(Earth) 2006 = Ivan Kindobor is born.

(Earth) 2046 = Ivan Kindobor leads a team of scientists who dissect the Xorda species after they make peaceful contact with Earth. Meanwhile, they design Isaac, whose objective is to keep Ivan safe during the Days of Fury.

(Earth) 2050-2100 = "Beginning of the Days of Fury." Isaac manages Ivan's life cell chamber in an underground bunker, and monitors the changes to the planet, including the devolving humans and evolving the animals.

(Earth) 2100-3500 = "The First Day of Fury." Although the Xorda's gene-bomb from many years ago intended to preserve the physical environment, it triggers volcanic reactions, sending billions of tons of ash and dirt into the atmosphere.

(Earth) 3500 = The sun burns through the last of the soot; new life appears, and new societies develop, ending the Days of Fury. However, another cataclysm erupts beneath the planet's surface. Beryllium Aluminum Silicate deposits absorb and react with energy of the gene-bomb over periods of time, creating chaos emeralds. Around this time, a chaos emerald is embedded into the chest of Mammoth Mogul, giving him eternal-life. He then establishes the Order of Ixis.

The Sword of Acorns opens the Zone of Silence, releasing Ixis Naugus. The dimensional breach destroys the Ancient Walkers, who are replaced by Aurora, Athair, and Merlin Prower. The death of the Ancient Walkers releases the curse on Mammoth Mogul, setting him free. The Sword and Crown of Acorns are destroyed, removing the Source of All from existence. The Great Harmony is fulfilled by Tails, the Chosen One, uniting all of the chaos emeralds from around the universe into 7, and in turn shaping the Zone of Silence into the Special Zone.
