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.
