Wormholes. A link that connects two disparate points in spacetime.
Generically speaking, rifts were not difficult to see in the space which the Universal Government occupied. The reason for that, was the superimposition of the normal space over the dimension where the void space was. The two dimension occupied the same place, and yet not.
This superimposition caused the space to often warp and crack, and consequently, for rifts and portals to be created. If the individuals that ended up being dragged into these rifts were lucky, they would reappear within the boundaries of the territory of the universal government, otherwise, they would never return. The more time they spent into the void, the further they would reappear.
These rifts were usually temporary, and would repair thanks to the surrounding natural mana, or more specifically, space essence.. But wormholes were different.
