Cain, as the ancestor of vampires in the Western World, was the very first vampire in existence.
He created the second-generation vampires, from whom the twelve branches were born. It was these twelve branches that established the twelve great vampire families of today's vampire world.
They governed the entire Western Dark World, standing on equal footing with the Holy See!
However, within the vampire families, there was also factional strife. The Lord of Mystery and the Lord of Blood Feast each controlled six branches of the vampire families.
The reason Maria and Connington had come here was by the command of the Lord of Mystery.
Previously, a branch of the McKinley Vampires under the Lord of Mystery had suffered greatly: not only had their clan leader, Wickliffe Allen, died in Yan Country, but his son Milos also met his demise here.
