Many rune-keepers seek the Rune of Restoration, but not all can accomplish their goals alone.
'Well met, ${CLASS}. It is fortunate for me that you have come along. I have a favour to ask of you if would spare a moment. My fellow rune-keepers and I have learned of a foul creature housed within the Sixteenth Hall: the frost-grim Helegfan.
'Many young rune-keepers are seeking this fell spirit, but I doubt any would succeed alone. They will need your help.
'If you are willing, enter the Sixteenth Hall and aid a rune-keeper in this task. Return to me when you have succeeded, and I will reward you.'
This quest can only be completed by helping a rune-keeper on its Legendary Trait quest \qSecrets Long Forgotten.\q
Helegfan can be found in the Sixteenth Hall, at the south-eastern tip of Nud-Melek, just north of the Foundations of Stone.
Ríon has instructed you to aid your fellow rune-keepers with their final task upon the path to obtain a Rune of Restoration.
Ríon is just outside of the Sixteenth Hall.
You should return to Ríon and inform him of your success.
