Platinum And Gravel (Arknights)

Even though Centaurea had been dreaming about becoming a knightess, reality drains such passion away. Upon graduation, the white-haired Pegasus worked as a lesser celebrity until she was somehow appointed by the previous Platinum of the Armorless Union to become its member. However, Centaurea was forced to take up such title and leadership after the death of the predecessor (as well as her mentor) due to his betrayal of the Union to save his loved one. Time has made the current Platinum both an emotionless assassin and a tired salarywoman, yet she still struggled to get rid of the unfair desicions on her life made by both the Kazimierzian corporate directors and the two Lazurites Monique and Roy.

After failing to eliminate the Nearl sisters during the 24th season of the Kazimierz Major, Centaurea concluded that enough is enough and decided to run away from the Union. Along her way, she accidentally bumped into the Doctor whom she tried to assassinate long ago. Nevertheless, Rhodes Island is willing to provide her shelter from the Union. As for Centaurea herself, she could finally let out a sigh of relief from her past burden.

Senomy is a Zalak chattel from Kazimierz who could not remember her background and bought into the service of the famous knight family Maypoles. Under the encouragement of her master Gekoski Maypole, she managed to rise into a Rank 4 campaign knightess in the Adeptus Sprawiedliwi Kazimierz under the callsign "Gravel". Even though she was freed later on, Gravel continues to serve the Adeptus as the bodyguard of the Grand Knight Ioleta Russell until she was attracted by the Doctor during Rhodes Island's stay at Kawalerielki. After protecting the Doctor from the nefarious Armorless Union, Senomy decides to join R.I. after the 24th Kazimierz Major as a covert ops and "wetworks" specialist.

Kazimierz, formally known as the United Knightly Territory of Kazimierz or the Kazimierz Alliance for short, is a Terran country bordering Columbia, Leithanien, Sami, Ursus, and Victoria that occupies much of the northern grasslands. It is a confederation of feudal chivalric orders with the Grand Knight serving as the head of state. The majority of Kazimierzians are of the Kuranta race, which is reflected on its national emblem resembling a knight piece.

Dubbed the "Land of the Knights and Commerce," Kazimierz has been famous for both its generational knightly tradition and the newly risen merchant class. The nation began as a confederation of fiefdoms serving the Elder house of the Pegasi until the usurp of the royal house by the Nightzmoras and the knights. Entering the modern era, a series of commercial incidents nourished its capitalists that modernized the nation, but the process came into conflict with the traditional knights who despised their greed and corruption. The economic imbalance also results in inequality in development between its rich mega-cities and its remote, sedentary villages.

The Kazimierz Armorless Union or simply Armorless Union is a Terran organization and the antagonistic faction in the Kazimierz Major trilogy (Maria Nearl, Pinus Sylvestris, and Near Light). It is a secret organization of assassins who are responsible for annihilating rogue Kazimierzian knights who could become a threat to the ruling bodies of Kazimierz via unconventional and more militarized tactics.

Although the Kazimierzian society has been much open as it modernizes, it still retains its old feudal traditions like chattel slavery and hierarchical structure. In the Infected's case, they are outwardly treated better than many other places in Terra; however, they are being discriminated against behind the scenes such as gladiatorial fights between Infected competitive knights in both open and underground tournaments and living in underground ghettos.
