===[[Librarian]]===
{{main|Librarian}}
Due to the [[Council of Nikaea]], the Librarius was dissolved among the legions, but as many can attest, this was not for long.

In most cases, a psyker was elevated to a more senior position to make use of their unnatural powers, but as time passed, it became clear that the powers of psykers were one of the only ways to defeat the foul warpspawn that the traitors summoned...or to summon them. Following the Heresy, Guilliman would formally reestablish the Librarius as a structure in the Chapters.

As with their successors, these Librarians have access to [[Force Weapons]] with which to channel their psychic powers. Psychic Hoods did exist in this era in order to help cancel out any harmful psychic influences, but they were not so common that they could be issued to any Librarian that wanted one.

====Caster of Runes====
Before they were called [[Rune Priest]]s, the Casters of Runes were the standing psychic force of the [[Space Wolves|VI Legion]]. Of course, they were deemed "exceptions" to the ban on Librarians due to claiming their powers were derived from shamanism and channeling the spirit of their homeworld of [[Fenris]]. Nobody bothered to call them out on this due to the fact that the Space Wolves were effectively the Emperor's attack dogs that got sicced on any naysayers.

Practically, aside from their limited choice in psychic powers (including some of their own), they were identical to Librarians.

====Esoterist====
Among the psykers of the legions, only a few dared to dive deep into the unknown fields of Warpcraft, but it proved to be incredibly effective, if in varying ways. While the loyalist legions had Esoterists who studied how to banish daemons outright, the traitor legions discovered ways with which they could summon the forces of Neverborn into reality with their own power.

Esoterists are a specialization that were originally introduced at the tail end of the first edition of the HH tabletop. They are identical to Librarians with two exceptions - one is access to Archaeotech Pistols, but the bigger one is their unique Anathemata psychic discipline (or the Sanctic/Malefic Daemonology in the original books), which normal Librarians don't get access to.

====[[Stormseer]]====
Similar to the VI Legion, the Stormseers of the [[White Scars|V Legion]] were also treated as special "exceptions" to the no-Librarians rule due to being shamans, though the Stormseers weren't so hypocritical as to reject the Librarius as a failed structure. These Stormseers would persist after the Heresy and effectively become the Librarius for the chapter.

Practically, aside from their limited choice in psychic powers (including some of their own), they were identical to Librarians.
