Lumielle Palettia

Having completed a spirit covenant, she is actually a human-turned-spirit close to a thousand years old and an ancestor of the royal family. Born to the first king of Palettia, she also entered a covenant to "support him and the country." She later killed her father for the "greater good of the nation," became queen, and eventually decided to abdicate, abandon her family, and go into isolation, believing it was for the best on account of her immortality.
