The moment that Nightwing awakened, he had a strange premonition of who he was and what his mission was. But he had no memory. All that he remembered was that he wanted revenge against the one who killed him in his previous life.
He knew that the path of being reborn as a mortal and to face life and death was the key.
He awakened and found his two servants. A Hydra and a Slime. Both were also confused and the slime had a peculiar personality.
Nightwing and the trio made careful consideration of what they needed and what weapons they had. The castle was slowly rebuilt as Nightwing enacted several ingenious means to gather more blood for his castle and used the underground regions where the goblins lived and cultivated which became a mini-town of its own.
