Librarian - Psychic Abilities: Masters of the esoteric arts, Librarians are warrior mystics who unleash the power of the Warp onto the 41st Millennium's battlefields. With crackling bolts of lightning and storms of telekinetic force, they smite the enemies of the Imperium, serving their Chapter as both peerless loremasters and masterful battle leaders.Space Marine Librarians are among the most potent of all of Mankind's psykers. Every one is a warrior of two worlds, mastering the arts of bolter and blade as well as being trained to fight foes upon the supernatural battlefield of the mind. A skilled Librarian can manipulate the energy of the Warp in extraordinary ways, and with spectacular effects. Compared to the sanctioned human psykers used by the other institutions of the Imperium, Space Marine Librarians can wield far more raw power in a considerably wider array of disciplines.Nevertheless, a few Chapters still recruit potential Librarians from the halls of the Scholastica Psykana, hoping to find gifted Initiates among the youngest and most brilliant of those pupils. If they manage to become Space Marines, the superhuman strength, discipline and longevity they acquire allows them to practise their art and bolster their mental defences over many more centuries than the relatively frail mind of a mere human could ever hope to manage. Though this power is sufficient to draw victory on a battlefield from the jaws of defeat, it does not come without significant risk.Every psyker's mind holds within it a miniscule link to the Warp, through which they access that metaphysical dimension to power their abilities. Each time a psychically sensitive individual uses the power of the Warp, they expose themselves to the malevolent entities that dwell there, their minds glowing in that realm like bright candles in a dark fog. With ruthless and often life-threatening training, psykers learn to obscure and defend themselves against these forces. Should their focus waver or their mental defences fall, however, a psyker's mind and body will be vulnerable to all manner of horrific fates. If a daemon gains access to realspace through the mind of a weak psyker, they could wreak untold havoc through the act of possession. Worse yet, they could even spell the doom of entire sectors by tearing a rift in the skein of reality and causing a daemonic incursion.Understandably then, to even become a Librarian, a Space Marine must be an exceptionally talented psyker and undergo years of gruelling training within the depths of their Chapter's fortress-monastery. This training continues throughout their lives, and Librarians are constantly testing their minds and bodies to reinforce the strength and breadth of their willpower. Therefore, just as a Chapter's Apothecaries test the genetic suitability of potential Space Marines, the existing Librarians are responsible for assessing all potential recruits to the Chapter for psychic ability.Any who show signs of psychic sensitivity must submit to painful and invasive mental bombardments before they are trusted to wield their talent in combat situations or are fully inducted into the ranks of a Chapter’s Librarius. Parallel to their instruction in the Librarius, initiates also undergo the same robust combat training as their brothers in the Battle Companies. Though the risks of using psykers in the armies of the Imperium are great, there are few individuals as potent on the field of battle. If, from a thousand potential candidates, even a single Librarian emerges, then it is a boon to the strength of the Chapter and its future.The warriors that win their place within a Space Marine Chapter's Librarius are feared across the galaxy by all who seek the Imperium's downfall. One need only witness one of these proud mystics as they stride through the maelstrom of battle, untouched by bullet or flame and hurling searing lightning bolts through the ranks of the Imperium's enemies, to see what they add to the already prodigious power of the Adeptus Astartes.Like a storm cloud that presses down upon the world, the psychic shadow of the Librarian causes allies and enemies alike to look up as he enters the fray. Light streams from his eyes and sparks dance around his head, hinting at the intense energy of the Warp coiled within the weapon that is his mind. The true mastery of a Librarian is evinced when he utters his incantations. In a booming voice that reaches warriors even through the roaring din of combat, his words and thoughts become lightning, flame, and swirling vortexes that ravage the air with their fury.Psychic powers are the physical manifestation of a Librarian's abilities, and mark him as distinct from any other individual within a Space Marine Chapter. Librarians of Codicier rank and above make use of their psychic abilities in combat. These include the ability to project their consciousness above the battlefield so that they can get a bird's-eye view of the combat in a ritual that commences with the recitation of the Litany of Sight Beyond Sight. Doing so opens a wound on their forehead exposing their psychic Third Eye, which allows them to view locations that would normally be obscured.Librarians can channel psychic energy (often through Force Weapons) to deal greater damage than a normal melee attack would allow. They can also read the minds of others, unless they are protected by psychic shields. Some Librarians are sensitive enough to determine the last thoughts of the dead before their souls were absorbed into the Immaterium and can even see the emotions that have strongly influenced a place. Librarians are capable of telepathic communication across vast distances and can also read the ever-shifting tides of the Warp, allowing them to sometimes demonstrate the capability of foreseeing probable futures through limited displays of precognition. Other psychic combat abilities commonly used by Librarians include the following powers:
