Primary hive cluster

A/the Primary Hive Cluster has been utilized by the zerg many times.

History
The hive cluster was on Char during the Great War. At the end of the Brood War, it was moved to Char Aleph.

During the Second Great War, the primary hive cluster was again on Char. In the Battle of Char, the combined Dominion/Raiders forces were able to create a diversion that allowed them to progress on the hive cluster and use a xel'naga device to de-infest the Queen of Blades.
