The Battle of Riovanes Castle is a battle in Final Fantasy Tactics between the Knights Templar and Knights of Riovanes that takes place in Riovanes Castle during the War of the Lions, though the two are not directly related. The battle takes place in the aftermath of the Knight Templar raid on Orbonne Monastery, in which they attempted to recover the Virgo Zodiac Stone and the Scriptures of Germonique. While they succeed in claiming the stone, the Scriptures fall into the hands of Ramza Beoulve, and Ramza's sister, Alma Beoulve, is captured and brought to the area around Riovanes Castle.
