this is a question I thought up thinking about Librarian. in basic hes a Psyker that the space marines recruited and trained. now a normal marine is worth about, 5 guardsmen so it worth predicting that a Librarian worth about 5 normal Psyker. but, this is the point of the Thread, what would happen if a Chpater recruited a Null. whould they care? and if they did what then? would they train them to use there powers? How much strogger would they be? How would they learn who to do it? would they have to ask the assasains for help? what there role be in a chpater? What do the Purely codex chpater feel about this and how would the Inqusiton, for that matter the whole imperium fell about a chapter with blanks in it?
