The Ruins were cataclysmic events which would sunder the Imperium between the forces of rebellion and corruption. The First Ruin is the smallest of the five, but its existence is necessary to enable the other four. Axioms long held in the hearts and minds of the Imperial citizen, both elite and common, would be shattered by the First Ruin. What will follow is our development of both the Ruin itself and the book that will bind its story within.
The First Ruin can be summed up in a single sentence: Araphel, Primarch of the First Legion, is tricked by deception and paranoia to order the complete annihilation of the Sixth Legion and its master, the Ash-Blooded.
One sentence, however, can not possibly contain the full account of disaster and death which will follow that one simple decision. Yet, it is this one decision that will begin anew a thousand tales even as it ends a thousand stories. What follows is but a fraction of the individuals and units who will act and react to the course of events which would eventually blossom into four more nightmares.
Come and see.
