After battling and imprisoning the Old Gods, the titanic Keepers set out to repair the damage Y'Shaarj's death had caused. At the continent's center, where Y'Shaarj had settled, an immense hole was torn as Aman'thul ripped Y'Shaarj from the planet's crust, and from which tremendous amounts of arcane energy - the very lifeblood of the world-soul - now seeped. The Keepers closed the wound in the form of a lake of scintillating energies. The lake, which they named the Well of Eternity, was to be the fount of life for the world.
Its potent energies would nurture the bones of the world and nourish life to take root in the land's rich soil. Over time, plants, trees, monsters, and creatures of every kind began to thrive on the primordial continent. As twilight fell on the final day of their labors, the Titans named the continent Kalimdor: "Land of Eternal Starlight" in their language.
The waters of the Well of Eternity would coalesce in a select few places and create gigantic enclaves of life that Keeper Freya would take care of. It is from these magically nurtured places - Un'goro Crater, the Vale of Eternal Blossoms, Sholazar Basin - that the Wild Gods would eventually emerge.
10,000 years ago, while the War of the Ancients was raging on, Sargeras' failed entrance through the Well of Eternity caused the unstable portal within the Well's depths to explode and ignite a catastrophic chain of events known as the Great Sundering. The massive explosion sent massive quakes ripping through the tortured earth and the surging Well of Eternity buckled in upon itself and collapsed. The resultant catastrophic explosion shattered the earth and blotted out the skies. As the aftershocks from the implosion rattled the bones of the world, the seas rushed in to fill the gaping wounds left in the earth. Nearly eighty percent of Kalimdor's landmass had been blasted apart, leaving only a new, raging sea, and the Maelstrom - an eternal storm of chaotic energies at its center, surrounding a handful of major continents and scattered islands: the Eastern Kingdoms, the Broken Isles, Pandaria, Northrend, the remnant still referred to as Kalimdor and many other islands.
Currently, the ancient landmass known as Kalimdor would be called a supercontinent since all known lands on Azeroth were once a part of it.
- Kaldorei Empire
- Empire of Zul
- Mogu empire/Pandaren Empire (Pandaria)
In the RPG
- World of Warcraft: Chronicle Volume 1 hints that the Kalimdor landmass wasn't the only continent on Azeroth. World of Warcraft: Chronicle Volume 3 however states that the night elven empire was located on Azeroth's single landmass.
