Summary:Adventures of our favorite characters in a different universe which involves AI ruled government, and The Reapers.(buff Humanity, buff Council race, and buff Reapers.)

Note: this is my first time writing a fanfiction so please be aware. And I am aware of my bad english grammar, because that's not my native language so thank you for reading.

Timeline:

2040-2050AD: First sentient AI is created and granted the same human rights, Mars is colonized which comprised of 80% Synthetics and 20% Human inhabitants.

2055-2097AD: The discovery of how to creating both Matter and Anti-Matter. Now it's easy to get unlimited materials.

2099-2285AD: Humanity finished the Construction of the O'Neill Cylinders around the Gas Giants, the discovering of how to arrange matter to molecules, and the establishment of United Synthetic Human Assembly (USHA). The discovery of the Prothean data cache on Mars colony during mining/tera-forming.

2286-2292AD: The discovery of mass effect physics after decyphering the beacon, and the discovery that the ice moon of Charon is a Mass Relay. Scientist are quick to discover that element zero is not naturally occurring after studying it's property. The invention of Matter Fabricator. The Construction military infrastructure begins this period.

2294-2301AD: The Anti-Matter Fusion Reactors are online used for energy production, successful synthesizing of element zero is now on full production, and the invention of Wormhole Drive.

2302-2347AD: The slow colonization begins, one system after another. the study of relay FTL network, construction of a Jupiter Brain in Arcturus is complete and it serves as the capital of USHA is completed.

2405-2499AD: USHA begins the Construction of a Dyson Sphere.

2500-2576AD: The Construction of a Dyson Sphere is finished.

2577-2684AD: The establishment the Black Mesa Research Organization (BMRO)

2685-2799AD: Miniaturized Relays are created for goods transportation.

2800-2847AD: the USHA finished the Construction of the Giant Ring World around the Cooper Star System for more Human Habitats.

3567-3573AD: First Contact War occur when Turians tried to invade a USHA colony world of Shanxi this results to the Six Year War, in which the Turians lost all Seventeen Colonies, the Citadel Council offers a ceasefire to end the conflict. The Citadel Council surprised to learn that not only the USHA created AIs but they are govern by them.

3574-3590AD: USHA officially ends it's expansion in the galaxy and currently dealing with pirates and slavers in Traverse trying to enter it's territory.

Codex:

USHA: The United Synthetic Human Assembly ( USHA) are governing body of both Humanity and Synthetic, it comprised two AI decision-makers Gaia and Architect given there respective ideologies, and the Council a group of AI that creates laws, and Human politicians that leads 237 Nation Colonies each.

Synthetic AI: Sentient artificial intelligence, capable of imitating human behavior, having different personalities, due to how there artificial neural network is copied structured of human brain.

O'Neill Cylinders: These structures Ranging is from 15 km to 500 km in diameter they dwarf the Citadel Station terms of size. They are made of steel and graphene, and modern structures now made of synthesized metals and other artificial minerals.

Matter Fabrication: Method of synthesizing matter and anti matter for the materials in Habitat construction and Building Colonies and mega structures.

Anti Matter Fusion: Method of using anti hydrogen molecules and fusing them with regular hydrogen molecules using upgrade standard Tokamak fusion reactor.

Dyson Sphere: The use of 175 million km diameter sphere around the star to capture more of it's energy production.

Ring Worlds: A Large Megastructure of 945 million km of circumference, these Habitats are build for large manufacturing and homes for trillions of Humans and Synthetic alike.

Miniaturized Relays: It only use as to transport material goods and as public transportation around the galaxy.
