Take the Winterfall Ritual Totem inside Timbermaw Hold and see if one of the furbolgs there will find a use for the item. The Timbermaw will not speak with you unless you are of Neutral reputation or greater with them.
You have found one of the Winterfall furbolg's ritual totems. The totem itself is of non-descript construction, but it seems to emanate an almost tangible sense of dread and despair. If many of the Winterfall furbolgs do indeed carry these, it certainly would go a long way in explaining their current condition.
One of the furbolgs inside Timbermaw Hold may have a use for such an item... that is, if you've earned their trust enough for them to speak with you.
This thing... it is in the shape of a Winterfall Ritual Totem, but it has been twisted by forces I cannot begin to comprehend. Whatever taint that has set the Winterfall against us is surely present in this object.
Divine wisdom has brought both this and you to us, <name>. We will study this object intently; perhaps one day, the Winterfall will rage against us no longer.
Thank you, friend - please accept these offerings in exchange for your benevolence.
