actually the Necros Mechanicum was created by the Ancients of Zol. The Ancients are similar to the Eldar, in terms of technological grasping and age of their race.
Here's the timeline, as it currently stands:
537 AD- Ancients of Zol civilization rises

2009 AD- same human male obtains an aging merchant vessel, outfits it with weapons; names it the Dreamrunner.
2022 AD- same human male is appointed the Lord Vraxedes of the planet of Vraxedais (VRAKS-UH-DAY-IS)
2033 AD- The Vraxedais planet has become the capital planet of an empire- the Vraxedes Empire has been born
2035 AD- capital relocated to the newly colonized, and currently terraforming Red Planet- Mars
2037 AD- March: Earth expedition to Mars provokes a possible conflict with the Empire, due to it's Treaty of the Mars Founding; August: ~10,000 Vraxeden civilian colonists on the Moon are killed by nuclear weapons fired from the surface of Earth. It is unknown what country fired the weapons. The Empire declares war upon the nations of Earth.
2038 AD- The Peace Treaty of Empire is signed, war ends between the USA, Russia, the EU, China, and the Empire. Catastrophic damages to Earth's infrastructure and mass losses of productive lands prompts the Empire to send aid to the people of Earth.
2311 AD- the 1st Lord Vraxedes dies at the age of 318. His 1st-born son succeeds him. The Empire continues to prosper. All of the 1st Lord Vraxedes' descendants are long-lived, reaching an average age of 290-310 years old.
2948 AD- 1st negotiative contact with the Ancients of Zol. Previous contact had been in brief meetings, consisting mostly of warnings.
3392 AD- The Empire declares war on the Neo-Sanguist (SANE-GWIST) Confederacy (NSC). At the same time, they also denounce the practices of the resurging Cult of Sikanu (SEE-CON-OOH). The Cultists ally themselves with the NSC. The First Age of Strife has begun.
3587 AD- after nearly 200 years of war, the Empire defeats the Confederacy. The Cult of Sikanu's primary temples and HQs have been destroyed. The Ancients of Zol arrive again, foretelling the Empire that it will not fall, but will fade into obscurity. The 1st Age of Strife ends.
3599 AD- the Halcyon Era of the Vraxedes Empire begins. It continues for ~8000 yrs.
4756 AD- the Necros Mechanicum splits with the Ancients of Zol. The Mechanicum is now led by the sentient robot Erasmus. They form a peace treaty with the Ancients.
5688 AD- the beginnings of the Empire of Taun'Shas have been laid, they begin to advance rapidly.
9822 AD- the Empire of Taun'Shas have an encounter with a splinter fleet of the Cretacus Necronum. Seven planets are lost, and are subsequently sterilized to contain the threat. This lays the foundation for the Taun's hatred of the Necronum.
11,607 AD- the Halcyon Era comes to an abrupt close when several planets of the Empire are attacked, the populations massacred. An alien race, the Noids, comes forth, arrogantly proclaiming that they have perpetrated the act. The seeds for the beginnings of the 2nd Age of Strife have been laid.
11,646 AD- After nearly 40 years of quiet, several Excelsior Starbases are destroyed. Nova MSFs are prepared for deployment. The Empire's enemies have struck again.
11,649 AD- the 2nd Age of Strife begins. The Noids have allied themselves with the Gorgols, while the Empire has no allies, as the Galactic Republic is refusing to enter into the conflict.
11,694 AD- The Galactic Republic collapses, from internal strife due to the numerous wars that are erupting, and external pressure from the Noids.
12,587 AD- after nearly a millenia of war, the ultimate act of destruction is approved by the current Lord Vraxedes. The Annihilatus Protocol is established. The first target is the Noids. Multiple Nova MSFs are deployed. The first Noid worlds fall. The Noid homeworld is destroyed, all life being exterminated and the planet cracked open at the core, rendering it down to a debris field.
12,686 AD- after an additional 100 years of fighting, the Noids have been exterminated. New empires have arisen, and are censoring the Vraxedes Empire for its drastic actions. The Empire closes its borders completely. No trade goes on except for internal economy action. People begin to forget about the Empire.
13,764 AD- after more than a thousand years of relative peace, the Empire of Taun'Shas arrives into the territories of the middle Milky Way. With highly advanced technology, they easily conquer several weaker empires in the locality. The Vraxedes Empire sends emissaries to the Empire of Taun'Shas. Negotiations begin.
13,779 AD- after 15 years of negotiating, the Vraxedes Empire and Empire of Taun'Shas sign the Treaty of Twin Empires. They agree to respect each others territories and come to each others aid if needed.
15,466 AD- the beginnings of the 3rd Age of Strife are seeded with the arrival of the coldly logical and rational Eggrenians. Their empire has expanded from a nearby galaxy into the Milky Way. The Empire of Taun'Shas declares war upon the Eggrenians.
15,538 AD- the Vraxedes Empire officially declares war upon the Eggrenians. They have been mostly rendering aid to the Taun'Shas and making guerilla strikes into Eggrenian territory until this point. The Eggrenians reveal their true numbers, which are among the quadrillions. This is compared against the billions of the Vraxedes and Taun'Shas.
