Glacius was an oceanic world that housed a Khalai Caste research facility, the site where the Purifier Revival Program was developed. It had served as a Protoss Empire research station since before the Great War, and the work conducted there on new Purifiers was kept secret from all but the highest ranking protoss officials. The facility was defended by orbital cannons and sentries, and it became a point of contention during the End War when the Daelaam and the Tal'darim clashed over the technology held within.

A secret research station#
Glacius had been a Protoss Empire research station since before the Great War. On the oceanic world stood a facility where the Khalai developed new Purifiers, a technology that was made secret to all but the highest ranking protoss officials. Additional research on advanced robotics and solarite was conducted within the facility, which was defended by orbital cannons and sentries. The site was known as the Glacius Facility. (StarCraft II: Legacy of the Void)
The End War#
During the End War, Hierarch Artanis moved to retrieve the prototype Purifiers and use them as a weapon against Amon and his forces. The Tal'darim under First Ascendant Alarak attacked the facility and began using their mothership's displacement beam to purify it. The Khalai scientists were evacuated, but the Daelaam were forced to race against the advancing displacement beam to retrieve the container holding the data on the new program. They succeeded, warping the container aboard the Spear of Adun before the rest of the facility was purified. (StarCraft II: Legacy of the Void)
