In 779.M41 a starship bearing the Lilium of Charadon's markings drifted into the Ormasim System. Three Deathwatch Battle-Brothers, veterans of the Kaggeran Pogrom, boarded the derelict to investigate. No sooner had they boarded than the ship's Warp engines surged to life, carrying the Lilium into the Empyrean.
The mysterious return and disappearance of the Lilium coincides with an opening of the Omega Vault. The leaden doors swung wide revealing a single drop of blood hanging in a suspensor-field.
