Turn 4 ends with a bang.
A cliche, I know.
A bad cliche, considering what has happened this Turn.
Yet there it is.
It is a bang a lot bigger than Tambora was.
It is seen in Rauxes, a thousand miles to the north.
It is heard on the Isle of the Phoenix, 5,000 miles away.
In one gigantic explosion, the Glorioles blow themselves up.
The soaring fireball, composed of uncounted billions of tons of rock, magma, and dust, rockets up into Oerth's stratosphere, clear up beyond it into near space.
A red, dripping glow is seen as a geyser of lava 2 miles high fountains into the sky.
There is an enormous earthquake, and the whole of the eastern Flanaess shakes violently.
The people of Nulbish and Torrich watch in awe as the southern heavens fill with fire.
The people of Sunndi watch briefly, then they are engulfed, for the flows head southward, and whelm all of Sunndi in pyroclastic blasts, followed by a sea of molten rock.
A GIANT rending and cracking sound is heard.
The Flanaess breaks apart, from central Idee in the west, across the Hollow Highlands, then northeast around the geyser, and eastward across southwest Medegia to the sea.
The geyser grows wider and wider, and the ocean roars in on both sides, only to meet vast amounts of lava storming up through the broken crust of the planet and from the great geyser.
Explosions follow, and clouds of steam cover all of the southeastern Flanaess.
But still the great geyser, a mile across and two miles wide, fountains into the heavens, and the molten rock pours west, east, and southward.
Building mountains where no mountains existed.
Remaking the landscape utterly.
Sunndi, passes forever into Flannae history.
The Glorioles, pass forever into Flannae history (or, rather, a far loftier and greater range will replace them, and truly earn the name given the old, small area of mountains.)
The storm giants of Starmont, pass into history, unable to escape, the eruption catching them without warning.
And the rift widens rapidly, the oceans flowing in to fill the gap, while the entire southeastern peninsula, cramming millions of years of geological movement into a few days, moves over one hundred miles south of it's current position.
The freshwater sea that had been the Vast Swamp is carried with it.
The Tivanot Peninsula twists, turning northwest to southeast, and moves 50 miles southeast of it's current position.
The northern landmass slams into Hempmonaland, as the Tilva Strait ceases to exist.
The continental shelves groan in protest, buckle, then shatter, sending more massive earthquakes through the whole region (fortunately, far away from any settled land, for they are greater than 10 on the Richter Scale.)
Volcanic eruptions and explosions occur all along the clashing line, where Hempmonaland meets the peninsula of the Flanaess.
And a new set of mountains begins forming south of the freshwater sea that had been the Vast Swamp.
So great is the eruption of lava that there is no place for it to go, and Sunndi is filled with an inland sea of lava, a thousand feet deep, hundreds of miles long, and hundreds of miles wide.
The heat from this lake, hundreds of thousands of square miles in size, turns the climate of all of the southern Dark Union into an equatorial steambath.
The word autumn is erased from the vocabulary.
The ocean currents flowing northward past the Sea Barons and the Lendores turns warm, then hot (over 100 degrees), producing storms of ungodly proportions.
Magic becomes a necessity, and not an option, for survival in these places.
Travel by ship becomes impossible, unless very great magic (7th level or higher) is employed to get through the storms.
Hurricanes with winds one would not wish to imagine form over the open ocean, sending massive waves in all directions, flooding the whole eastern coastline.
