Aragorn agrees that the threat of Umbar will not be ended until you face Balakhôr the Scourge on his flagship.
'I knew the flagship Night-jewel at once, for it dominates the harbour. That is where we will find Balakhôr the Scourge, and put an end to the threat of Umbar. Speak to me when you are ready to do this.'
Aragorn is at his camp in Lebennin, outside the city of Pelargir.
Aragorn is ready to put an end to Balakhôr the Scourge, and the threat of Umbar, once and for all.
Aragorn is outside the city of Pelargir.
You have driven Balakhôr away in shame, and the threat of Umbar is ended for now.
