The following section contains information from a previous version of StarCraft II: Heart of the Swarm which is no longer valid.

A psionic vortex was a vortex of dark energy that could be created by hybrid dominators. If three of them merged, a planet could be destroyed by it being pulled into an event horizon.[1]


The vortex was a plot point in a previous version of the Heart of the Swarm mission "Hand of Darkness." If the vortex was created the player failed the mission.[1]
