At this point, our chief objective is to contain the orcs here in the Tower District and to prevent them from spreading further. We have people guarding the gates and manning the walls to ensure that the Many-Arrows can't move into any other districts in force.
Every so often, however, the orcs attempt to undermine or otherwise destroy the district walls. There have been reports of just such activity on the wall to the southwest. Go there and inspect it for signs of damage, then return here so I can assess whether an engineering crew will need to be sent.
