Galdor finally sent you. A band of orcs has infiltrated the walls and are held up in various places around
the city. We have been requested at the West Gate as they are in need of assistance, so you must do this.
The orcs have taken over three places:

1. Lesser Market
2. Gar Ainion
3. Palace courtyard

Go there and exterminate them before we attacked from with our own walls. Wait what? Maeglin betrayed us?!
This is ill news indeed. Head straight to Turgon in the throne room once you purge these locations of orcs.
He will most definitely want to hear this. I will spread the word to Tuor.
