Max killed a Nocturnal Wild Vampire. This left him with a reigning question in his mind: could a Vampire Slave be killed?
'No, no. Vampire Slaves are somewhat undeads. We are somewhat undeads...'
Vampire Slaves were "somewhat" undeads and not "really" undeads because in this mortal life, nothing was not bound to the fate of dying. Definitely, the only one that was not bound to such a natural fate must be the everlasting entity who created death itself and also created life.
Even the so-called undeads could die.
How true!
It was a general knowledge that no one has ever killed a Vampire Slave; a reason as for why the theory of their possibility to die was always sounding more than a joke; a reason for why Max could not believe that he really killed a Vampire Slave right here with his hands in this abandoned restaurant.
