The Coming of the Chaos Emeralds was an event which occurred nearly 10,000 years ago during prehistoric Mobian history, which resulted in the extinction of the Mobosaurs and the arrival of the green Chaos Emeralds on Mobius.

The Chaos Emeralds arrival on Mobius happened roughly 11,950 years ago, during the Saurian Age in which Mobosaurs dominated the planet. Mysteriously, the sky turned green and the green colored Chaos Emeralds rained down on the planet. This resulted in bizare weather changes which wiped out the Mobosaurs. However, three Mobosaurs, later known as the Ancient Walkers, managed to survive, having obtained Chaos Emeralds during their arrival on the planet and gained god-like powers, wisdom and insight from the emeralds.

Ages after the time of the Mobosaurs, the Mobian Mammoth Mogul discovered a Chaos Emerald. Somehow, the emerald became imbedded in his chest, granting him immortal life and a far greater intellect than his other Mobian counterparts. Mogul went on to create the Order of Ixis, a group of beings who mastered the Ixian Magics and partially the Chaos Force and were loyal only to him. During their bid for world domination, the rapidly evolving Echidnas grew to act as a rival power. The clash of the two resulted in the Forgotten War, between the Order of Ixis and the Albion Knights of Aurora. (StH: #163, SMM)

Since then, the Chaos Emeralds have been a source of power and a reason for conflict throughout Mobius. From the ascension of Angel Island, to the reign of Dr. Ivo Robotnik and his bid for world domination, to Mammoth Mogul's attempt at bringing about his world order. Recently, the Great Harmony caused by the Chosen One resulted in all of the Chaos Emeralds in the universe to be sent into the Zone of Silence. (StH: #13, #35, #56, #169)
