Sonic's World

Mobius is the homeworld of the Mobians, Overlanders and humans. Recently it was discovered that Mobius is actually a future version of Earth (in an alternate dimension). According to this universe's timeline, Earth's year would be approximately 14,016 CE, with Mobius' calendar year at mid-late 3237. It is still unknown exactly what was the starting point for their calendar, but its was likely calculated using what the Echidna Tomes call the Days of Fury. Mobius has endured many conflicts, including the Great War, the war against Dr. Ivo Robotnik and subsequent war with Dr. Eggman, and a failed attack by the Xorda. Much of it remains under the control of the Eggman Empire, though some sections of it remain free from its tyrrany.



Prehistoric
Approximately 12,000 years ago, during the 21st century of the "old world" when Mobius was still known as "Earth", an alien race known as the Xorda came to the planet to offer an alliance to its human population. However, the emissary they dispatched was captured, studied and subsequently dissected by a group of scientists led by Ivan Kintobor, a leading scientist at the time. Ivan had hoped to use the captured alien and its technology to produce the robot Isaac as well as numerous other creations. His methods however proved antagonistic towards the Xorda. In retaliation, the aliens bombarded the planet with Gene Bombs with the intention of exterminating all life on the planet. The bombs had an unforeseen side effect however. The human population underwent a de-evolution, forming the four-fingered Overlanders seen on Mobius today, while the rest of the animal kingdom experienced a rapid evolution, forming modern-day Mobians. (StH: #124, #148)

Early History
Approximatly 10,000 years ago, the planet suffered a massive environmental cataclysm. The Gene Bombs were supposed to preserve Earth's environment as it was when it was attacked. However, their interaction with the planet caused massive volcanic reactions, hurling billions of tons of ash and dirt into the air. This is what is chronicled as the First Day of Fury in Echidna theology. The Days of Fury continued to affect Mobius for thousands of years, right up to modern day. The Echidna Tomes describe them as "natures way of adjusting to environmental changes it undergoes over a certain duration" according to Athair. Prior to the Day of Fury which happened in the year 3235, Athair stated the last recorded Day of Fury happened some "twelve hundred years ago". (StH: #148, KtE: #12)

Shortly after this cataclysm, the event known as the Coming of the Chaos Emeralds (which lead to the extinction of the Mobosaurs) occurred - a direct result of the Gene Bombs' radiation blending with beryl deposits deep within the planet's surface. This gave birth to the omnipotent beings known as the Ancient Walkers and provided immortality to Mammoth Mogul, when one of the descending Chaos Emeralds embedded itself in his chest. (StH: #148, TMS: #3, SMM)

Approximately 9,700 years ago, the Echidnas were already well developed in their colony of Albion. The Albion Knights of Aurora found themselves defending the planet against the wizard caste known as the Order of Ixis, which was bent on world domination and was subservient to their founder Mammoth Mogul. Despite the Order's incredible powers, the Albion Knights successfully defeated Mogul during the Forgotten War, effectively wiping out all of the Order of Ixis but him and three members: Agunus, Nusgau, and Suguna. The latter three wizards merged to form the individual wizard Ixis Naugus thousands of years later. (StH: #66, #163)
 * The 300 year period between the Coming of the Chaos Emeralds and the Forgotten War is based off Mammoth Mogul's look when he was 300 years old, depicted in the Mecha Madness special, due to him having the same look during the Forgotten War depicted in StH: #163. This is only a rough estimate.

Developing Societies
Approximately 1,000 years ago, the Echidnas in Albion had already ventured out into space, exploring Saturn and its moon Europa. (KtE: #12, #30)

Approximately 600 years ago, a White Comet hurling towards Echidnaopolis in the continent of Downunda was discovered by the Echidna scientists Jordann and Kayla-La. Using their knowledge of the Chaos Emeralds, the two scientists managed to use the Chaos Emeralds' powers to lift their city into the sky, after the Fire Ants dug underneath the city to separate it from the continent — thus creating the Floating Island. (StH: #34)

Meanwhile, the other Mobians learned from the Echidnas on how to structure themselves into societies. One Mobian, Alexander, decided to pool the various groups resources and knowledge together to form a single society. While the Overlanders proved too violent in nature to be included, and the Echidnas chose to exclude themselves from joining the group, the other Mobians pulled together and created Mobotropolis - the first multicultural city on the planet.

Measurements

 * Weight: Measured in Stone (1 Stone = approximately 6.35 Kg or 14 lbs)
 * Height: Measured in Marks (1 Mark = approximately 1.4 cm or a little over 1/2 inch)
 * Month/Day Calculations: This is to be applied when looking at a characters profile. (Example: if a character was born Day of birth: 162, that would work out to June 11). Using the chart links below, the month and day of a characters birth can be found:
 * January- 1 through 31
 * February- 32 through 59
 * March- 60 through 90
 * April- 91 through 120
 * May- 121 through 151
 * June- 152 through 181

 * October- 274 through 304
 * November- 305 through 334
 * December- 335 through 365

Background Information
The exact date of the Mobian calendar is unknown. However, the year is currently mid-late 3237. While it would have been 3238 if Sonic had spent a full year in space, StH: #155 had Tails state he was still eleven, and in StH: #157 Dr. Eggman's computer monitor clearly showed the year as 3237.

The following is a rough estimate of what issues take place in what year:
 * 3235: StH: #1 — #57
 * 3236: StH: #58 — #125 (3236 began at the very latest in issue #68 when Sonic turned 16)
 * 3237: StH: #130 — *comics ongoing*
