So I don't spoil too much if you have done this then you will know from my basic explanation.
When doing mage quests you will come across a gauntlet in the midden which leads to a treasure map.
I had to reset my whole game due to a crash so I decided to go straight for the rings and then head to the midden instead of the normal way, I did release HIM.
I have found the location and have verified it by wiki since nothing was showing first time around, with no chest showing I need help.
Do you have to do something else before it shows, am I in the wrong place or is this just a quest bug?
