Use the Bundle of Vrykul Artifacts at the ransacked burial mounds of Shield Hill to return the Frozen Heart of Isuldof, the Shield of the Aesirites, the Staff of Storm's Fury and the Ancient Armor of the Kvaldir.
Return to Orfus of Kamagua at the Ancient Lift should you succeed.
Within this satchel are the artifacts that you recovered. Locate the burial mounds of Shield Hill, far to the southeast, where the items were originally stolen from and return the artifacts. It is my hope that this gesture will quell the spirits that now haunt our hunting grounds.
