Cataclysmic Wranaui civil war sparked by the discovery of numerous technological artifacts made by the Old Ones, including the Seed and several other forms like it. This led to the Tfeir’s heresy of the flesh. While Arm fought Arm for supremacy, the Wranaui also engaged in an ambitious expansionist campaign, colonizing numerous systems. Their internal conflict nearly destroyed their species, partly through conventional warfare, partly through the awakening of a Seeker, and partly through the inadvertent creation of Corrupted/nightmares. As a result of the Sundering, Wranaui civilization was shattered, and it took nearly three centuries to fully recover.
