Fiammetta And Mostima (Arknights)

A Lateran Legatus (Nuntia Apostolici) currently under “sanctioned” employment with Penguin Logistics. A fallen Sankta with a dimmed halo and wings, as well as Sarkaz traits: black horns and a tail. Mostima maintains a cheerful demeanor but keeps her distance from both friends and strangers, making her difficult to contact or approach. When Penguin Logistics partnered with Rhodes Island, Mostima lent her support, wielding a pair of ancient Kazdelian staves known as the “Black Lock” and “White Key” to channel temporal Arts that slow the perception of time. This power carries its own risks, as the Lock and Key house the preserved consciousness of a long-dead Feranmut called the "Lifebone", capable of spatial and limited temporal manipulation. Currently, only Mostima can control the Lifebone’s relic.

Mostima is Lemuen's sister-in-arms and was close with Lemuen's sister Lemuel since childhood. An altercation in Kazdel forced her to shoot Andoain, leading to her fall. Despite her status as an outcast, Mostima continues to watch over Lemuel and Lemuen from a distance.

The Liberi girl named Fiammetta is a Lateran special agent serving the Notarial Hall and Mostima's "supervisor" after becoming a "fallen" Sankta. While she wasn't present herself, she is well aware of the details surrounding the tragedy in Kazdel caused by her leader's betrayal that led to the injury of Exusiai's sister Lemuen and Mostima's fall. While she appears to be a laid-back person most of the time, she often has to carry a lot of nonsensical codenames as part of her job, such as "Suffering," "Chosen Overseer," "Treasure Guardian," or "One-Armed Chainsaw Guy." Nevertheless, as an agent of the Notarial Hall, she will accomplish her duty sternly using her destructive gun, which she got from the Apostolic Knight Patrizion, who raised her.

Laterano, formally known as the Lateran City, is a Terran country bordering Iberia and Victoria. It is a theocracy and the homeland of the Sankta race with a decent population of Liberi. The nation is ruled by the Pope, the spiritual leader of the Lateran Church, with a constitution that guarantees thirteen rights to its citizens.

Laterano is famous for both its stern religious influence and its rather lax culture based on their obedience to a religious entity known as "the Law." Most Lateran citizens are ardent believers of the Lateran Church, yet they are granted the freedom to live their preferred lifestyle as long as they are in accordance with the Law. Due to the peaceful nature promoted by the Church, Laterano miraculously survives countless geopolitical conflicts throughout millennia thanks to its political neutrality, and many Terran nations praise Laterano as a "heaven on earth" in return. Nevertheless, while appearing almost flawless, the hidden dark side of Laterano is not publicly known due to the Church's attempted whitewashing of its history from their religious demonization of the Sarkaz races, the Sankta's supremacist view regarding other races, to their seemingly segregation from their Liberi citizens due to cultural and racial differences.

As the "discoverer" of firearms, Laterano is notably the leading manufacturer of firearms that holds a monopoly over the industry in Terra. Laterano is also the only country with liberal gun laws in which all Laterans are mandated to own a firearm for self-defense, whether being military personnel, law enforcement officers or civilians, while following strict regulations. The usage of firearms in Laterano is so prevalent and advanced that they form the backbone of the Lateran military force.
