Adeptus Astronomica

The Black Ships bring thousands of psykers daily to the birthplace of man and many of those so tithed find themselves contributing to the vast psychic choir of the Astronomican. This steady beacon burns bright in the warp; it is the Emperor’s will manifest, shining from Holy Terra, and guides Navigators across the Imperium. The process of lending their psychic power to focus the beam quickly leaves the choristers as lifeless husks, but they give themselves willingly, for without the Astronomican the Imperium would cease to exist.
