Bertelm at the Allerian Stronghold wants you to bring him 12 Timber Worg Tails. The tails can come from either Timber Worgs or Timber Worg Alphas.
Have you come across the timber worgs in your travels? I've had the opportunity to observe them while mapping some of the northern reaches of the forest. I wouldn't recommend getting close to them unless you're prepared for combat.
They have no fear of us and won't hesitate to defend their territory.
It's fitting that such a creature would have a magnificent tail. I've been trying to collect enough of them to trim a new cloak, but the worgs have a habit of evading my snares. Will you help?
