Before I get to the lore of this place, I want to address some main facts for our fellow Sonic fans.

1. TTW Sonicverse (later - TTWS) is not AU, parallel dimension or headcanon of your well known original. It is a separate multiverse that belongs to it's own franchize minorly, yet it does not mean it's lore is unimportant or that my Author is trying to claim company's rewritten work. Read All-Fiction Tales by #harine-tales tag

2. TTWS has no Master Emerald at all.

3. TTW mobians are slightly taller than their initial counterparts due to slight different anatomy, disabling anyone from ability to SPIN, removing such options as spindash, drop dash or homing dash series.

4. TTWS is finite, consisting of 1001 universes, not all of them focused on "Mobius"

5. TTWS initial universe implies that mobians came after humans due to certain events I will list down later

-------☆------

Geography

Mobius consists of 4 "countries"

- Arco Federation

President based region with the most of cities and humankind

- Areha Empire

Mobian-built land, one of first places where mobians started to appear and cooperate

- Cali Kingdom

Exile country of mobians and very few of people, who don't trust Arco Federation but seek no spilling blood for whatever the reason could be

- Eggman's Territory

Pretty much the untouched lands, not so long ago taken by Ivo for building Metropolis city citadel

Planet's history

Origin

TTW Earth-Mobius events branch begins from one dimensional God creating this multiverse and Chaos Emeralds.

4 billion years ago

Chaos Emeralds are given to the first civilization in the universe

Phantaiser, the outerversal God, builds a church to keep Reality Stones and inhabits it with monsters, mazes and such.

A stranger with Godlike powers takes a few Emeralds and copies them across the multiverse to aid him in creating Haron, Taron and many universes ahead of time.

3.5 billion y.a.

Blastaro prototype is found and trained by ApyRyzor. After some time, he is promoted to guard Reality Stones.

A powerful fog appears from nowhere, sealing most dimensions in the outerverse and corrupting weak Godly minds, including Rezataph.

3 billion y.a.

Rezataph's mind was corrupted by the Mist and his own power lust, so he attacked Blastaro for Reality Stones. Phantaiser took the fight instead of Blast and sealed his brother in Hell Dimension. Fight reaches a planet with emeralds so they scatter across timespace.

71K y.a.

Earth as we know it was formed. Classic human history soon starts.

2070

Humanity finds another livable planet, but only a limited number of them could be privileged to depart.

2089

Humans that left on the planet, started a war to reduce the amount of the planet's resources consumed. Nuclear bombs were exploded in places they were intended to be launched from.

2093

After endless wandering, one of the gems falls on the destroyed First Earth and renowns its plant life and animal DNA, so they turn into “mobians”.

2097(-2132)

With humans, who survived the war, they made a truce to rebuild the planet into what we know as Mobius.

2099

Knuckles the Echidna is born at Angel Island.

2105

Gerald Robotnik is born.

2117

Humans who had lust for Chaos power, excusing it with humanity progress, founded ARK. 1924th, young Gerald Robotnik joins ARK.

2116-2127

Government and ARK started a mission to find the other 6 signatures similar to the Emerald they already had.

2124

Gerald Robotnik joins ARK

2128

When Mobians found out about such news, they feared this power and as soon as they could, managed to steal the gems and use them to reset human memories for a few decades backwards. Humanity now believed they were those who departed on another planet and those aliens (mobians) accepted them. History of humanity was rewritten.

2130

As the leader of such a steal & reset group, Knuckles hides 4 C.E. on Angel Island, entrusting the other 2 being hidden somewhere else far away. Humans got only 1 Chaos Emerald in their hands.

2130-2200

Government of Arco Federation, going from ARK’s research, decided to make a battery first, and then - a currency, charging lit golden rings with its energy.

2132

The reset’s efficiency however could not last too long. ARK did find Mobians to be more adaptable units to Chaos energy than themselves, so they started to make clones of living units and other tools to tame Chaos Emerald’s power.

2150

My grandpa, Hirogami was born in Taiyo Village (Areha Emperya)

2165

Project ARK-U (Ultimate) starts as ARK actually finds one of two randomly hidden Chaos Emeralds.

2171

Hirogami meanwhile finds the second hidden Emerald.

2177

Ivo Robotnik was born.

2184

Project ARK-S starts just as advanced cloning was mastered. The S type meant “scout” which was intended to travel the space by oneself in search of livable planets.

2199

Project ARK-S19 (Sonic) escapes with Project ARK-T04 (Tails). Maria Robotnik is suspended in freeing them and trying to help Project ARK-U34 (Shadow) as well, so she was killed.

Dr Ivo is sent to catch Sonic, but he turns against ARK. Sonic, Eggman, Knuckles, Tails and Shadow destroy ARK together.

2200

After the events of 2199, President of Arco was suspected of assisting a crime against living individuals and was forced to leave his post.

