The Tale of the Muspah

Walkthrough
To start the quest talk to Erjolf who can be found on the mountain to the north east of Relleka and is excited about finding a new cave. Follow him as he leads you into the cave then talk to him again and he'll tell you that he thinks he might have spotted some armour frozen in ice which he thinks will help him to complete The Fremennik Trials.
