For a moment, Atlas was unsure of what to do.
He did have an original plan that he could follow, but when he left the dormitory, he learned some crucial information.
Rather than being on an ordinary Tower floor as he expected, the dormitory was in an exclusive world. In other words, a hidden world.
'There are nine main worlds attached to the Tower. The nine of them are Neutral Zones. However, the Tower is also connected to an infinite number of worlds. It has become the very core of existence, thus, even that which exists outside of its influence still somehow falls under its umbrella.'
This world specifically was the property of the Society known as Dusk. It was home to several facilities, some that Atlas knew of and some that weren't even contained in his information.
Once he realized this, he got the urge to stay. After all, as long as there was any influence from the Tower, leaving a world was easy. Entering it again was a different story.
