The Midnight City are a once reclusive industrial empire, founded long ago in the Age of Myth around the slumbering form of a Goddess. Every cog, every steam tunnel, every artisan clockwork mechanism in the city was engineered to channel the powers of the Realm to restore their Goddess from her Age long slumber, it was these need to innovate, need to create new methods of pulling more power from the very air around them that spurred the cities industry. The contracts they garnered through such innovation when into funding new research into Cog and Steamwork technologies to revive their ward.
It was however only as the Age of Chaos dawned that the Goddess awoke, her first breath was said to be the cities last. Every cog froze, every steam tunnel suddenly grew empty, not a sound of the clockwork was to be heard throughout the City. In the first days of the cities death those who only sought to exploit it for wealth abandoned their holdings, fleeing to the safety of Azyr and the riches it might offer their coffers, as days turned into weeks then too did those whose hearts were conflicted, buckling to the need for safety over their love of the city they had dared to call home. Finally came the Heirs of the noble houses, each great house dispatching one heir to Azyr that their lineage might not die with the city they could not bear to leave, it was as these heirs crested the mountain range to the south of the city that they looked back to see their homes ablaze, a piercing beacon of ruin benearth the darkened sky.
When the Heirs reached Azyr they spoke of the death of Midnight, a tale cemented by all those who came before them but made all the more real by their description of the flames that claimed the city. As her lie was cemented in the minds of the Azyrite host, and all who might carry rumour out into the greater realms, the Goddess and her remaining loyal populace continued their labours in the hidden under-workshops of the city. It had been they, in the Goddesses eternal wisdom who put flame to all that remained above the streets of the old city, returning the land to the wilds and shadow daemons that any encroaching forces would see little but the gutted husk of the City that once was.
With this lie in place, and the populace reduced to number sustainable in the Undercity, comprised of only those with the resolve and vision to see through the plan of their Goddess the innovations of Midnight have continued through the Ages. The Undercity now spreads beneath much of the mountain ranges surrounding the old town, far larger than the husk from which it has risen once more, they produce Cogwork mechanisms the likes of which few others could dare to replicate.
As the Age of Sigmar dawned the Midnight City rose phoenix like from the ashes, though hidden they had maintained smuggling routes with local tribes to ferry arms and supplies where needed yet with Azyr open and the seeds of hope growing a new market had been born for their innovations of war. The goddess however remained elsuive, now masquerading as the Midnight Queen those who traded with her city would never have seen even a hint of the divine, a genius in no doubt but mortal.
All this has changed with Lethis, unwilling to see another stand alone against the darkened tides the Midnight Host marched forth, the queen resplendant at the head of her cities armies, at the apex of the battle however her true form was unmasked and face revealed to the hosts Azyrite. And now the city lays besieged, the the Azyrite host demanding the Goddess return to the Penumbral jail she once occupied, her populace unwilling to yield she who staved off the darkness and allowed them to prosper.
A city alone,
The City of Midnight
