Going back to the Walde family's lineage, its ancestors could be traced back to the ancient King of Blackwater who triggered the Rotten Moon Tide of the Undead 1,000 years ago. Be it the King and Rebel or the Eternal Gift rituals, they were all legacies secretly handed down by the Walde family over the years, so that they could restore the former glory of the Blackwater Kingdom one day.
It relied on the King and Rebel ritual to obtain the authority and strength of the ancient mythical God King, Oka, and then on the Eternal Gift to create an immortal army of the dead that didn't rest while being absolutely loyal. This was the plan Simon had proposed to Vincent in the Silverstream Mine more than 20 years ago to build the foundation of the new Blackwater Kingdom.
