World List 

Here is a list of concepts you can use for your adventure. These are a starting point. Feel free to takes them and modify them however you like.

Knights of Antarctica
The Sun is dying. As the core heats up and gets denser, the Sun grows in size and turns from a brilliant white to a shade of red. Back on Earth, the atmosphere has turned hot-house. The equatorial regions are now scorched and unihabitable. Only the poles can sustain life. Antarctica holds the last vestigese of civilization. Reduced to a simple feudal society, brutal kingdoms vie for domianance on a dying world. But there is an ancient blueprint for a machine with the promise of escape. Can the kingdoms be convinced to stop their petty squabling and pool their resources to build this machine?

Sea Peoples Lost
The Bronze Age ended in a climate crisis. The Middle East grew hotter and crops failed. Cities could no longer sustain themselves and starved. Refugees known as the ‘sea peoples’ spread across the Mediterranean seeking to plunder the dying civilizations and establish new homes. A large flotila having plundered the wealth of Egypt, crossed the Straight of Gibarltar and was swept by a storm across the Atlantic. The Sea Peoples must now face the Olmec.

Yellowstone Wasteland
The American railways were expanding West. The new lands were filled with gold miners and the blue coated cavalry that protected them from the Indian tribes. But then the greatest volcano on earth errupted at Yellowstone, belching out soot and lava and turning the skies over Boston and New York into a hellish red and black. North America is now a wasteland, a lost continent. But where most see ruin, there are a few who see opportunity. Could a tyrant pull the flag out of the ash?

Deep City
The Russians and Americans went to war and the surface was destroyed. A large underwater submarine base in the Siberian Actic became a haven for humanity. Refugees from the nearby town filled its halls and chambers before being sealed in. Fast forward a hundred years and the base is now a city. Exploring the city, you will find endless labyrinths of twisting halls, huge caverns filled with towers and monorails, promonades with domes looking up from the ocean floor to the phosphoresent fish above... Deep City is a communist paradise. Or at least that’s what the Chairman believes.

Mongol America
A tsunami smashes the Mongol fleet as it tries to invade Japan. One of the ships is blown across the Pacific. After a harrowing journey, it arrives in a new land. They find huge trees, heavy rains and tribes with terrifying masks. The Mongols are told if they follow a great river over the mountains, they will find a flat plain as vast as an ocean. Could this be a homeland for a new Khanate?

Vampires of the Somme
The English are preparing for the great Battle of the Somme. But a terrifying squadron of German pilots has moved into the region. These pilots are part of a secret society of vampires. At night, they land behind enemy lines and stalk the English soldiers.

Beast of Stalingrad
The Nazis developed a serum that turns soldiers into savage beasts. Crates of this serum are airlifted into the Stalingrad pocket during the final days of the seige. The starving soldiers must decide whether to take the serum and live like animals, or freeze to death in their holes.

Frozen Earth
A small black hole passed through the solar system disrupting the orbits of the inner planets. Mercury and Venus plummeted into the sun. Mars was thrown into an eliptical orbit. The Earth was shot out towards deep space. It has been 45 years since the event and each year the earth has grown colder. Neptune can be seen next to the moon in the night sky. The oceans have frozen and the atmosphere is a thin liquid, boiling against the void of space and can be navigated by boat. Survivors live deep underground, mining the heat of the Earth’s mantle. Going to the surface to scavenge requires thick makeshift spacesuits. Gangs fight other over territory.

Jihad of Doom
The Kaaba in Mecca is an ancient alien relic. It activates during a Medieval Hajj turning everyone walking around the object into super soldiers.

Project Gliese
The Japanese launch a great project to open a wormhole between Tokyo and a planet in the Gliese solar system. But when the AI camputing the immense calculations is denied the power it needs, it turns on its human masters.
