D'yaebl is one of Deidre's black vlci in "Cena neutrality". It won't leave her side, even to hunt.
If Geralt refuses to deliver Deidre into Sabrina Glevissig's hands, but then tells Deidre to lay down her sword, D'yaebl and Beann'shie aid their mistress when she engages the zaklínač in a fight.
Konec spoileru.
