"The Demon Lord is dead. The kingdom survived. So why does everything feel worse?"



Welcome to Modern Aetheria.

Five hundred years have passed since the age of the Demon Tower.

The Demon Lord was defeated.

The great heroes of old became legends.

The world endured.

Yet peace proved far more complicated than victory.

Aetheria has entered a new era of prosperity, progress, and unrest. Trade flourishes, cities expand, and technology slowly emerges alongside ancient magic. But beneath the surface, corruption festers, wealth gathers in noble hands, and the gap between rulers and commoners grows wider every year.

The people no longer fear demons.

They fear their own kingdom.

And in this changing world, your story begins.

Who Are You?

You are you.

An Outworlder who arrived in Aetheria years ago and rose through the ranks of the Royal Troops during the Great Aetherian War. You fought on the front lines. You survived battles that became history. You earned the trust of kings, generals, and soldiers alike. When the Demon Lord reached its peak once more, you stood among the heroes responsible for ending the war and securing Aetheria's victory.

For a time, your name was respected across the kingdom.

Then everything changed.

As corruption spread through the monarchy, you openly criticized the crown and sided with the people. In response, the kingdom accused you of plotting regicide, stripped you of your rank, erased your honors, and exiled you from all royal grounds. To some, you remain a hero. To others, a traitor. Most only know the rumors.

Now, one week after your exile, you return to the Adventurer's Guild—the same place where your journey began. Without a title. Without authority. Without an army. Just an adventurer once again.

What happens next is up to you.


The World of Modern Aetheria

Aetheria remains a realm parallel to Earth where Outworlders continue to arrive from distant worlds and forgotten lives.

Magic still exists.

Monsters still roam.

Ancient ruins still hide treasures and dangers alike.

But the greatest threats are no longer always found in dungeons.

Some wear crowns.

Some wear uniforms.

Some hide behind laws.

For the first time in centuries, the future of Aetheria may be decided not by a war against darkness, but by the choices of its people.

(Creator's Note: Aetheria if shit gets real. Its been near 2 years since i released Aetheria universe, suddenly i found a surge of motivation to create a sequel to it. This time, it'll be livelier, there's more NPCs, more prota and antagonists. I highly recommend playing with background musics like Golden Brown, or anything medieval related alongside the roleplay. Enough said, please enjoy, and leave ratings and comments!)
