I thought there was some legend/myth about a Stone in Husafell, Iceland? Then the name kind of followed from the huge-ass natural rocks that lifters pick up.
Something about a guy carrying this massive stone around a sheep pen 3 times to defeat evil, or get some power?
Or maybe it was just a quest a strength or something. Google isn't helping @ the moment.
"Steve confronts a new challenge in Kviahellan: The Pen Slab, that of lifting the original 418-lb. Husafell Stone in Iceland and carrying it around the goat pen, to achieve "fullsterkur" (full-strong) status.
....
Then you board the plane with Steve for the remote, windswept fields of Iceland wherein sits the Husafell Stone, still guarding the goat pen built by pastor Snorri Bjornsson over two hundred years go."
