I am pretty sure under the apocalypse rules there was a squad called Librarium.
Using the Lexicanim, Codicier and Epistolary in a single squad.
I just stumbled on my lexicanum attempt a while back and wondered if it could be used in the squad with the other librarians.
From what I remember it was a squad of 6.....
I am yet to find the intel again... :P
Also I am thinking of doing a smoothing 1 on the lexicanum mesh.
