Prince Eslaw

Eslaw Ostrow was a prince of Vichin and firstborn son of Casmer III the Great. His father showed no attraction for warfare, but prudently strengthened Vichin by centralizing the state and forging a strong state exchequer. In 1364, he sponsored the Congress of Kurnow that attempted to promote peaceful cooperation between the Magnian countries. Early in his life, Eslaw angered his father by marrying a Valonian magnate daughter against Casmer's wishes and without his knowledge.
=== Exile ===
During the congress, Prince Eslaw attempted to thwart his father's negotiations with Corveaux, who he deemed unfit to treat with. Once the first delegation of Corvian diplomats arrived in the capital, led by a minor Corvian lord, Simonnet Delacour, he was arrested by the city guard and then beheaded in the Bloody Keep. Casmer III was forced exiled his son for this heinous act to quell the Corvian's anger and Eslaw could only watch from Valona as the Ostrow Dynasty ended and the Martels of Magiore ascended the Vichin throne. However, during the Vichin Civil War, which started in 1382, the Duchy of Volynia supported neither of the warring sides, but urged Eslaw to return and claim the throne. 
=== Death ===
Due to the ascension of King Florence II to the throne, it was not until the Battle of Dog's Field in 1407 that Eslaw would finally set foot in his father's lands. He led a force 15.000 men strong against an army twice their size. Eslaw was killed, the battle was quickly lost, and his 15-year-old son, Casmer, was dragged from the field wounded.
