There's a door in G'ezzard da's (the lich) library/study which has a level 12 lock. due to my lack of understanding of the role changing system my rogue is only at level 9 traps & locks presently which i presume is too low for him to be able to pick this lock. it may be a while before he gets to level 12. Can I use disarm or pry spells on this lock. Also in the Ironworks walkthrough I don't see any mention of what's behind this locked door.
is this an integral part of the plot?
