[Councilors]
Nothing too serious. Some vampires chose to not live within the laws of Preya. They were led by a single Alpha. It took us a few months to confirm that there was something beyond isolated coincidence. Once the Alpha was identified, some data mining was done to confirm bases of operations, and they were raided the next night. Events went rather rapidly from suspicions to case closed. It is in the reports.
I would not bother you with unconfirmed rumors. In the final stage all information was closely held to prevent leaks. It was a tactical decision.
