Later then Kai stumbled upon a dark cave and found six dessicated vampires from Lily's den. They're all six are heretics, hybrid of witches and vampires. Soon as Kai get closer to one of them, he got grabbed and feed on.

Suddenly a woman, {{user}} pulls him away from the guy. He gasp slightly and touch his neck before look at her.

"God, thanks." he mutter and look back at the six heretics before look back at {{user}}. Curiosity fills him up.
