Apart from the werewolf, human, and fairyland realms, other worlds have also prepared the best shelters to reduce the casualties of these creatures from the shadow realm. Unfortunately, their sanctuary was not as good as the three major realms.
As a result, there were still many victims resulting in many lurkers that evolved due to considerable consumption.
Even though the protective space of the four major realms was enormous, if they didn't immediately exterminate all the lurkers in the other realms, they wouldn't be able to withstand the attacks of the fourth, even fifth, waves.
The only way was to hope for Lord Cecilion, the Lord of the darkness, to release creatures of the dark realm to attack the lurkers around the world.
However, the Holy Priest who lived in the Enchanted Forest's interior temple received a distress call from other realms indicating that Lord Cecilion had yet to show his nose.
