Blood for Power (2021)

In the year 1260, while enjoying a rare peaceful day at the castle with his horse, Brick Rethel, the son of King Telko, receives a mission order from Cloud, a lifelong councilor of the castle. As this mission appears to stir up inevitable resentment and jealousy, Brick sets out to inform his younger brother Rioba of their father's wishes for the succession to the throne. Rioba, obsessed with his desire for reign and sovereignty, shows no hesitation to betray the values of honor and loyalty to the family that Brick, on the contrary, is ready to defend at the cost of his life.
