Bone Wasteland was a desolate desert world that was filled with Bone-type Monsters and Monster Beasts.
However, Aeon observed one thing that there were almost no monsters in the place where he appeared.
The place that he returned to, after dealing with the Skeletal Gouls was the place where he first appeared in this world.
'It was as though this was a safe point for me in this Battle Play.'
Aeon decided to call the place where he appeared Safe Point and believed that it was to make sure that the Artifact User who entered this world would not be instantly killed by the world's monsters and monster beasts.
Thus, Aeon decided to make use of this place to rest for some time while waiting for the rewards from the Grimoire of Life and Death.
'I thought I would be invincible with my Combat Crystal Avatars; however, it is very costly to let them go all out.'
