Having Damien as a father, August had become more than used to being transported into separated realms.
His consciousness had been pulled into many spiritual realms to help him comprehend his law and strengthen his spiritual energy.
His body had been pulled into many hidden realms for different trials that gave him opportunities to adventure and train.
And illusions were something he'd become used to, as they were the best way to bring experiences into reality so he could experience them in a simulated environment.
His mind immediately recognized its spiritual state when he arrived in that place with rolling hills in the distance. Within the first second of being there, he already knew that his consciousness had been separated from his body.
With the preceding events painting an obvious picture, August could deduce that he was within a realm of the crown's creation.
He was only left to wonder what kind of trial he'd be facing here.
