400,000 - 4,000 B.C.: Mammoth Mogul is born.
9,700 B.C.: The Order of Ixis is formed by Ixis Mogul. They are a religious cult of sorcerers and sorceresses that worship Ixis the God of the underworld, dead (Like Hades/Pluto), and magic.
3,500 B.C.: The Rise of Early Human and Mobian Civilizations including the birthplace of Echidna civilization, Albion, located off the coast of Avalon is established as is the worship of the Gods, Athair (King of the Gods and God of men, Kings, law, order, and justice like Zeus/Jupiter), Aurora (Queen of the Gods and Goddess of marriage, women, childbirth, heirs, and Queens like Hera/Juno) and Enerjak (God of War, Bloodshed, and Violence like Ares/Mars).
3,200 B.C.: The Forgotten War. The Albion Knights of Aurora and The Order of Ixis clashed for control of the planet resulting in an Albion victory and destruction of the Order of Ixis.
2,000 - 1 B.C.: Three groups of Echidnas left Albion to explore the world. A select group of Scientists travelled to Tralius and performed inhumane experiments on the local Tasmanian Devil population mutating them into Mobinis (Wildlife such as the Flickies, Lockies, and other animals sealed in Eggman's capsules and robots.) known as Tasmanian Devil Dogs. The Knuckles & Nocturnus Clans travelled to the continent of Soumerca where they colonized and built the city of Echidnaopolis.
The Knuckles Clan and Nocturnus Clan fought various battles with the native Felidae and eventually the two clans turned on each other and the land was caught in a three way war for control of Soumerca. At some point the Nocturnus Clan was banished to the Twilight Zone during something known as The Argus Event leaving only The Knuckles Clan and Felidae to fight. Close to the end of the Epoc, the daughter of Chief Pachacamac, Tikal discovered the Master Emerald Shrine and Chaos Emeralds along with the inhabitants of the shrine, The Chao. Who were being protected by Chaos (God of the sea, rivers, floods, droughts, and earthquakes like Poseidon/Neptune and The Chaos Energies) these two became unlikely friends and together they cared for and protected the Chao from the ongoing war. Though this friendship came at a cost, eventually her Father learned of The Shrine and the Emeralds and decided to try and take them for the clan.
0 A.C.: When Pachacamac led a charge on The Master Emerald Shrine he harmed his daughter and killed many of the Chao that she and Chaos were protecting. Which filled Chaos’s heart with rage, resentment, and he absorbed the negative energies of the Chaos Emeralds and laid waste to the continent of Soumerca. His wrath was stopped when Tikal used the positive energies of the Chaos Emeralds and sacrificed herself to the gods and goddess and sealed herself and Chaos inside the Master Emerald, the resulting energy of having a god and a now demi-god trapped inside it caused a large area of the surrounding landmass to rip free from Soumerca and rise into the air where it’s stayed ever since.
1 A.C. - 600 A.C.: Echidnas colonize Angel Island and build and a brand new Echidnaopolis.
800 A.C.: Alexander Acorn, also known as Alexander the Unifier and the first of the Acorn lineage established the first monarchy, The Kingdom of Acorn, and the first multicultural city, Mobotropolis, on Westside Island in the Chaos Archipelago.
2858 A.C. - ???? A.C.: The Echidna brothers Edmund and Dimitri are born and grow up to become two of Angel Island’s most renowned scientists and when they developed a way to restore Angel Island back to it’s place on Mobius using Dimitri’s Chaos Syphon Suit to drain the Master Emerald of its energies which kept the Island aloft. Their plan is denounced as heresy by the High Council and denied, Edmund gracefully accepted the verdict while Dimitri recklessly and stubbornly decided to go ahead with the plan. As he drained the Master Emerald it’s energies were transferred to him amplifying his Chaos Control abilities tenfold; When Edmund caught wind of his brother's actions he tried stopping him and while he was able to deactivate the suit he was also affected by the Chaotic Energy. His own Chaos Control abilities were amplified and was given a white crescent marking on his chest and was now able to detect the Chaotic Energy of the Master Emerald and Chaos Emeralds. Following this Dimitri was hauled away to prison and Edmund became the first Guardian of the Master Emerald, while he was imprisoned Dimitri learned to use his new powers and used them become the living embodiment of the Chaos God Enerjak, escape and use the city’s own defences against it and effectively enslave the population.
While short-lived during his reign as dictator of Echidnaopolis, Dimitri established his technocratic army known as the Dark Legion, married Cynthia-Wa and had a son named Menniker, abducted his brother and imprisoned him and all enemies of the state in a prison built on Mount Fate known as the Dark Tower. When a resistance was formed by the citizens of Echidnaopolis to try and defeat him they allied with the Fire Ant Council and Dingoes to take down their common enemy, as soon as they had the numbers and a plan set they launched an assault on the Tower while the Echidnas and Dingoes kept the Legion occupied allowing the Fire Ants to dig out the Tower’s foundation. It collapsed in on itself killing most of the Legion and, thanks to Enerjak making him invulnerable and the walls of the Tower immune to Chaotic Energies, trapping Dimitri under the rubble.
The remaining members of the Dark Legion surrendered and were subsequently either imprisoned or executed, Edmund took in his nephew and raised him alongside his own son, Steppenwolf. Menniker frequently visited the rubble of the Dark Tower to pray and swear revenge for his father’s supposed death, when he was a teenager and Edmund began training him to be a Guardian alongside his cousin he began to receive telepathic messages from his father telling him to follow in his footsteps and revive the Dark Legion. As their training continued Menniker played along while he began forming plans to break the living members of the Dark Legion out of prison and take over, when his training was near completion he faked his death and set his plans in motion. After freeing the Legionnaires they began a Civil War on the echidna population over time they started taking the upper hand and the High Council, desperate to end the strife, started considering the option of surrendering to the Legion’s reign till Edmund and Steppenwolf came to them saying that they would handle it.
During a Dark Legion rally the Father and Son Guardians approached the Grandmaster still unaware it was Menniker and attempted negotiations but when Menniker revealed himself to them, explained his reasoning behind his actions and realizing neither side could be convinced to join the other a fight ensued. The fight was ended by Edmund sacrificing himself to seal Menniker and the Dark Legion away in the Twilight Zone, afterwards Steppenwolf took over as Guardian and Echidnaopolis isolated themselves. Steppenwolf married Eri-Ka and had a son named Moonwatcher and together over time the family formed the Brotherhood of Guardians who would protect the Master Emerald and Angel Island from any and all outsiders with malicious intent as well as protect Echidna interests on a global scale.
