Shattered Worlds

March 15, 2041

Dinosaurs Ravage Las Vegas Strip!

Witnesses have described three days of terror as hundreds of “dinosaurs” ran amok through the Las Vegas Strip, killing 16 people, wounding 302, and leaving 751 reported missing. Federal authorities have closed off the neighborhood and brought the situation under control using the U.S. Army and Nevada National Guard.

An unnamed government source told this reporter that the creatures originated from a six-acre jungle that had “appeared out of thin air” in a nearby housing development. What happened to the people who lived there has authorities baffled.

Shattered Worlds

Technology and magic collide on a broken Earth.

Fractures tore open the barriers between worlds, exchanging vast pieces of Earth with alien landscapes and carrying plants, animals, and entire peoples into unfamiliar realities. When new Fractures connected Earth to the Abyss, invading demon armies brought a war fought with magic and nuclear fire. Civilization collapsed, billions died, and the devastation became known as the Fall.

Twenty-five years later, the climate is recovering and survivors are venturing beyond their protected communities to rebuild. Across the shattered landscape, humans, elves, orcs, devils, liches, and other displaced peoples compete for safety, resources, and power. Player characters form professional teams that take dangerous missions, explore the unknown, and decide which factions will become allies, enemies—or both.

In Development

Shattered Worlds Reforged

A rebuilt edition powered by Basic Roleplaying and the Siegebreaker BRP engine.

Reforged brings Shattered Worlds into a flexible percentile system built for dangerous expeditions, hard professional choices, surviving technology, scarce resources, and magic in a world remade by the Fractures and the Fall.

More character possibilities

Expanded species and new or revised professions create characters with distinct backgrounds, capabilities, and practical roles within a professional team.

Tools for a shattered world

Expanded equipment covers weapons, armor, survival gear, modern technology, rare pre-Fall discoveries, and the difficult choices created by limited supplies.

Magic with a cost

Setting-driven magic brings together Soul Points, spells, Otherworldly Patrons, Warlocks, and Eldritch Invocations. Magic is powerful, scarce, disruptive, and never taken for granted.

The Siegebreaker BRP engine

Percentile skills, tactical combat, wounds, fatigue, sanity, meaningful consequences, and episodic campaign tools support missions that grow into larger story and season arcs.

The planned launch line includes a Player Guide, a Game Master Guide, and a launch adventure. A Kickstarter campaign will follow once the core books are substantially complete and ready for production.

Shattered Worlds Player Guide cover

Build a team and take the jobs that keep civilization alive.

Reality fractured, pieces of other worlds replaced parts of Earth, and magic returned alongside surviving technology. Communities endure behind defended borders while professional teams travel into the dangerous spaces between them.

Characters may be soldiers, scientists, pilots, explorers, mystics, and specialists brought together by contracts that demand more than any one profession can provide.

The original 5e line

The first edition established Shattered Worlds through core books, encounter supplements, and a full road-campaign collection. Explore the complete published line below.
