Okay - crackhead theory I never got to confirm because I know things Rowan didn't. Supposedly, someone said something along the lines of "If the four tools were collected by the wrong individual, destroy Levinkan." My thought - the Levinkan Warp Controversy is true. That person could undo the Great Fissure, bringing the continents back into a supercontinent of Ywrought. The issue is that Levinkan would inevitably crash, since it's on the wrong side of the realm now!
