In the days before the unification between the Nerazim and Khalai, the dark shrine stood as a monument to the independence of Nerazim society. After the unification under the Daelaam, the structure became a training ground of dark templar.
Tal'darimblood hunters utilize a similar dark shrine as a meeting place, though the nature of their meetings are shrouded in mystery. The Ihan-rii dark shrines vent superheated fumes from its top, while its animated stone exterior is near-freezing.
Shrouds an enemy ground unit or structure in void energy, preventing it from moving, attacking, being damaged, using abilities, or detecting. Can be set to autocast, in which case the unit will only seal enemy detectors.
The dark shrine was formerly known as the dark obelisk. Its original conception was as a tower structure with defenses superseding that of the planetary fortress. It was later repurposed as a detection tower since design was testing the game with all the detection removed from the normal towers. Then it was cut from the game for a short time until the need for a Dark Templar building was required.
↑The Obelisk is the new name for the Dark Pylon, and the Dark Shrine is the new name for the Dark Obelisk. The Obelisk still has the probe buff, but now also acts as a shield generator, and still has Argus link to transfer energy as well. The cloak ability has been removed from the Obelisk. The Dark Shrine remains the same in function, allowing the production of Dark Templars. Karune. 2009-06-11. OBELISK question. Battle.net StarCraft II General Discussion Forum. Accessed 2009-06-11.
