Elemental Stones, created in the "Great Dwarven Explosion" the death of the Black Ogre Queen

The "Great Dwarven Explosion" was cased from the death of the Black Ogre Queen.  She has ruled the "Underground" and her black ogres since before the "Rise". Her realm has lied under the dwarves in peace for ever... until the Shadowhammer Clan"Deepdiggers" mined too far and discovered her hidden world.

The queen declared war on the intruding dwarves and inflicted wave after wave of her minions with devastating slaughter. The Dwarves were pushed to the edge of destruction, The most powerful clerics from all the dwarven clans, along with their allies...the Elementals, together with the flow and element magic  trapped the queen. She endured for days...the dwarves and the elementals combined their powers...dwarves called and prayed to their gods and elementals pulled power from their planes together as one -- the flow consumed the ogre queen -- her essence imploded, pulling the fabric of the planes inward to nothingness.

Nobody saw the explosion, because they all died during the implosion. The death throws of the Black Ogre Queen blasted the entire dwarven lands and beyond, reshaping the known world. As the dwarves and elementals begin to rebuild, they discover strange rocks with element flow abilities -- "Elemental Stones".  The "death" of the Ogre queen caused the elemental planes to fuse with the physical world. This fusion of planes lasted for only seconds...scared the mountains leaving powerful element flow trapped within. These stones changed Corron.
