「Nonexistence」

Vacosian: Vacosians are a near-extinct natural born species of Warriors that made their home in the Ultimate Void, on planet Voidal. A majority of the race was exterminated by the God of Destruction Cerveze, however a handful managed to survive, rendering the race close to extinction. They play a cental role in the Cyverse metaseries, where it is revealed that Ruby and Blair are Vacosians who were sent to Remnant. The best way to describe a Vacosian is to think of them as Outer Gods in humanoid forms. Sometimes they have tails and horns too, but it depends from individual to individual.

Dracontine: Dracontines are a natural born species of highly adaptive warriors that were known among the earliest race to have draconic roots, if not, the earliest known trace that had direct ancestry from Primordial Dragons, before the subspecies division of draconic races had occurred. The Dracontines have been relatively under the radar for a good while after the Draconomachy, in which the total population of the Dracontines took a steep decline. However, at present time, the Dracontine race seem to sit very comfortably, with replenished populations, both in Universe 1 and 12, each residing in their own version of Planet Dracorex on both Universes.

Super Vacosian: Super Vacosian, occasionally known as Ascended Warrior, is a legendary transformation unique to the Vacosian race of both the first and 12th universes. It is the signature transformation of the Vacosians relocated to Remnant, all of whom have been able to achieve the transformation, but was famously first awakened by Ruby Rose during her battle with the evil Fall Maiden, Cinder Fall.

Explanation: It’s why some muses have multiple FCs. On that note, they’re not shapeshifters, but rather think of it like Super Saiyan, just changing hair & eye colors.

Universal Government: The Universal Government (UG) rules over Universe 12 with absolute authority, led by The Boss, UMI, followed by the 5 Celestial Dragons, the Fleet Admiral, and a strict military hierarchy. The UG governs countless planets and species, enforcing its control through a centralized system that regulates trade, taxes, and resources. Its military is vast, with Admirals and Vice-Admirals crushing rebellion and ensuring compliance across the universe. While the UG ensures peace and order, it does so at the cost of personal freedoms, ruthlessly suppressing dissent to maintain its grip on power throughout Universe 12.

God-Key: God Key (or Grand Key/Divine Key when translated) are ten tools/weapons created by Azathoth, that when brought together, would allow entrance into her domain and  ████, while  granting each of the 10 wielders ██████.

Blanchimont Kingdom: The Blanchimont Kingdom, ruled by King Blair, is a vast, continent-sized realm located on Remnant. The kingdom thrives on a balance of tradition and progress, with a strong emphasis on military strength, magical innovation, and a diverse economy. Major cities like Montclair (the capital), Valeford, and Ironvale are hubs of trade, magic, and industry, while the Wyvern Spine Mountains and other natural landmarks provide both resources and defense. Though the kingdom follows the voluntary worship of the Sun and Moon Gods, Blair herself is secular, focusing on personal strength and fairness in her rule. The kingdom’s military is a blend of knights, mages, and specialized forces, all reflecting Blair’s martial prowess and strategic brilliance.

Remnant Dragon Balls: The Remnant Dragon Balls are wish orbs created by the Guardian of Remnant, Kami and were later enhanced upon request by said creator after Ruby asked her for an upgrade. These balls are mainly used on Remnant and were the first type of Dragon Balls used in the metaseries. They have played a major role and impact in the series, being used by a variety of characters, including main protagonist Ruby.

Vesper was someone who carried herself with an easy confidence, rarely allowing pressure to show even when plans started falling apart. She was relaxed, playful and often treated dangerous situations with the same attitude she brought to an ordinary conversation. She enjoyed teasing and ragebaiting people, especially when she knew she had the upper hand, but she was never needlessly cruel. A lot of her smugness came from the fact of knowing she prepared more thoroughly than most people.

Behind this nonchalance, Vesper was extremely observant, to the point of noticing small changes in tone, body language and anything that looked slightly out of place. She often preferred gathering information before acting, though once she committed to something, she usually became stubborn enough to see it through even when walking away would have been smarter. She disliked being controlled or forced into soemone else' rules and had little to no respect for authority figures who relied on their position rather than competence.

Despite her reputation, Vesper wasn't driven by greed alone. She often choose her targets charefully and had a particular dislike for corrupt officials, wealthy criminals and people who believed themselves untouchable. She could be selfish, secretive and difficult to trust, but she's surprisingly loyal towards the people she cared aobut. Rather than openly admitting concern, she usually helped through actions, favors and conveniently stealing exactly what someone needed and giving it to them afterwards.

Backstory:

Vesper had once worked as a private investigator, taking whatever cases New Eridu Officials considered too inconvenient, minor or politically dangerous to touch. She became known for solving cases through patience, rather than force, quietly tracing financial records, Hollows and so forth until the truth had nowhere left to hide. Her career ended when one of her investigations uncovered evidence tying several influential figures to the illegal movement of Ether experimentations. Before she could expose them, the case was buried, her evidence disappeared and Vesper herself was framed for theft and obstruction.

Rather than clear her name through a system she no longer trusted, Vesper vanished. Months later, the Phantom Thief appeared for the first time, breaking into a private collection and stealing the records of Ether experimentation that were connected to her final case. She left behind a calling card, copies of the owner's criminal records and enough evidene to destroy his reputation by the morning. From then on, she targeted black-market collectors, corrupt officials and similar. Most of what she stole was sold to fund future operations, while more dangerous objects were hidden, destroyed or placed into more capable hands.

Over time, the Phantom Thief became one of New Eridu's more divisive Urban Legends. PubSec considered her a high-level crimonal, wealthy collectors cursed her name and ordinary people viewed her as a stylish nuisance. Vesper of course didn't care, instead treating every heist as part of the long investigation that ruined her former life. To this day, she's still searching for the people for erased her case, wanting revenge. Of course she no longer cared about proving her innocence, instead she wanted their secrets, their power and everything they had taken from others.

Trivia:

Vesper had the habit of pocketing small, worthless objects from crime scenes, such as buttons, coins or keycards and other shinies.

Despite looking rather refined, she had a surprisingly cheap taste in food, often celebrating successful heists with fast food.

Vesper is highly skilled at lockpicking, forgery, disguise work and reading body language, but her sleeping schedule is horrible.

Vesper can easily and perfectly remember blueprints, security layouts and more after only seeing them, but regularly forgets where she places everyday objects in her own home.

Her W-Engine, One Last Encore, is disguised as part of her cane, containing several functions the mun has yet to come up with.
