The zerg are able to infest almost any world they encounter, a testament to their amazing ability to adapt to the universe's most extreme environments. The planet Kaldir is one such environment. Its extreme cold and frequent flash freezes make this one of the most inhospitable worlds in the Koprulu sector... which is exactly what sparked the Queen of Blades’ interest in Kaldir. Hoping to make the Swarm stronger by evolving a way to deal with extreme cold, she sent a brood to infest Kaldir. However, the brood never reunited with the Swarm.
On Kaldir, Kerrigan’s objective is twofold: learn to adapt to the withering cold, and discover what happened to the lost brood. Before long, you will learn the brood's fate... and when you do, the cold of Kaldir will be the least of your worries.
