History (Kalos Universe)
- Mount Toba, a volcano near the eastern coast of Lemuria, erupts in spectacular fashion: the biggest explosion in the last two million years. The volcano spews enough sulphur into the atmosphere to lower world temperatures by several degrees, and enough molten rock to cover an area the size of Great Britain to a depth of 10 meters (3 feet). It also produces vast amounts of ash. Driven by the winds, clouds of white Toba ash cover huge swathes of Asia, including Lemuria and much of the Indian subcontinent. Humanity nearly becomes extinct.
- The island civilization of Lemuria vanishes beneath the Indian Ocean.
- Global warming marks the beginning of the Holocene epoch. The melting of the Laurentide Ice Sheet and other ice sheets cause world sea levels to rise 35 meters (110 feet).
- Scores of large mammal species ("megafauna") abruptly become extinct.
- The island civilization of Atlantis vanishes beneath the Atlantic Ocean.
