The leader hurried to close the rift, which consisted of detonating a set of small special grenades in the small room.

On opposite sides of the rift, there were two tall pillar-like objects emitting pulsing light that shine on the dark rift. These two objects were spatial anchors... a kind of stabilizer that was used to maintain an open rift to prevent it from closed prematurely.

Like I said before, natural rifts were more stable and could remain open for a very long time without closing. Instead of worrying about keeping a natural rift open, one would worry instead about getting it too close.

On the other hand, an artificial rift was difficult to maintain, so stabilizers were needed to keep it open. Human research on space was very slow, and they hadn’t reached the point where they could open and close rifts in other worlds easily. The spatial anchors were a product of genius that had accidentally blossomed to fruition. It was with this anchor technology that the humans were confid
