'The Orcs must have come through a breach in the northern cisterns. Some of the tunnels in the northern section have been closed off since I was a child as they fell into disrepair many, many years ago. You must find their entrance into the city and block it off. It may only temporarily halt their movements but having time on our side is most crucial.'

The mountain entrance to the Cisterns can be found at the northern end of the Cisterns.

You should seal off the mountain entrance to the Cisterns that the Orcs used to enter the city.
