Anywhere you see a tribe of enslaved Broken you will also find a traitor. A despicable being who sold his brothers for promises of power.
There is a hut at the top of the stairs in the center of the ruins. That's the turncoat's hut.
He's not there right now, so you will be able to sneak in if you're patient. Inside you will find a coffer with a key inside of it. That key unlocks the chains that keep the Dreghood elders prisoner. Bring it to me.
Beware, Arzeth the Merciless wanders nearby.
Progress
Did you obtain the key, <name>?
Completion
I thank you, <name>. My people will soon be free thanks to you.
Perhaps not all hope is lost for the Dreghood. I am one of four elders that guided this tribe before we were enslaved by the Illidari. I thought the others were dead, but I've slowly learned that at least two others are alive - chained down and powerless just as I am.
I've not yet been able to find Naladu and fear for the worst. There are more huts in the ruins upstairs; perhaps you could look for him. It would be a great boon for our tribe if all our elders were alive.
Completion
You've come to help my tribe, <race>? How unusual. There aren't many that care about the fate of the Broken in this land.
