Although Gusttat and his associates had escaped previously, they were still in danger, because to flee they had to abandon their disguises, and the power of an abyssal is easily recognized, due to its aura of chaos and death.
Not even the vampires who are known for their bloody and deathly aura were as recognizable as the abysmals. Fortunately for them, the other 5 abysmals who attacked the kingdom of Vacilea attracted all the attention and they were able to escape.
Although the abysmals have a tendency to destroy everything, Gusttat and the abysmals who still followed him had evolved and learned to control these impulses, something that those who attacked the kingdom of Vacilea could not.
Gusttat knew that in Vacilea, as well as in all the countries of the continent, there were demigods who could cause them problems, that is why his plan was to take over the underworld of the continent, since this way he could make moves without exposing himself.
