A refinery on Altara, operated by Project Shadow Blade, was detonated in order to cover evidence and lure ghost agents to the location. The bloom attracted the zerg. Nova Terra and Nova Squadron arrived, eventually defeating the zerg.
The terrazine refinery was made in a mad rush to get unique building artwork created for Ghost of a Chance. A quick solution was reusing about 60% of the building for another unique building, the mineral storage depot. A slip-up occurred in its design however, as vespene barrels can be seen rather than terrazine ones.
