Dark shrine

The dark shrine, is a protoss structure of Dark Templar origin in StarCraft II. It simply provides access to, and provides no upgrades or researches.

Development
The dark shrine was formerly known as the dark obelisk Its original conception was as a tower structure with defences superseeding 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.
