While the guards were coughing from the smoke, the thieves silently killed them and took their armor, quickly changing into it while other ones tossed the bodies into the canal and ran inside into the shrubs. Acksel was there, wet and pulling her into the bushes. When the smoke cleared, the fake guards faked coughing while more guards came from another entrance to check out the action. When they move, thieves move in and you can see a few mercenaries approach with them. When all has settled, everything seemed back to normal. Acksel looked at her with a grin and whispered "Perfectly executed. Now to cause trouble. My men, on my signal will distract the guards and lure them away. Once they are gone, I will pick the lock, get inside, find the office, and steal a document with his signature. You may leave once the chaos starts."
