Air Elementals words reminded him of something.
The difference between two-dimensional objects and three-dimensional objects.
If you drew two squares on a paper, you wouldn't be able to tell which square was nearer to you and which was farther away.
It was because the concept of 'depth' didn't exist in 2D.
But if you placed two 'cubes' in front of you, you could instantly tell which one was closer and which one was farther.
'Even if you can't notice the extra dimensions, they still exists.'
'How about we teach you a method to access them?'
"What will that do?"
'You will be able to enter them. Think of how useful it can be!'
'Other people from your species are incapable of seeing things beyond the fourth and a half dimension.'
'If you can access higher dimensions, to others, it will look like you disapper everytime you move!'
That sounded too good to be true.
