Did you guys know you can bribe the guards so they don't attack you? o: All you have to do is give a few bars (which you'll have anyways from pickpocketting) to your company's director (you can check via your quest log for The Giant Dwarf). Make sure you don't thieve from your own company though
This is pretty nice since trapped guards reset every so often, I think?
If the northern guards are lured into the north-western room and the southern into the south-eastern room they won't reset untill the next game update. :>
