This is the definition of a one horse town.

And that horse lives over the town's one bathroom, powering its mechanisms while people stand in line.

This ancient Dwarven town once was famous for its healing baths. Now it's just known for the bad smell that emanates from it (as the line for the bathroom doesn't allow many people
to bathe regularly).

...or it was, before
​our heroes intervened!

Not a prince by royal blood (though they could be) The Merchant Prince is master over that which moves the world:

Recruit hirelings, make deals, grow a financial empire, and make Dungeon World your cash cow. ​Capitalism, Ho!

You once were like them, optimistic and blind. You were oblivious to the truth that lurked in the stars. Whether it was ambition, greed, or sheer luck, you somehow made contact with an incredible being from far beyond our ken. You were touched by it and filled with immense power...a power that threatens to drown the world in madness.
The Voidtouched is a playbook for Dungeon World, one that allows you to embrace (or combat) your darker side. The Voidtouched relies on fear, insanity, and horrific transformations to combat their foes.
When starting out, the Voidtouched can be frail, and their main source of power will be from changing themselves using Gift of the Stars. As they grow in power, however, they can craft homunculi from their enemies' shadows, scare others into obeying them, and even pave the way for their patron to enter this world! Prepare to grapple with powers beyond your imagining as you play the Voidtouched

Some people pray to their gods for strength like fools; others, too smart for their own good, read books. Others, still, train with their sword-arms or their tongues. Not you, though. Somehow, somewhy,
you found power through another way, one wrought in fire and pain. You made a sacrifice, then and there, freely given, for powers beyond the ken
of mere mortals.

And it feels so, so good.

You’re the wildcard now. The uncaged flame, burning with passion and leaving ruin in your wake. Everyone else can feel it, too; your fire stokes theirs, filling your new adventuring comrades with furore and  frightening the lives of every yokel and maiden lucky
enough to cross your path. You’ve never felt so alive! And so what if there’s trouble following you every which way; all the more reason to
live life to the fullest, right?

Live fast, die young, and make sure you’re not the one who’s gotta pick up all the pieces.

"Someone heard a noise?" asked the guard to his companions.
Too late, you thought.
While your shadow clones kill the other guards, you put a kunai on the man's throat. "Tell me where the scroll is and your death won't be painful."
This playbook let you play a Shinobi, an oriental warrior trained in the magical arts on Ninjutsu.
Inspired by various popular manga and anime,
​this is a playbook for Dungeon World.

Look. There, on the horizon. See that sun? It burns as hot as our hope. Its light has travelled all this way just to shine on us, and them, and the whole world. So wipe the blood from your face and know that whatever barriers stand in our way, we will overcome them. Because even if we die, our dreams never will. Our hope will last eternal, blazing hot and bright and glorious for a billion years. Little by little, the lives we touch and the lives that those lives touch will make the world brighter and brighter and brighter, until the whole world's hopes twinkle and shine like the stars in the sky.
Believe in me. Believe in us. With hope on our sleeves and love in our hearts, we cannot be steered wrong. We will make the cosmos.

The Dungeon World version comes with twenty all new advanced moves to determine
​your Princess's destiny.

Short answer: Dungeon World is a Fantasy RPG that's Powered by the Apocalypse.

Slightly longer answer: The main thing that sets games "Powered by the Apocalypse" are structured differently than most RPGs on the market. Instead of having a designated setting set in stone, or maps already drawn, or long backstories or details all planned out, Dungeon World provides some basic resources and lets the players and Dungeon Master (or DM) fill in the gaps.

Did you choose to play The Wizard? Well, there's no one quite like you and your mastery of magic. There can't be another Wizard quite like you - you're The Wizard of the story, and everyone else wishes they were so important.

Did you choose to play The Paladin and set out on a Quest to "Slay Amarakto the Cruel, a great blight on the land"? Well, you and the rest of the people playing the game with you are going to have Amarakto the Cruel as some sort of antagonist.

The whole point is to Draw Maps, But Leave Blanks and Play To Find Out What Happens​.
