Should that be "You can see"?You frown, then drop onto your stomach to examine the edge of the crater from an inch away. Can you see individual grains of the stone crumbling into sand. "Find me whoever knows the most about stone in this Expedition," you say.
... Odd. So..."And the sand? Is it fragmented scoria?"
"No," he says instantly. "Wrong colour completely." He bends down and picks some up, letting it run through his fingers before putting a pinch in his mouth. "Sedimentary silicate, not igneous. Nearest place you'd find this is the southern Dark Lands."
With a tiny fizzle of Divine energy, a tiny piece of rock disappears, replaced by a few grains of sand that tumble down to join the rest of the desert.
This desert is made by Morghur's aura?
That's weird. Morghur doesn't usually make desert, does he? What the heck?
... Is this like some "Reverse the polarity on the deflector dish <insert Treknobabble>!" thing?
Where, if Morghur is in the physical world, he starts turning it into the Aethyr; but if he's in the Chaos Wastes he starts turning it into real-world-stuff?
... I wonder if Morghur actually originates from somewhere in the Dark Lands? (Either the original Morghur, or this Morghur.) Something to do with the Dwarfs that eventually became the Chaos Dwarfs? Or maybe just something to do with locations in the Dark Lands? So maybe Morghur is transforming the area to look more like a particular Dark Lands locale? Or maybe he is bringing a part of the Dark Lands into this area?
Or maybe that was just the Dwarf's way of saying that the sand is weird and something you'd usually find in places like the Dark Lands, rather than a literal sign that some kind of location-switcheroo is going on.
EDIT: How far down does the desert go?
