The slightest change in the frequency of the portal would significantly destabilize it. Under the most severe circumstances, the ships that were inside the warp space would even get trapped.
An intense light gleamed at the center of the portal, sending waves of silvery, mercury-like ripples outward. A strong force suddenly took hold of the space-time continuum and shook it violently while a hyperspace storm was gathering inside the portal.

The shockwave engulfed the space hives as the desert storm would to ants.
