. However, Salem is not above losing her temper.
