So I'm interested in this RP and I was curious as to what the librarian does. If it's what I think it is, I might submit something.

The librarians job is to keep safe the tribes archive of knowledge. As a hobby I would assume the librarian would try to study the books, scrolls, and data scavengers bring in. The librarian would be the historian. The tribe would have an apartment just filled with books. 
Also he would be the tribes tactician since he would have extensive knowledge on maps, history, books stuff like that. 
Honestly if you don't like that it's positions meaning is open for negotiation
