Relative stability has kept the PU-5 system in a state of festering peace for over a millennia. The hive cities of Nidor and Laskar Prime have grown over centuries, spiraling towards the sky and tunneling into the bedrock of the planet, all due to meticulous bureaucracy and fervent, if not unrestrained, harvesting of the natural resources of their respective planets. For most of the inhabitants of the system, the drudging life in these hives is all they've ever known. Others eke out a living on the fringes of civilization and attempt to impose the guidance of the Imperium onto the wilderness and ruins.
While a millennia is long in human memory, it is but a sliver in the greater history of the system. Ruins lie buried or jut from outcroppings, old Imperial defenses lie overrun with decay and neglect. Settlements rise and fall, forgotten and lost beyond the strongholds the Imperium is able to maintain.

On the ever shifting Yarnsaxa, it barely registered. But then it spread. Soon, every planet in the system was giving unusual signals. Vox communication was disrupted, electrical signals delayed, wind and water patterns disrupted. Tech priests could discern nothing from the randomness, but one thing was clear: whatever the message was, it had reached beyond the system. It had been heard.Â

Imperial forces were unable to connect with the officials of either Nidor or Laskar Prime, leaving them on the frontiers of the Imperial planets. And it seems the Imperium were not the only ones who detected the signal...
