Stages of "Capture the Castle" quest
1. Meet Damien at Count de la Croix's mill after midnight.
Ducal guardsmen commanded by Captain Damien de la Tour were to aid Geralt in storming Dun Tynne - this was the duchess' wish and command. The briefing before the assault would be held at the mill where Dettlaff had recently dispatched Count de la Croix in cold blood.
Go to the mill and wait untill midnight.
2. Tell Damien when you're ready to storm the castle.
3. Search Dun Tynne for Syanna and Rhena.
Kill a few Dun Tynne Guards (47), move forward then kill two more guards.
4. Defeat Roderick and his men.
Defeat few more guards and then Roderick of Dun Tynne himself.
Wounded Roderick will tell you where Syanna is. You can help him or leave him alone.
5. Defeat the guards and reach Dun Tynne's keep.
Within Dun Tynne's walls, the witcher came upon Roderick. The old knight had erred many times in his life, yet never as gravely as he had when opening his castle to a group of bandits, a vandaguild. He had been persuaded to do so by none other than Syanna, Duchess Anny Henrietta's sister. The young woman had clearly captured the lord of Dun Tynne's affections, or perhaps merely aroused his passions. This achieved, she had quickly wrapped him round her finger. Interestingly, Roderick seemed to know Syanna well, yet he had heard nothing of her abduction. Having questioned the wounded knight as much as he wished, Geralt set off for the castle's keep, in a room of which he expected to find Anna Henrietta's dear sibling.
You can fight the guards but you can also just run to the terrace where Regis and Dettlaff will join you and help you to kill more enemies on your way to the keep.
In the keep you will meet Syanna also known as Rhena.
6. Quest completed.
Your decisions during the conversation do not matter at how this quest is going to end.
While storming Dun Tynne, Geralt was surprised to find he had two allies - Regis and Dettlaff. Naturally, the witcher assisted by two higher vampires plowed through the castle's defenders about like the Nilfgaardian conflagration had plowed through Cintra. At long last they reached the room where Geralt expected to find Syanna… And he was not disappointed. Yet it turned out Syanna was not just the young lady banished from court those many years ago. No, she was also Rhena, the missing, presumed-to-be-kidnapped young woman who was Dettlaff's beloved. The witcher and company learned she had controlled the Cintrian, bidding him to steal Sangreal wine as well as the ducal jewel. She had also sent Dettlaff the names of the intended victims. The vampire needed all his strength to quell his desire to tear her to shreds then and there. He seemed a shard of ice as he set a meeting time and place - Syanna was to appear at Tesham Mutna three days hence to explain herself. The witcher found himself between a rock and a hard place. One the one hand, a vampire consumed by fury demanded he deliver Syanna to him in three days' time. On the other hand, Anna Henrietta awaited, expecting Dettlaff's head on a silver platter.
