Four hundred years ago a plague befell the world. It warped the bodies of all organic things and drove both man and beast rabid during the night. Law and order vanished in a matter of days, along with most of the human race.Years passed and from this madness rose the Tyrants, a brutal god-like sect of individuals who could enforce their will on the surviving dregs of humanity. With their tyranny, they brought order back into the world and established settlements. A convoluted semblance of civilization began, aided by the magic of Necromancy, to raise those butchered in the night, and Hemomancy, to heal their injuries.In Umbras, domain of the Tyrant Lock-And-Key, all humans are incarcerated at night where they cannot harm others or the city. Beyond that, Lock-And-Key does little to interfere with the lives of her subjects.However, this fragile balance is threatened. A usurper lurks in the steam-riddled Undercity of Umbras, plotting his ascension to godhood. More than that, a stranger arrives in Umbras at night–crossing through the tormented, plague-consumed wilds–seeking revenge on those who murdered his brother.
