Cavir

Cavir is a planet populated by Feral zerg.

During the Great War, Daggoth used the planet as a birthing colony for his Tiamat Brood. After the death of their leader the zerg became feral and fought each other. During the Second Great War, Abathur discovered a small group of Lurkers among the survivors.

The Queen of Blades was able to control the group of lurkers, but coudn't morph more of them. Abathur informed a key sequence was missing, and that a Lurker den was required. One was found nearby and the group of lurkers was used to reach it and protect it from more feral zerg until Broodmother Kilysa arrived to recover its essence.
