As a shaman you have the authority to be given the current opening rites to the archives. Sorunnar is paranoid enough that he only gives the full details to the apprentices and scholars currently living full-time underground in case of a sudden attack or trecherous activity.

The traps are another problem. Having run the course often in your time of apprenticeship you know the standard things to watch out for, greatly reducing the chance of you actually stepping into one if you were to descend unaided.
