The emergence of the Dark Bible reminded everyone present that there had once been a force of darkness that was even greater than the Vampiric Empire.
The Covenant of Darkness was once a behemoth that had once ruled over half of Europe.
The covenant had been a monster that had once fought the church for ages.
The history of the covenant had even eclipsed that of the church.
There had even been rumors that the establishment of the church was a forced measure that resulted from humans having no other means of fighting the Covenant of Darkness that were going about business as they fancied.
The church grew in strength and influence from then on out. Eventually, the church was even able to overpower the covenant and ultimately crushing it, forcing their remnants to flee elsewhere.
