I´ve always been a fan of stealthy characters who mess with their opponent´s minds, such as Zhalia Moon from Huntik: Secrets and Seekers. Ok, she doesn´t really mess up other people´s minds as often as Emerald, but Zhalia is very skilled in identity concealment, whether by magical means or by using her disguise kit and emulating different accents.But that´s not why I looked for fanart of her. Ok, I also wanted to see fanart of her, but there is another reason; I have a theory. A RWBY Theory.Anyway, here it is: Emerald is going to be the next Spring Maiden. But wait, there´s proof:1. The former Fall Maiden, Amber, was named after amber, fossilized tree resin of usually yellow or orange color, which posesses a crstaline (a.k.a. gem-like) structure. Emerald is named after emeralds, gemstones usually found in a green color.1.1. Both colors these characters are named after correspond with the color of a Maiden in the WoR episode The Four Maidens, with Fall being orange and Spring being green.2. Another proof for this theory is Emerald´s last name, Sustrai.2.1. When capitalized, "Sustrai" means "thief" in Basque.2.1.1. Emerald is a thief, so her last name references her profession.2.2. When not capitalized, "sustrai" means "undercurrent" or "roots".2.2.1. An undercurrent is an underlying influence not usually expressed openly or noticed, which references Emerald´s Semblance.2.2.2. Roots usually grow during spring. This translation of her last name is the only one that does not describe her character, while at the same time being the only one to follow the Color Naming Rule.3. Finally, her personality and backstory, as well as possible motivations and, most importantly, way to cheat her way into the position of the next Spring Maiden:3.1. Emerald always had to fight for everything, and there may be nothing she wants more than being able to ensure her own survival.3.1.1. Alternatively, when she witnessed the power of the Fall Maiden, she might have began thinking of gaining such a power for herself.3.2. She has been shown to be incredibly focused on Cinder, almost to the point of being dependant on what Cinder thinks of her.3.2.1. Now that Cinder is the Fall Maiden, Emerald might fear that she drops her as soon as she gets her voice back, which could lead to Emerald seeking the powers of another Maiden to keep up with Cinder.3.3. Emerald´s Semblance allows her to mess with people´s perception, which she could use to have the current Spring Maiden only see and hear her (Emerald-shaped trees, rocks, people, weapons, ect.) to ensure that the Spring Maiden thinks of Emerald when dying.
