Your companions have heard Orcs prowling through the ruins of Tharbad, which could mean trouble for the residents of Old Cardolan and Bree-land to the north.
'I can hear Orcs prowling among the ruins of the city, and if we do not post a watch, they may surprise us while we rest from the crossing. They have become an ever-growing threat in my own land, and the king has not the strength to oppose them; Rohan suffers.
'I will help your friend make sure this camp-site remains unoccupied by those who made it, if you will hunt the Orcs that prowl the city. We will stay here only long enough to dry our clothes and recover from the crossing, and the fewer Orcs between us and the northern road, the better.'
Orcs prowl the ruins of Tharbad and should be opposed by whatever hearty folk encounter them.
Egfrith suggested you deal with Orcs at the camp-fires to the west, on the other side of the broken bridge, enabling the three of you to plan your travel through the Orc-occupied city and beyond.
A man fights with Orcs to the west of the broken bridge in Tharbad. He could need your help!
The travelling clothes in which the man is dressed cannot hide the fact that he is a proven warrior. The bodies of the Orcs about his feet also do much to make that clear.
