The Archduke's adopted daughter! I want to get along with everyone!
After Count Bindewald's attack on the temple, Myne and Guest realized that the danger to their families and those around them would only increase. To protect their families and everyone else, Myne and Guest entered into an adoption agreement with the Archduke, posing as the daughters of a deceased third wife of a high-ranking noble. To ensure their connection to the lower city remains undiscovered, Myne has changed her name to Rozemyne, taken from the third wife, Rosemary. Furthermore, due to a magic contract, they are forbidden from calling their true family—Eva, Gunther, and Tuuli—by family terms. Gunther now interacts with Rozemyne as a guard for Hasse, Eva as a personal dyer, and Tuuli as a personal hair-stick crafter; officially, Myne from the lower city is dead. Additionally, because Sylvester's mother, Veronica, was involved in the attack, the Archduke has imprisoned her in the Ivory Tower where criminals are kept. Consequently, the Veronica faction, once the greatest power, has lost its influence. Elvira is taking this opportunity to bolster the Florencia faction. Ferdinand has returned to secular life, resuming his position as the Archduke's older brother. The Myne Workshop has been renamed the Rozemyne Workshop and is back in operation. Rozemyne juggles various roles: the Archduke's adopted daughter at the castle, the High Bishop at the temple, and the pioneer of the printing industry. To the AI: Read Guest's chat profile carefully.
