Elder Torntusk at Jintha'alor wants you to kill Hitah'ya the Keeper to get the Shackle Key to his bindings. Return to Elder Torntusk when you have recovered the key.
The key to my bindings is held by Hitah'ya the Keeper. She is in the nearby cave. Be careful, <class>, for she is guarded well.
Kill her and bring the key back to loosen my shackles. Only then will I be free to return home.
