Changes

The Tyranids are an alien race from another galaxy whose sole purpose seems to be the consumption of bio-mass. They are divided into [[Hive FleetsFleet]] s that operate independently from one another. Each Hive Fleet has a "hive mind", controlled by the [[Norn Queen]], who generally resides in one of the Tyranid ships. The Norn Queen oversees all tactical operations and determines the path of evolution for the Tyranid species in that Hive Fleet.
