Bring the voodoo feathers to Ashlam Valorfist.
Now we must combine the inert scourgestones and create a weapon to shatter the ranks of undead. This is no trivial task, [player]. Only the trolls of the sunken temple carry the kind of rare magic able to turn the evil of something against itself.
In the temple, the trolls are known as Gasher, Mijan, Zolo, Hukku, Zul'lor, and Loro. Do not feel remorse for their corrupt souls... they are not without evil.
