Genestealers had been known for many years before the Tyranid hive fleets appeared, and it was some time before it was realised that they were part of the same genetically mutable race. Genestealers appear to be a form of scout. Operating on the edge of the Tyranid feeding grounds, they absorb the DNA of sentient species and create small hybrid communities. These hybrid communities radiate a psychic message that draws the hive fleets towards the worlds they have infiltrated. When the Tyranids arrive the whole world is stripped bare. Even its Genestealer scouts and their Hybrids are absorbed back into the hive fleets. |
