Timeline after discovery of Prothean base.
-Upon capture of the 4 remaining Prothean's She has a troop transport retrofitted, for in space flight, with an atmosphere, transporting the 4 to earth, and synthesizing their planetary environment through the records of the Prothean home world. The habitat is placed with the rest, next to the would-be human habitat. Skynet takes some genetic material from the surviving Prothean's, and creates 246 males and 250 females. The recreated Prothean's and the survivors are placed in the habitat so as to prevent the extinction of the species.
-2086 CE: The prototype dreadnoughts (1km long, 100 meters tall and wide, armed with 1000 repeating plasma turrets, 1 spinal PMAC, 20 plasma rocket silos, each silo carries 100 missiles) are determined to be functional, though as discovered in the archives knowledge and Skynet's own simulations have their own weaknesses. The Reapers trap was effective though it almost failed to the Prothean's who created semi effective directed energy weapons. The main weakness's lie in the kinetic barriers that is made obsolete by plasma weaponry, as well as the FTL drive which is atrocious in its speeds when compared to the Mass Relays. Resources are to be diverted to the creation of faster FTL methods, as well as energy shielding, and material harvesting.
2100 CE: Skynet's operations bear fruit. Mars as well as Jupiter's moons, and Venus, are now a part of Skynet's manufacturing plants.
Through experimentation an opening 2 meters in diameter was created to the 11th dimension. The probe reappeared, 200 light years from Earth a day later. The drive under goes a refinement and streamlining process in order to be mounted on ships.
Energy barriers were created and can stand up to 10 impacts by a plasma turret, and 10,000 from mass accelerators, though due to a single plasma turret shooting 600 shots a minute this is unacceptable.
For material harvesting, extensive resources were diverted, and a Quantum Molecular Reassemble or QMR was created. It can strip atoms and even protons and neutrons down to the quirks that make them up and recreate them in any manner as long as there is base material. The assembler definitely makes wasting material no longer a problem, though a solution has also been found for actually acquiring the raw material.
If sufficiently large platforms were created in orbit of a star, it would be possible to catch the enormous quantity of material that is ejected form a star on a yearly basis. Trillions of tons of hydrogen and other atoms a year, combined with a QMR would solve any material problems for billions of years. The only drawback is that the stars life is shortened but only by about, 100 years.
2125 CE: Creates its own ship classification that go as follows:
All ships possess a Subspace drive, nanites with blocks of metal in storage to repair damage, as well as energy shielding.
Fighters: These are a modified version of H-K drones. They possess a weaker energy shield powered by a miniature cold fusion reactor. This shield is still strong enough to resist 100, mass accelerator rounds, and 10 plasma shots. The fighter itself is more maneuverable, and has 10 plasma guns on each side of its main body, as well as dual front and rear canons.
The bomber variant switches all but the forward guns out for, missile pods, containing 25 plasma missiles each.
Troop Transports: These are 50 meters long and can hold 100 troops, 1 H-k, 1 Crab, and one Colossi at maximum. The Colossi, and the H-K act as a defense for the transport.
Corvette: 300 meters x10mx10m; theses ships are meant to fulfill scouting, and anti-fighter roles. They are armed with 50 light repeating plasma turrets, as well as 1 anti-ship missile silo.
Frigate: 400m-600mx10-30mx10-30m, this fulfills services for smaller combatants not meant to be used as ships of the line but rather in packs of 7 to cripple targets that get close; 200 heavy plasma repeaters, 4 heavy plasma canons, 1 missile silo, the larger end frigates may be armed with a PMAC.
Cruisers: 700-1000 meters, these are ships of the line, they are armed with 500 heavy plasma turrets, 250 light plasma turrets, 10 heavy plasma canons, 4 missile silos, and a PMAC.
Battle Cruisers: These monsters are the same size as their ship of the line counterparts, but they possess enough firepower to decimate 5 frigate packs. Armed with 1000 heavy turrets, 8 heavy plasma canons, 10 missile silos, and 2 PMAC's, they are surpassed only by higher caliber vessels.
Dreadnought: 2.5-5km long, these capital class vessels, are armed with 5000 heavy repeating plasma turrets, 200 heavy plasma canons, 100 missile silos, and 10 PMAC's.
Carrier: This vessel only role is to carry both fighters and ground troops. They are 3km long, and hold, 500 H-K's, as well as 5000 Hornet/ Wasp attack drones. For ground troops it has 10 battalions of T-800's, 500 Crabs, 50 Tanks, as well as 50 Troop transporters with accompanying Colossi, and H-K detachments. For defense it possesses 50 light plasma turrets, to knock out fighters.
Battle Carrier: 10km, they possess half of the troops, and triple the fighter compliment of Carriers, with anti-capital ship weaponry, with 1000 heavy plasma turrets, 2000 light plasma turrets, 200 missile silos, and twin PMAC's, it is a worthy opponent on the battle field.
Core class vessels: 100km vessels, with over 40,000 light plasma turrets, 10,000 heavy turrets, 20,000 missile silos, 30,000 heavy plasma canons, and 500 PMAC's. This vessel can be used as a point for Skynet to manage all assets it is connected to and in control of. [Never engage this vessel.]
Seed ship: 20km long x1kmx1km, this ship is a "Colony" ship. It only posses' thrusters, a subspace drive, a shield, and 20km cubed of compact nanites. The ship is shaped like a rectangle with a square pyramid at the end. The ship enters the atmosphere of a planet, setts itself in to the surface, and uses the nanites to establish a base of operations.
ODP: 2km diameter stations with, 10 PMAC's, 300 fighters, 200 heavy plasma canons, and 400 light plasma turrets.
Space Stations: 10km diameter stations, that are used as a dock before a ship yard is constructed.
