- Talk to Nilwen under her shack, just north of Geirmund's Hall Wayshrine.
- Kill specific enemies chosen by Nilwen, or talk to Constable Gerrunn in Ivarstead to report her for squatting.
The questgiver, Nilwen, can be found in a shack in Ivarstead, near the Geirmund's Hall Wayshrine. When spoken to, she says that a "terrifying beast" named Lockjaw is nearby and requests that the Vestige kills it. Go to the location she specified and kill Lockjaw, then return to Nilwen. She will then tell you that there is more to be done and that more beasts are still in Ivarstead.
Nilwen then assigns you to kill another beast named Greatclaw in a different location. Once there, a bird, who is in fact Greatclaw, may be found next to a dead body, but will fly away when approached. Then return to Nilwen, who will commend the Vestige's actions and give them a third task.
Your final objective is to eliminate a goblin named Cracktooth, near Ragged Hills Dolmen. However, Cracktooth is not a goblin, but in fact a giant. Kill the giant and return to Nilwen, who will reward you for completing the quest.