15,539 AD- historians mark the year 15,539 AD as the official beginning of the 3rd Age of Strife. In all reality, it had begun a year earlier.
22,742 AD- the 3rd Age of Strife ends. The Eggrenians have been driven out of the Milky Way. Settlers wishing for more peaceful settings begin to depart in masses. They will eventually found the Trade Order, and later, the Trader Emergency Coalition.
22,749 AD- the Vraxedes Empire begins to fade away, as the Ancients of Zol predicted. War has tired the civilian populations that were absorbed/colonized for the Empire. Vraxeden-descent people feel that this is not the end.
23,448 AD- due to overpopulation, a failing economy, and other issues, the Eggrenian Empire collapses from internal strife
24,893 AD- the Empire of Egron Rising is established from the ashes of the Eggrenian Empire
27,443 AD- the correct date of the rise of the Xyphos Hegemony. Little is know except that they are expansionist and desire to control the universe.
39,876 AD- Mass revolts in core Taun'Shas worlds lead to more extensive rebellions among the Empire of Taun'Shas. They request aid of the Vraxedes Empire, but the Vraxedens are unable to give it. Relations become tense, and are eventually terminated between the empires.
40,706 AD- the Vraxedes Empire has decayed away completely. In its place is the Legion of Vraxedes. The remaining Taun leave the Milky Way.
41,007 AD- Mars is destroyed by a hedonistic and whim-driven empire, the Sanguinus (SANE-GWENE-US) Empire of vampiric beings. The Legion brings its wrath down upon the Sanguinus Empire, destroying several of its worlds. The 4th Age of Strife begins.
41,098 AD- the first encounters with the Necros Mechanicum. They are robots created by the Ancients of Zol many millenia earlier.
41,101 AD- The core worlds of the Vasari Empire fall silent. The Vasari Exodus Fleet begins its trek through space.
43,744 AD- the 4th Age of Strife ends. A small fleet of people from the Legion leave; the meet an equally sized fleet of Taun, and combine their ships.
43,745 AD- the small fleets that had combined a year earlier stumble upon an enclave of Anatolin and Forerunners. Negotiations begin between them.
43,746 AD- the negotiations end in the creation of the Explorator Republic of Mars Rising. Named after the now-destroyed capital of the Vraxedes Empire, the Republic is notable for its powerful Mars Legacy Battlecruisers.
43,853 AD- Vraxedais falls to siege. The whim-driven empires that have arisen in the wake of 4th Age of Strife sieze its multiple natural resources, that have been carefully shepherded and preserved by the Vraxedens, and consume them in the course of 10 years. Historians give this as the date that the Xyphos Hegemony rises. The Xyphos Hegemony had actually arisen several millenia earlier.
44,709 AD- universal censorship by the other empires of the Milky Way motivates the Legion to construct grand Explorator fleets, much like the fleets of the old Empire. They begin their way out of the Milky Way. Their advanced Inter-Dimensional travel allows them to rapidly leave the areas they once inhabited. They are further motivated by a need to survive.
48,866 AD- the Trade Order is founded.
50,104 AD- the predecessors of the Advent are expelled from their homeworld by the Trade Order. The Ancients of Zol are surrepticiously observing the Traders, Psionics, and the Vasari. They wait for the next Age of Strife to begin.
51,104 AD- the Vasari Exodus Fleet arrives in Trader territory, quickly brushing aside what little defenses there are. The Trader Emergency Coalition is founded to combat the xenos threat.
51,114 AD- the Advent returns to the Trade Order's territories, creating a 2-front war for the TEC.
51,119 AD- a 15 year war has been waging between three powers, the TEC, Advent, and the Vasari Exodus Fleet.
51,120 AD- the Legion and Taun'Shas arrive in Trader territory. They begin to wage war with the other races, and renew the Treaty of Twin Empires between themselves. The Explorator Republic also arrives. Learning of its origins, the Legion and the Taun'Shas decline the petition of the Republic to be added to the Treaty of Twin Empires, and instead offer a new treaty between the three, the Treaty of Triumvirate. It is signed and passed into law for all three empires.
51,122 AD- continuing negotitians with the TEC sees the TEC petition to be added to the Treaty of Twin Empires. The Legion and Taun'Shas will likely reject this request, but will not immediately announce this to the TEC. This is especially true as the Treaty of Twin Empires has been replaced by the Treaty of Triumvirate.
51,123 AD- the Xyphos Hegemony, in its quest to dominate the entire universe, arrives into the local galaxy. Numerous worlds begin to fall silent as the Xyphos people, known as the 'Xatians' take control of world after world.
51,124 AD- the Sanguinis Empire, and the Empire of Egron Rising arrive in the local clusters. The Ancients of Zol declare the 5th Age of Strife to have begun. Mass warfare erupts among the stars, bathing the galaxy in blood.
51,125 AD- six months after the Ancients of Zol declared the 5th Age of Strife to have begun, extensive contact with the Necros Mechanicum occurs. The Cretacus Necronum arrives in the system, and multiple worlds fall off the grid. They have been devoured.
