When Worlds Collide: A Story About Worlds Making History
This is a storytelling experience-- a story about what a magical perspective might call "other worlds" or maybe "other planes" and which science might call "other dimensions." (For simplicity, these rules will use the term "worlds.")
The worlds in question might be magical, super-scientific, or neither... But in this story, there's going to be more than one, and they're going to come into contact with each other, and that's going to make history in each world.
This is a story about writing that history.
By answering some simple questions, you will make a world, and then you'll name and describe a sentient being. That sentient being will then find (or, really, it will find them) an object that will open a portal to another world. Sooner or later, persons and things will start using the portal to travel from one world to the other... You'll start adding things to the story. A story mechanic is in place that will cause conflict (and solutions) to be added to the story... Gods, cosmic beings, heroes and villains and dangers will be added, and will affect the story...
As time goes on, the GM (the Guy who's Moderating) will open more portals, leading to other worlds...
Come write the the history of what happens when worlds meet...
