Tithenolf wants you to discover what is causing the Wood-trolls and Huorns of the Balewood to become so aggressive.
'The forest...is not itself, friend. When Barallas and I awoke from our sleep, we did so in darkness. And...we awoke into violence. Hoom. Such happenings are troubling, and I fear that Finglas cannot wake to aid us, for he had been becoming more and more tree-ish, so to speak, before our sleeping.
'The Wood-trolls harry us wherever our limbs carry us in this gloom and the Huorns... they are unruly without Finglas's tending. They may be beyond saving, though I do not wish to believe it so...'
'Hoom. The Wood-trolls must have been affected by Núrzum's passing. I can only wonder what wounds he inflicted upon them to make them far more hostile than they already had been to my kind.'
Tithenolf heaves a heavy sigh.
'Seek out the Wood-trolls, and for the good of this forest, please return them to the earth. However, I would ask that you examine their remains and perhaps then we can discover what has driven them to madness.'
Wood-trolls and Huorns can be found to the south, east, and west of Stonecliff.
Tithenolf wants you to defeat corrupted Wood-trolls and Huorns of the Balewood and examine their remains in hopes of understanding what has driven them to such aggression.
Tithenolf can be found in northern Balewood at Stonecliff near the path to the Limlight Gorge.
You should return to Tithenolf with news of the unnatural chill surrounding the Wood-trolls and Huorns of the Balewood.
