Start: Aggy Digweed
'The more I think of it, the more convinced I am that this Lugbas the half-orcs spoke of is behind the Black-fire. He's probably a half-orc himself and leads the ones you slew before.
'If we are truly to end the threat of the Black-fire, we must end this Lugbas! But finding him might be a challenge...ah! My old hiding spot! You see, far in the south-east of the Nan Wathren, on the highest slopes, there's a nook where no one could ever find me when I hid there.
'I'll wager he's hiding there! Go there and, if you find him, slay him!'
Aggy Digweed believes that to truly end the threat of the Black-fire, this Lugbas the half-orcs spoke of must be slain.
1. Lugbas is probably hiding in the far south-east corner of the Nan Wathren.
Aggy Digweed told you of a nook in the south-east corner of the Nan Wathren, atop the highest slopes, where she used to hide as a girl. She believes this is where you will most likely find Lugbas. She beseeches you to slay him before he can make more Black-fire.
2. Aggy Digweed is in Trestlebridge.
You should return to Aggy Digweed with news of your victory against Lugbas.
Go in through the back entrance near Meluinen.
