Flooding of Terisiare

The Flooding of Terisiare was an event that occurred on Terisiare over several decades following the World Spell.
==Description==
The warmer temperatures caused by the World Spell affected the entire plane of Dominaria. Still, nowhere was this as tangible as on Terisiare, where four glaciers had gripped the land for millennia following the Sylex Blast. The now sudden retreat and gradual disappearance of these glaciers - the Great Glacier, Ronom Glacier, Raynor Glacier and the Boreal Glacier, left behind a ground-down landmass where before there had been hills and valleys and even mountains. Additionally, the meltwaters from the glaciers were so long locked into the masses of ice that they were now free to run across the continent. 
Gradually, the Sea of Laments formed in the middle of the continent, drowning the Great Desert, Northern Wastes, Frost Marsh and Tresserhorn, and splitting the continent apart into smaller islands. Fyndhorn and Kelsinko, previously risen from the seabed, were once again reclaimed by the ocean, forcing their inhabitants to flee. As the Shattered Sea formed over the sinking lands, Jaeuhl Carthalion and Kaysa led the Fyndhorn survivors to Yavimaya and made peace with Multani and the intelligent gorillas there. After the flood, the only remnant of Fyndhorn was the new island of Korlis. The Shattered Sea would continue to rise, and eventually also swallowed the plague-infested, vampire-ridden city of Krov.Jeff Grubb (2000) - The Shattered Alliance, Wizards of the Coast
The Great Glacier, having previously land-locked Lat-Nam and covered the Halquina Mountains of Almaaz with tons of ice, left behind only a sparse archipelago consisting of former mountain tops, with the Lat-Nam Straits lands like Iwset and Jehesic having been scoured away and lost to the sea. The site of the School of the Unseen too fell beneath the waves, although it had already been ruined and abandoned by this time.
The Boreal and Raynor glaciers too retreated, leaving the Balduvian Steppe on a lone peninsula, and the Adarkar Wastes as a mere remnant on the edge of the sea.
However, not all of the effects of the flood were destructive. Many new civilizations flourished with the warmer weather and the fertile ground, including New Argive with Argivia and Epityr, Gulmany with Efuan Pincar and numerous smaller city-states, and the island of Jharth.

Although Terisiare suffered the most dramatic effects of the Flood Age, climate change was also noticeable in places as far away as Jamuraa. During the flooding period, the glaciers that towered over the Blue Mountains rapidly evaporated in the soaring heat. Almost wiped out in flash floods, the hardscrabble hill tribes of Tirras who survived found all their topsoil washed into valley bottoms, which proved fabulously fertile. As food became plentiful, so did children, and Tirras's population exploded.Clayton Emery (2001) - Johan (novel), Wizards of the Coast
