That blood elf witch, Cersei Dusksinger, has been cursing the Lost Ones, I just know it! I don't know why or how, but the results are tragic. Several of the Lost Ones have now been further corrupted - cursed with even more fel energies!
<class>, can you find it in you to take pity on these poor creatures? They should not have to live out the rest of their lives in such a horrible condition.
You'll find these cursed Lost Ones at the Fallow Sanctuary, east down the path.
