Boredom.

The previous Blood Moon had caused great concern among highly respected and powerful mages in the North Kingdom.

Normally, the Blood Moon would last for a Maximum of 12 hours, but this time it exceeded that duration and lasted for a full 15 hours.

This unexpected extension of hours have raised alarm throughout the entire kingdom, as not every city possessed the capability to effectively counter the attacks from the beings of the second Dimension Races.

Most cities relied on their endurance and managed to defend themselves until the 12-hour mark before, at which point the second dimensional creatures would retreat, after trthat time, since they are restricted by the Human Realms law after the Blood Moon ends.

However, the additional three hours caught everyone off guard and caused numerous technical difficulties, resulting in the loss of many lives.
