The group explored every inch of the empty area contained inside the stormy regions. Shafu ate all the giants on the path and used their energy to fuel the creation of perfect lairs inside its separate dimension.
Noah met and subdued many different magical beasts' packs. They were rare in that environment, but their previous domain was so vast that enough of them had survived the apocalypse and remained in those areas.
Shafu's separate dimension grew crowded as Noah kept promising salvation and food to the various packs on his way. His companions even limited themselves during eventual battles to make sure that he gathered enough specimens.
The high consumption of energy of the magical beasts inside Shafu forced the group to move quickly. The giants were a limited resource that would soon vanish, so Noah had to bring everyone back to the black landmass before the creatures inside the separate dimension started requiring the dragon's power.
