Long ago, Azeroth consisted only of a massive continent, surrounded by a seemingly endless ocean. This landmass was called Kalimdor, meaning "the land of eternal starlight", by the Night Elves, a nocturnal humanoid race that inhabited it. At the rough geographical center of the landmass stood the Well of Eternity, crafted by the Titans, the creators of Azeroth. Night Elves were lured to the Well of Eternity by its potent magical energies, and eventually settled along its shores. Eventually, elves of noble birth, called the Highborne, including Night Elf queen Azshara, began to study the powers of the Well. Over time, they dwelt too deeply into the arts of magic, and triggered a huge invasion of demons from the plane that interconnects the worlds in the universe, the Twisting Nether. After an epic battle between the demonic Burning Legion and the Night Elves, the Night Elves, against all odds, defeated the Burning Legion, but the Portal at the bottom of the Well buckled upon itself, triggering a cataclysmic explosion. The massive crater was filled by the sea, leveling whatever remained standing after the explosion. Many inhabitants of Azeroth perished, including thousands of Night Elves, but the survivors managed to drift ashore on debris, to the westernmost one of four pieces of the former supercontinent survived the flood. Since Night Elves were not aware of the other "survivor" continents, they kept the name "Kalimdor" for their new homeland.
