Louisa (30 November 1914 – 5 July 2004) was the second female and the final ruler of the Sunrosian Monarchy and and all of its constituent states. After her formal abdication in 1932, she adopted the name of Louisa Treniotis, and became internationally known as the Fortnight Queen following the publication of her eponymous first autobiography in 1946.
Born with congenital muteness that would leave her unable to speak for her entire life, Louisa was the only child of Adalbert XX and Sylviane of Gaullica. She was merely seven when she succeeded her father following his death on 25 December 1921, as his designated heir Prince Waldemar whearabouts' were unknown. Ascending to the throne in the midst of the Swetanian Revolution at a time by which most cities have already been lost to revolutionary forces, Louisa reigned only nominally as Empress for fifteen days before the proclamation of the Panswetanian Council Republic brought an end to the monarchy. She fled the country with her mother and entourage, first to neighbouring Werania and then to Caldia.
