The Return to Earth is a major event in the history of the World of Baten Kaitos that occurred at the end of the events of Baten Kaitos: Eternal Wings and the Lost Ocean.
Events[]
After the defeat of Malpercio atop Cor Hydrae, at least four (Mira is not shown) of the Five Great Nations, Wazn, and possibly other islands, began their descent back to the now unpolluted Earth. Sadal Suud, Diadem, Anuenue, and Alfard are gently guided down by the giant Sibling Gods, speculated to be a gesture from the five siblings who founded Malpercio. After Xelha releases the Ocean back onto Earth, Wazn soon follows suit coming to rest in the middle of the Ocean, causing a wave.
Causes[]
It is not known exactly which combination of the following factors caused the islands to fall. Many feel that it was a combination of all three of the following:
End Magnus[]
Before Kalas and his friends could infiltrate Cor Hydrae, they needed to breech its outer barrier. This was done by having the Great Nations use the remaining powers of their End Magnus that kept the island afloat to fire beams of energy that shattered Cor Hydrae's barrier. The End Magnus provided the power necessary for the islands to float and much of their power had just been spent.
Malpercio's Defeat[]
Malpercio, the being whose power was contained in the End Magnus, had finally been defeated; not just sealed as before. Some believe that the defeat of the Gods (Wiseman 20 years prior, and now Malpercio) factored into ability of the islands to return to Earth, absorbing his leftover power in the islands.
State of the Earth[]
Over the last 1000 years, since the War of The Gods polluted the Earth, the Taintclouds had been used to slowly cleanse the Earth, making it habitable once again by humans. That point had come, accelerated by Malpercio's defeat some speculate, by the time the Return to Earth took place. Some feel that the system the Ancient Wizards designed for the Nations to remain afloat would not have allowed a return to the polluted Earth.
