Librarian

Every knight of Titan is born a psyker, yet even among such gifted brethren the Grey Knights Librarian stands apart, a mind honed to a razor's edge and schooled in the forbidden discipline of sanctic banishment. Where his brothers wield their powers as a soldier wields a blade, the Librarian commands the warp itself, weaving wards of pure force, hurling spears of silver fire, and tearing the daemon from realspace with a single focused thought. Such power is perilous beyond measure, for to reach so deeply into the empyrean is to invite its denizens to reach back. Only the iron purity of the Grey Knights makes this art survivable, and only their Librarians dare wield it to its fullest and most terrible extent. In war he serves as the beating psychic heart of a strike force, sensing the ebb of unclean energies, shattering enemy sorceries before they can form, and steadying the souls of his brethren against the whispering horrors that press upon them. When the Librarian raises his force stave and speaks the words of banishment, whole legions of the warp are unmade.
