This is the official lore and mythological foundation of Devil of the Plague, a co-op medieval horror game set during the Middle Ages and inspired by ancient Sumerian mythology.
Before time was divided into calendars; when the names of the ancients were spoken with fear and blood… There was a name in the ancient Sumerian pantheon that was only whispered: Asag.
He was not a king that had any dominion.
Nor a guardian weighing humanity's fate with justice.
Asag was the child of chaos. The laughter of destruction, the breath of disease, the crack within order itself.
Asag was an Ancient Demon; he held no throne of power but a corrupting whisper that spread. And when he was expelled, he unleashed upon the world, rotting cities, poisoning waters, and planting fear within the hearts of men.
With his footsteps, the plague was born. With his breath, brother turned against brother.
Eventually, the time has come.
The divine will that guarded order imprisoned Asag in Purgatory, a bottomless abyss belonging neither to existence nor oblivion.
There, time did not flow.
Their screams did not echo.
But Asag was not silenced.
For tens of thousands of years, he continued whispering from that dark void.
His words seeped not into ears, but into minds.
Into those driven by ambition. Into those who are defied death. Into those who mistook darkness for knowledge.
When the medieval age arrived, and the world was shrouded in the fog of black magic
Sorcerers who dug beneath the earth, opened graves, and sealed forbidden books with blood…
they heard Asag's voice.
“Immortality,” said Asag.
“Power,” he promised.
“Strength beyond mortal limits…”
In return, he sought for only one thing: servants willing to act in his name.
Rituals were performed. Blood was spilled. The forbidden was invoked.
And once more, stepped onto the world.
With him came chaos.
Plagues. Wars. Kings driven mad.
Those who summoned him were rewarded becoming commanders in Asag's armies, drifting far from humanity.
But every time Asag was called forth, we were there.
We are an order that has existed for fifteen thousand years.
Founded by the will of the Great God, erased from history, our traces reduced to legend.
Chosen from among men, entrusted with what others are not.
Each of us carries a spark weak alone, unstoppable together.
We have defeated Asag many times.
Each time, we forced him back into Purgatory.
And yet we know: he never gives up.
We are in the era in which we will wage our greatest war against it, the "Middle Ages." It has reached all the important cities of the world; we will destroy it in the atmosphere of the Middle Ages... Today or tomorrow...
in the Medieval castles. In Egypt. In the shadows of Istanbul. In the great Asian palaces. On a pirate ship in the middle of the ocean...
Asag may rise again, but this time we will silence him forever.
And when the call comes wherever it comes from with our blades, our knowledge, and our loyalty to one another, we must find him and destroy him.
Because the world cannot endure its laughter once more.
