Last update: 11 May 2016
Your current destination is the [High Overseer's Meeting Chamber] and it is located on the Overseer Campbell's first floor. The easiest way to get there is by choosing any door. It is worth noting, at this point, that you do not need to sneak, because, by default, there is nobody inside the chamber.
An alternative way to gain access is to walk inside using the abovementioned window sills. You could this way, reach the open windows of the chamber (the above screenshot). It is the best approach if you don't want to perform all of the optional actions already described, and prefer to focus on eliminating Campbell.
New Main Quest: Wait for Campbell and Curnow to enter the Meeting Chamber
New Main Quest: Kill High Overseer Campbell
New Optional Quest: Poison one or both of the glasses in the Meeting Chamber
Regardless of the chosen method of executing the plan, after entering the chamber you will learn that Campbell is talking to Curnow in the neighboring chamber. As a result, you will have several moments on your hands to consider how you actually want to play it. Ignore the new quest connected with killing Campbell, because you will also have the option to render him unconscious and excommunicate him. Possible variants are listed in the next subsection - Choose your way of eliminating the High Overseer Campbell.
