Journal entry[]

The Beast's and Geralt's clash had been violent albeit brief. Now With it done, Geralt could have a chat with his long lost friend Regis. A higher vampire, Regis revealed that the creature terrorizing Beauclair was none other than his dear friend Dettlaff. Geralt now understood he was pursuing a truly dangerous foe – a higher vampire, one of Regis' ilk. Then the witcher and the vampire heard a clamor. A posse was drawing near. So Geralt and Regis cut their conversation short. Preferring not to draw any attention, the vampire disappeared, but not before inviting the witcher to pay him a visit at temporary quarters he'd established at the local cemetery (you had better believe it!), Mère-Lachaiselongue.
Geralt paid Regis a visit at his cemetery hideout. After a long debate, the two old friends concluded their first order of business was to find Dettlaff. Regis was to prepare a concoction to aid them in this endeavor. Called Resonance, said brew required an array of ingredients, many of them hard to find. One such component was the saliva, or salivary glands, of a spotted wight, a species thought to be long extinct. Yet it seemed that one specimen remained alive, having made its lair near Beauclair. Geralt set out to find it.
If Geralt kills the spotted wight:
Geralt found the spotted wight at an old, abandoned estate. The witcher slew the monster and, its salivary glands in hand, made for the cemetery.
If Geralt lifts the curse from the spotted wight (or tries to, but fails):
Geralt found the spotted wight at an old, abandoned estate. The witcher chose not to fight it, opting instead to hide in a wardrobe and await his chance, though how it would come, he could only guess. Once the wight had come and gone, Geralt collected its saliva, which the monster had added to the brew it was making in a large cauldron.
If Geralt lifts the curse from the spotted wight:
Intrigued, Geralt set off in pursuit of the fleeing wight. To the witcher's surprise, the creature proved to be a woman who had been cursed centuries ago. Geralt set about lifting the curse that held her, and through his efforts the wight transformed back into someone of yore named Marlene.
Once Regis received the penultimate ingredient required to brew Resonance, he said the time had come to tackle the most difficult challenge. For apart from all else, Resonance had to include the blood of a higher vampire. At first, Geralt saw this as no challenge at all, as standing before him was a representative of said species. Yet Regis revealed that the blood he needed had to have a specific chemical composition. His blood would change only under conditions of great suffering. Regis offered to endure this without hesitation.
It proved quite the ordeal for Regis, a sacrifice one might say. But they obtained the last ingredient required for Resonance, and the vampire could prepare the concoction. Geralt drank a dose, and visions ensued. He saw Dettlaff, where he had recently been, what he had done. It was enough for Geralt to know he now needed to find a local bootblack. He hoped the boy would help him locate his foe.
