Inner Space, Layer, Boundary, Outer Space

The outer space and inner space acted as two separate entities.

Why was it considered so despite both being 'connected?

Because there was a large gap between these two spaces that didn't belong to either of them.

It was called by different names. The popular term among humans was 'Boundary'.

Boundary space had a single defining characteristic—it pushed.

Whenever anything entered the boundary space, it would push the thing to outer space.

So, when a space awakener wants to teleport, they'd use their space power and enter this boundary.

The stronger the awakener, the farther they can go inside the boundary: away from the outer space and towards the inner space.

The weakest ones, level 1s could only reach the boundary space just bordering the outer space.

The stronger ones would be closer and closer to Inner Space.
