Surtur Brood

The Surtur Brood is one of the major Broods of the Zerg Swarm.

The millions-strong Surtur Brood, under the control of Cerebrate Kagg, is sent forth by the Zerg Overmind when the Jormungand Brood and the Garm Brood are unable to break enemy ranks alone. This brood is so destructive that it is kept in reserve unless absolutely necessary. It is kept in the central recesses of the Zerg fleet, and only used in the most extreme of circumstances. It has been known to eradicate fellow Zerg as well as enemies in its furious rampages.

History
The Surtur Brood has only been seen deployed once, immediately after the attacks on Chau Sara and Mar Sara. The Garm Brood, being severely reduced from these attacks, was unable to invade Antiga Prime alone, and the Surtur Brood was brought in as larger attack force to reinforce the Garm Brood. The brood was beset when the Norad II crashed right in the middle of its hive cluster, and its defenders furiously attacked the crash zone until troops under the comand of Jim Raynor and the Sons of Korhal broke through the Brood's defenses and saved the crew of the Norad II.
