The Astropath Transcendent is a rare individual, indeed. He is a psyker whose powers and very essence has been touched by the light of the God-Emperor himself and who is able to form a lifeline of communication across the limitless gulfs of space, his soul armoured against the gnawing taint of the warp beyond. Each year, uncounted millions of psykers are born across the vast breadth of the Imperium. Most are detected and interred until collected by on of the fearsome Black Ships of the Adeptus Astra Telepathica. These vessels travel the galaxy in great circuits, their stygian holds inexorably filling with nascent psykers with each stop they make. The fate of the vast majority of the psykers is to fuel the insatiable fires of the Astronomican so that the Imperium might be held together for another day. Of those allowed to live, a tiny fraction are judged strong enough to undergo tutorage and go on to serve the Imperium in a staggering array of capacities, from Inquisitor to Battle Psyker.
