Battle of Riovanes Castle

The conflict begins with the Grand Duke Barrington capturing Isilud Tengille while the Knight Templar is carrying the captured Alma Beoulve through the Duke's territory. The plan was, to use Isilud and the Zodiac Stones he carried as leverage to bring the Knights Templar - whom Barrington considered the greatest power in Ivalice - under his control. However, when Folmarv Tengille and his fellow Lucavi, Wiegraf Folles comes to negotiate at Riovanes Castle, the leader of the Knights Templar is not willing to compromise even for his son. Instead, Forlmav transforms into Hashmal, and along with Weigraf they slaughter the castle guards.

Battle
Meanwhile, Ramza Beoulve and his party, along with Rapha Galthena head to Riovanes to take Alma back when they are confronted by the Gaurds lead by Marach Galthena. After a battle outside at the Castle Gates, Rapha and Marach both teleport away to fight a battle between siblings.

Inside the caste, Ramza goes solo against Wiegraf in battle. Despite Weigraf's powers as a Holy Knight he is still defeated Wiegraf transforms into Belias the Gigas, and summoning several Archaeodaemons to aid him. Ramza brings his own forces to his aid, and the two sides battle. In the end, Belias is defeated. The party now has possession of the Aries Stone.

Alma listens to the chaos outside her prison cell with fear. A fatally wounded Riovannes guard enters her room for safety, only to sucum to his wounds after warning her to flee for her life. Trying to escape the madness, Alma makes her way to Barrington's chambers, where she finds Isilud fatally wounded - murdered by his own father for his weakness. Folmarv enters, and with the Virgo Stone is able to find that Alma is in fact the perfect host for Ultima. With her in his possession, Folmarv leaves Riovannes to continue the Lucavi Plot.

Rama and his party proceed to the roof of the castle where Barrington stands alone against the enemy. Rapha faces off against Duke Barrington, where he admits to raping her. Marach hears this and decides to side with Rapha, blocking a bullet for her and himself becoming fatally wounded. Then the Marquis Messam Elmdore shows up with Celia and Lettie enter, revealing themselves to be Lucavi in league with Forlmarv. They kill the Grand Duke by throwing him off the roof. Ramza and his party fight the three demons, but they flee.

Marach lies badly wounded, and as his life slips away his sister Rapha stand over him with a Zodiac Stone in hand. A voice tells her to use the stone to save him. Ramza, remembering how Weigraf was taken by the Lucavi, warns her against it, but Rapha listens to the voice. Her brother is resurrected by the light. Both join Ramza's party afterwards.
