Emiel Regis Rohellec Terzieff-Godefroy

From Witcher Wiki

Emiel Regis Rohellec Terzieff-Godefroy, or Regis, was a higher vampire and a friend of Geralt of Rivia. He died fighting at the witcher's side.

[edit] In The Witcher computer game

During Shani's party in Act II, Dandelion mentions that Geralt once had a vampire friend, Regis. To which Geralt derisively replies: "...and a dragon friend,, too?" which is quite funny because in short story "Granica możliwości" (The Border of Possibility), he did indeed make friends with a dragon. Zoltan also recounts that Regis could pull red-hot horseshoes directly from a fire with his bare hands. In Act III, the Queen of the Night mentions him as her past lover.
