The Primordial Beast of Sloth was readily wasting time and lazing about as all the mutated monsters around it have already charged towards the ones that dared to come to its territory. The Primordial Beast of Sloth did not even care about the beings that came into its territory as it already knew the future. The only problem is that the future is not as solid as the Primordial Beast of Sloth thinks.
Even for the Daemos, the literal demons that could manipulate time, the future is never set in stone. Various factors could change it such as the appearance of beings that do not have a predestined path in life like the blessed ones or players. The Primordial Beast of Sloth did not know that it took a glimpse of a future where players did not even bother to go against it.
