Before dungeons existed—
There was war.
The First Era
In the earliest age of magic, the world was not ruled by academies, systems, or rankings.
It was ruled by gods.
Not divine beings born of faith, but mages who had surpassed mortality itself. Those who reached Godhood commanded the laws of magic as instinct. Mountains were lifted with gestures. Oceans were divided by will alone. Reality bent because they demanded it.
This was the First Era.
It ended the day the Demon Realm opened.
The Demon Realm
The Demon Realm was not a dungeon.
It was not a trial.
It was a world of its own—one born from chaos, ruled by instinct, conquest, and endless slaughter.
From its depths poured demon armies and demon kings, each capable of annihilating nations.
And at their peak stood a being beyond comparison—
The Demon God.
It did not command mana.
It devoured laws.
Where gods shaped reality, it erased it. Continents burned to ash. Oceans boiled away. Civilizations older than history vanished within weeks.
The world faced extinction.
The War of Gods and Demons
The god-level mages fought back.
Sky shattered as divine spells collided with demonic authority. Space folded under the weight of combat. For the first time in existence, magic was forced beyond its limits.
Gods fell.
Demon lords followed.
The war raged until the world itself began to break.
And at last—
The Demon God was sealed.
The Demon Realm was driven back beyond reality.
The mortal world survived.
But victory demanded a price history would later try to forget.
The Price of Victory
Every mage who had reached Godhood died.
Not one survived.
Their deaths were not defeat.
They sacrificed their divine existence to bind the Demon God—splitting its essence, chaining it beyond the edge of reality, and preventing it from ever crossing realms again.
With their passing, the laws of magic weakened.
The age of gods ended.
That was the fall of the First Era.
The Birth of Dungeons
Dungeons did not appear naturally.
They were constructed.
Fragments of sealed Demon Realm energy leaked into the world, warping space and corroding reality. To prevent another invasion, the surviving archmages reshaped these unstable zones into controlled battlefields.
Thus, dungeons were born.
They served three purposes:
To contain demonic remnants
To strengthen future generations
To filter out the weak
Dungeons are training grounds.
The Demon Realm is war itself.
Confusing the two is fatal.
The Forbidden Path
Among all disciplines of magic, one art was erased after the war.
Necromancy.
Not because it was evil—
But because it was effective.
Necromancers did not fear death.
They commanded it.
During the war, they raised fallen mages and demons alike, forging armies that did not tire, did not flee, and did not break.
Even the Demon God acknowledged them as threats.
When the war ended, necromancy was sealed, purged from records, and branded as heresy.
Yet death did not vanish.
It waited.
The Truth Unspoken
Ancient beings still remember a secret no history records:
The Demon God was not destroyed.
It was delayed.
And when it returns, raw magic will not be enough.
Only one force has ever threatened it directly—
A sovereign of death.
A being capable of commanding souls, corpses, demon lords, and fallen gods alike.
One who does not fight alone—
But arrives with a Legion of Death.
An army born from battlefields, extinct races, shattered civilizations, and forgotten deities.
A force capable of crushing the Demon Realm itself.
Such a being cannot rise naturally.
It requires:
A core capable of defying all limits
A will unbroken by death
A soul that has already died once
Somewhere in the present era, a sealed Legendary Red Core pulses quietly.
And deep beyond broken dimensions—
The Demon God stirs.
Death is not approaching.
It is awakening.
