Perhaps the next time you decide to venture into Lord Castigere's temple in attempt to slay one of his followers in there, you will have your gear fully protected.
In addition, you were not team stripped, my dear, it was just Dunccan that took your sack. Please see one or more of your city elders for instructions on how to protect your sack, backpack, pouches, and any other important items. You also may refer to the recent posts made by your city mates for advice on how to get over the mental anguish you may have suffered due to this loss.
Have a nice day.
Written by my hand on the 18th of Ilmarael, in the year 1160.
