Coldain sappers have allowed the Kromzek to capture a few kegs of coldain spirits. I have agreed to infiltrate Iceshard Keep to poison the Kromzeks' ale barrels and move the keg of coldain spirits to a more volatile location. I need to avoid the Kromzek officers until my sabotage is complete. I understand that if I kill an unauthorized Kromzek or am seen at all, my reward may suffer.