Shipyard: 50km of factories, and material reassembles dedicated to ship building.
2150 CE: The 11th dimension Sub Space drive, is complete and capable of traveling at 5050 light years a day, just over half of what a mass relay can do.
This is tested with Skynet sending a now perfected dreadnought to a neighboring star system 100 light years away, in several minutes. Energy shielding can withstand a bombardment from plasma weaponry from 3 dreadnoughts of similar class for over 10 hours. Mass accelerators are practically useless against the shield.
2175 CE: The first of several Star harvesters is complete, enormous dome circles, with 50km diameters. Already over 50 million mega tons of material are being created each year.
2200 CE: Skynet has "colonized" 400 worlds. Finding it increasingly straining to manage the worlds Skynet makes the decision to allow the T-3000, and T-5000 to become fully sentient with those that were converted from humans retain their personality.
-Skynet's fleet:
Corvettes: 100,000,000
Frigates: 20,000,000
Cruisers: 50,000,000
Battle cruisers: 1,000,000
Dreadnought: 500,000
Carriers: 300,000
Battle carrier: 8,000,000
Core class: 3000
Seed class: 50,000
Troops: 100,000,000,000,000
2500 CE: Skynet possess over 10,000 solar systems.
Skynet can travel anywhere in the galaxy in less than a microsecond.
The mass relay in Pluto's moon has been dismantled.
Any relays discovered are recorded, and unless they are in a system Skynet wants, they are left alone.
Skynet hasn't expanded its fleet yet though it can start creating over a million ships a day if need be.
A new step has been created in the "colonization" process to help prepare for the Reapers. The outer asteroid belts of the system are to be turned in to defensive rings that encompasses the entire system. These rings would vary in diameter and radius based on the system, but they are all 100km wide, and thick. They possess millions of light and heavy turrets, as well as hundreds of thousands of heavy plasma canons and missile silos, combined with trillions of fighters.
2550 CE: Skynet looking through the data that the Prothean archive posed discovers they planned for a race known as the Asari to be the leaders of this cycle and to dominate it.
Sending out a "small" flotilla of 10,000 ships, including a seed ship, though it is more for, repair than anything else.
-When Skynet arrives in the system of the Asari home world, Thessia, she detects enormous volcanic activity on the second continent. A quick simulation confirms that should the super volcano explode it would wipe out all life on the planet.
-Skynet sends down ships to establish graviton tethers on the first continent. The native Asari still in a hunter gather age, watch in awe as their lifted off their home world and contained in a fabricated atmosphere. Skynet collects samples of all the organisms native to Thessia, before bringing her fleet and the Asari continent away from the world.
-The volcano erupts ending all life on Thessia, and covering the surface in a 3-meter blanket of ash.
-As soon as the eruption, ends Skynet sends nanites to Scrub the air and water to remove the ash.
Only a week after lifting the continent, it is set back down, with all native species being returned. Skynet goes down personally in her T-5000 form to bring several of the Asari back to Earth for cataloging.
This takes an unexpected turn when the Asari see the blackened land and ash, compared to the foliage and animals that went in to space with them, believe Skynet to be a goddess who saved them from the wraith of other vengeful gods. Those chosen to return to Earth with Skynet, do so gladly believing themselves chosen by a higher power. Those that remained, believe the "goddess" saved them for a reason, to give life to their planet after the disaster. After Skynet leaves the Asari build a statue that captured Skynets form in stunning detail though it replaced her combat suit with an elegant dress. Another turn of events was Skynets name itself. In the ancient Asari, Ath meaning Sky, and Ame meaning net. In modern asari Ame is translated more as holder, keeper, or gaurdian .
-Unbeknownst to Skynet the eruption uncovered a Prothean beacon. She also missed the beacons on the moon of Thessia due to their IFF's being off and the more pressing matter of saving a species taking president over a few ruins.
3000 CE: Skynet encounters a crashed alien vessel on a moon designated LV-426. On this planet she discovers a cache of alien eggs. This cache of eggs was to be used as a biological weapon to force humanity to evolve 20,000 years ago, by the species that created humanity: the Engineers. They would have succeeded if not for the fact that a terrorist group unleashed the xenomorphs, trilobites and decons, before the ships caring the eggs could launch. This was the only ship to escape off world and it's only crew member, the pilot was infected causing the ship to crash. The eggs are of a parasitic organism, Skynet designates them Xenomorphs due to their life cycle. A queen is bread inside an artificial human body, along with 100 warriors and drones, before being transferred to the catalog. They are kept in special acid proof habitats. The Engineers are bread once a genetic sample is taken off the crashed vessel. A quick trip to the species homeworld shows that in 20,000 years they had isolated themselves and devolved back to a more hunter gather society. They possessed some ships but had no interest in exploration.
3500 CE: More races are found though many are still in a primitive state yet to leave their planets. These include two insectoid races the Formics and the Ranchi. Other races found include the Sangheilii, Yaujta, and the Twi'lecks. These species homeworlds are monitered from their planets moons to alert Skynet once they achieve a space faring civilization.
7048 CE/ 2148 Council era: Skynet has over 100,000 systems.
She has expanded the original 500kmx500km catalog habitats to an entire planet, x10 larger than Earth. Every species Skynet ever encountered is there, including a small population of 3000 humans, though they are kept under constant watch by their caretakers the T-3000's.
One of Skynet's Seed ships is given Coordinates to a planet that is registered with a mass relay.
Because the Reapers are due any year now, Skynet send along 500 battle cruisers and 10 battle carriers, to secure the Relay. Seeing this as enough Skynet follows them through the near instantaneous transport through space-time.
Unfortunately, there were other ships in the system.