Considered as dangerous, currency of Chaos Rings was stopped and given away to Sonic and Tails

2201

As Dr. Ivo applied for being voted in; few voters who did not like him, gave him a nickname “Eggman” making that a meme. Unluckily, even such “popularity” did not help him in winning so he left Neopolis.

2202

G.U.N. was founded by a new President, as Shadow joins it before Rouge does the same.

2200-2205

As Ivo went into exile, he started building his own city apart from any country - Metropolis. Tails assists poor doc with building, but they argue over ecological topics and Tails gets “fired” by Eggman.

2206

The year when I was born.

Dr. Ivo builds his own metal prototype of Sonic, suggesting blue blur to test that thing in its limits, to which Metal lost but still gathered some data in untouched HDD. By that moment yet, Iv o needed to have Metal Sonic for what ARK needed him but without using Sonic himself, to which latter did not mind.

2207-2210

Ivo starts to build his own spaceship alone to get to better resources, reconsidering fox’s words, to these new Tails was glad, however they still did not want to find common ground, because Ivo would not withdraw his ecologically inefficient factories anyway.

2210-2211

After a short expedition through space, Ivo finds out his own power is not enough for farther travels, but in the meantime he already built quite an army of robots which arrived to Mobius with him

Ivo goes to Angel Island in order to reason with Knuckles over Chaos Emeralds, but echidna stubbornly declines. Infuriated in his inability to prove to the mobian that “his Empire is made only to benefit the world selflessly”, Ivo snaps and attacks Angel Island to which he was effortlessly stopped.

2212

Not giving up on doing the best for everyone, he tries to build an artificial sky over Mobius, which could do any weather needed or do a better filtering of starlight’s ultraviolet. But his experiment fails and “sky” starts to behave chaotically, unable to be shut down, except by force Eggman did not have.

Completely losing reputation and any hope to recover his family’s name, Eggman totally gives up on helping humanity kindly.

2212-2214

Eggman returns to colonizing planets he could, in order to get better resources.

"Golden" Sonic (first time coming to Super form) fights Metallix and wins.

2213

New Eggman’s version of Metal (Metallix) is sent to Mobius mines, raiding it as a “new Emperor’s” territory, while other bots take over North Pole.

2214-2215

Eggman returns to take more territory for Metropolis’ expansion and improvement.

2215

Mecha Dino arc, where Eggman goes back in time with Chaos Emeralds to take a truly accurate model of dinosaurs for hard and large works.

Sonic follows him as they fight and warp occasionally, also revealing the truth about reset, after which Sonic defeats Eggman’s creation.

As a result of this clash, for next time Eggman decides to make mecha dragons for errands between colonized planets.

2216

Upon his travels, Eggman comes across the ruby buried under old temple ruins in Cali Kingdom. Infamous events of Sonic Forces occur. No cheap shit Zavok, no scared Tails, not too much power of friendship this time however. (Well, in that continuity, Zavok and Chaos do not exist anyway).

2217-2218

Eggman desperately tries to check the multiverse theory in practice to breach the bounds of the home universe and find something else. To his surprise, he succeeds in contacting his alt self

Eggman learns about 6D ether and makes new fuel out of it, not just to speed up and buff his combat robots but also travel outside his universe into 6D.

Meanwhile for mobians, Phantom Hunt arc begins to seek the lost original Phantom Ruby, not without Eggman’s robots and even myself a little.

2218-2219

Spends time building new robots with his AU selves, gathering more Emeralds than ever before. 35 Chaos Emeralds.

Sonic with the help of Ruby and Chaos energy defeats Eggman’s Council creations, handing off the Ruby to Tails after victory.

Original Eggman gets “home arrested" by Phantom Super Sonic, unable to leave his universe.

2219-2220

With the arrival of Shadow and Tinik as well, Ivo finds out about Path energy, trying to harness and fabricate it into his space dragons, while building a new machine to warp reality and crumble the universe from inside to build it anew.

2220-2221

After yet another failure, Eggman tries to hunt for Reality Stones or the same Planet of Prisms but you know there are guardians far above his league.

2223-2224

As the latest and most insane attempt ever, Eggman tries to absorb/siphon all life energy and knowledge of his AU counterparts to become closer to omniscience but explodes from backfired overflow through his device.

As a result, an entity of Path, Chaos and Ivo’s irredeemably corrupted and incomplete soul fusion is formed. It transcends into the future, taking over Silver first, forcing Knuckles to try separating the entity from poor hedgehog and seal into Emeralds to swear never ever using them.

But unluckily his tactic fails and the entity consumes Knuckle's soul, killing him and taking over his body to use 7 Emeralds and become local “Enerjak”.

Sonic and Tails are forced to kill their friend’s body for good without a trace and bury Chaos Emeralds deep on Angel Island.

This is too local pun, I refuse to elaborate
