Tectonia Prime

Tectonia Prime is a planet located within the Tectonian Subsector of the Vlaktes Sector. Its location at the center of the Tectonian Throat, the most stable warp route into and out of the sector, made it a vital strongpoint for Imperial interests. It was the capital world of the sector from late M38 to 10.1 TPCM.M41, when it was assaulted by a combined force of the Archenemy and deposed.

Early Years
Originally known as Tectonatta, the planet now called Tectonia Prime was one of the seventeen Foundling Worlds of the Vlaktes Sector. Throughout most of its history, the planet's volcanic wastelands and general inhospitable nature made it a tertiary player in sector politics, a perpetual also-ran in a race dominated by the golden worlds of the Lothairian Marches, like then-capital world Amadacia.

It was only with a surge in the Mare which blocked off every other way into the sector circa 2000 previo TPCM.M41 (or M38 by the old reckoning) that the planet came to any prominence. This warp route, the Tectonian Throat, as it came to be called, was (and still is) the only clear way into and out of the Vlaktes Sector. As the sole inhabitable world in the system at the heart of the Throat, Tectonatta became a major seat of power. Changing its name to Tectonia to better reflect the suffix conventions of high Imperial society, the planet rapidly ascended in prominence, and by late M38, had deposed Amadacia as the capital world of the Vlaktes Sector.

The Fall
Main Article: The Fall of Tectonia Prime The Fall of Tectonia, or the Tectonian War, lasted from 10.1 to 11 post TPCM.M41. It was fought between the forces of the Archenemy and the Imperial defenders of Tectonia Prime. The war resulted in a victory for the Archenemy Host, the fall of Tectonia, the ascension of the planet as a daemon world of Chaos, and the severing of the Vlaktes Sector from the wider Imperium. It also heralded the opening of the broader Tectonian Front, which would consume most of the resources and manpower of the deeper Vlaktes Sector for years to come.

Tectonia Prime Today
Tectonia Prime, long the jewel in the Vlaktes crown, has fallen, its lands and cities riven by the fury of the Archenemy. Reports from the fall of Tectonia are conflicting at best. Astropathic cries from the system told of lance strikes upturning the volcanic landscape, of warriors in black and gold sacking the city of Asalhive, and of Varrendonk, the King Hive, turned to a morgue at the hands of an ancient virus bomb. Now, nothing at all comes from Tectonia Prime save the wailing of lost souls and the dread hosts of the damned.

With its fall, the sub-sector which bears its name has been overrun by calamity and warfare. The faces of this war are many--Militarum Traitorous, Heretic Astartes, and the unspeakable legions of the warp itself.
