This earth wheel. Its in peices correct? Well the Shrine to Grumbar in Sanctuary has gotten its hand on apeice of an artifiact that could well be formed into a wheel when all the peices are placed together.
I'm pretty sure the whole thing was once in the hands of the grumbar priests at the hold in this place. They were stolen by things called the chosen, at least thats what we were told.
I reckon tehy musta used some kinda magic means to find it. Dunno how they just seemed to know where it is. If'n ya can help some way in that I'll get you one of those stones.
I'll check back here occasionally for your response. If ya wanna meet me personally that can be arranged too.
