Since several of the continent's most powerful demigods had fought against the abysmals on the lost continent, it was not difficult for them to know that some abysmals had managed to escape.
Since the demigods would not mobilize unless it was a real emergency, they did not dedicate themselves to searching for them, they only notified the leaders of their respective countries and left the investigation task to them.
The plan was simple, the kings and queens of the continent would search for the abysmals and notify the demigods to eliminate them when they found them, however to date there was no sign of them.
Nobody expected that the abysmals would take refuge in the country with the least probability. Vacilea is not only an island separated from the mainland and somewhat isolated, but it is also the closest territory to the lost continent.
