After a Umojan Protectorate expedition team to Jarban Minor was overrun, a blightbringer took over a cave system being mined by the Umojans for its unusual crystal formations and served as the central hub for secondary Umojan mining operations. During its time in the caverns, a prototype for experimental communications technology that could create holo decoys became embedded in its body.
When Agent Nova Terra and her Covert Ops Crew arrived on Jarban Minor to retrieve terrazine, Reigel noted that there may be technology in the cave system. Nova explored the caves, only to come face to face with the blightbringer. Nova slew the blightbringer and the infested terrans it spawned, and retrieved the experimental munitions embedded in its body.
A blightbringer serves as an optional boss battle during the "Night Terrors" mission of Nova Covert Ops. It has no automatic attack, but will create pools of acid that will damage Nova over time, as well as spawn eggs with infested terrans within. Grenades can take out clusters of eggs, but priority should be to destroy the large egg, as it will spawn a powerful aberration. The blightbringer also will burrow and move across the arena. Focusing the eggs while attacking when there is an opening should eventually whittle down its health.
- The blightbringer's model is the same as the one used for the infestor in the alpha period of Wings of Liberty.
- If Nova dies during the fight with the blightbringer or eradicators, she will drop a bundle that when picked up will say "+800 souls collected." This, and the name "blightbringer," are both possible references to the Dark Souls series.
