According to His Majesty Roland's plan, the City Hall, the Security Bureau, the First Army, and the Witch Union were the four major organizations that constituted the administrative body of Graycastle. Except for the Security Bureau, for the other three organizations to take action, they would first have to get approval and support from the other departments.
This set of rules was initially made to utilize the full potential of the kingdom. When His Majesty was around, hardly anything would go wrong. However, the problems would usually arise whenever when His Majesty was absent from Neverwinter; it was difficult for the three parties to reach consensus on any given topic in a short time. Hence, when Wendy heard "demons are coming," she thought the best course of action would be to sound the alarm first and ensure the safety of Neverwinter before going through the process of holding a meeting.
