Regis

A centuries-old higher vampire, scholar and barber-surgeon who gave up blood and became one of Geralt’s most loyal friends.

Emiel Regis Rohellec Terzieff-Godefroy, Regis for short, is a higher vampire who was already more than four hundred years old when he first met Geralt. He worked as a barber-surgeon in Dillingen, and knows a little about almost everything. In his youth he drank blood like the rest of his crowd, until a drunken flight ended with angry villagers beheading him, staking him and burying him. It took him fifty years to regenerate, and he came out of the ground determined never to drink again.

Regis in The Witcher 3: Blood and Wine
Everyone believed Regis was gone for good, but another vampire, Dettlaff, found his remains and slowly nursed him back to life with his own blood. When he hears that his friend is butchering knights in Toussaint, he comes to find out why. At the end of Blood Run he steps between Geralt and the Beast in an old warehouse and stops the fight. He has set up a crypt and alchemy lab at Mère-Lachaiselongue Cemetery, and in La Cage au Fou he brews the Resonance potion to track Dettlaff. The last ingredient is his own blood in a state of frenzy, so Geralt locks him in a cage at Tesham Mutna and slaughters monsters in front of him. Later he helps Geralt either reach Syanna in the Land of a Thousand Fables or face the Unseen Elder.

What happens to Regis?
Regis survives every ending, but his path depends on how the showdown at Tesham Mutna goes. If Geralt defeats Dettlaff, only another higher vampire can finish him, and Regis reluctantly kills his friend. Killing one of his own kind breaks old vampire law, so he has to leave Toussaint, though other vampires will ignore him if he keeps away. If Dettlaff kills Syanna and Geralt lets him walk away, Regis follows him to help him find his balance again. Our Witcher 3 endings guide covers how each outcome is reached.

In the earlier games
Regis is only mentioned in the first game: Dandelion recalls that Geralt once had a vampire friend, and the Queen of the Night names him as a former lover.

In the books
In Baptism of Fire, Geralt and Zoltan’s company stumble on Regis near an old elven cemetery and end up drinking his mandrake moonshine. He later rescues Geralt and Dandelion from a Nilfgaardian fort and joins the witcher’s company alongside Milva and Cahir on the hunt for Ciri. He keeps the group together through their long stay in Toussaint, until the assault on Stygga Castle in The Lady of the Lake, where Vilgefortz tears him apart and melts his remains.
