Chief Librarian

From Lexicanum

The Chief Librarian is the strongest and most psychicly attuned Librarian of a Space Marine Chapter, who all other Librarians in the chapter bow to. He is master of the Librarium and is a living encyclopedia of knowledge due to his unrestricted access to the texts of old. He is also a greatly talented Psyker, stronger then even the Epistolary Librarians. Chief Librarians often lead forces or assist the Chapter Master in battle. Chief Librarians also spend a great deal of time training their lesser Codicier and Lexicanum brothers.

Notable Chief Librarians Include:

• Mephiston of the Blood Angels
• Tigurius of the Ultramarines
• Ezekiel of the Dark Angels
• Ahriman of the Thousand Sons
