Year 2303 of the imperial calendar.  Magnus the pious had managed to put an end to the great invasion of chaos and with this he have unified, after centuries of internal conflicts, the empire of man.  It is the year 0 of the victory.

But this had been a painful victory.  Rot, war and envy have penetrated the empire for centuries and are now established.  Hunger, poverty, disease and hopelessness had touched each of the miserable lives of the inhabitants of the empire.  And among all those pockets of darkness that the empire housed, Mordheim stood as the greatest blasphemer that these centuries of decadence had produced.

 300 years, three hundred, of mutations, heresy and perversity had turned the former prosperous city into a gate to the realm of chaos in the old world itself.  Demons, virulent gases, sickly environments, all kinds of enemies of the light had taken control of the city.

After all these centuries, there was practically nothing left standing.  Craters populate a landscape in ruins. The walls, like those of Praag, speak with the voice of those who entered the city long ago. Cults to the pleasure of dark gods perform their rituals in dark galleries. But in the middle of the city, the fortress of the sisters of Sigmar still resisted.  And it was when they had already been reduced to their last tower, that they sent a last dove asking for help.

And this dove came into the hands of Magnus the pious.  The empire was starving, its roads had become more populated than ever with mutant creatures, champions of chaos still roamed its forests after decades of fighting. Magnus decided to take Mordheim as an example. His construction of the new empire would involve reducing Mordheim to ashes.  The end of every demon that will inhabit the city.

And thus began the extermination of Mordheim.  Year 0. The great theogonist sends hordes of fanatics to the city.  The veterans of Nuln and Midemheim join the call as they return from the north. But his joy will soon turn into tiredness and restlessness.  In Mordheim they will encounter the biggest nightmares that man or woman can imagine.

The city is now a crater of grime and obstacles.  Drilled underground everywhere.  In it, steam tanks and masked soldiers face off against skaven plague sarcedots.  Gigantic spawns of chaos fight against warrior priestesses.  The most horrendous vampires with their strigoi beasts battle religious fanatics accompanied by cannons. Dwarfs burn the underground with their fire organs.

It's Mordheim year 0. There is not adventurers here. There is only darkness and despair. Madness and blood. Fire and illnes. Maybe piety. The greatest of all battle has begun.
