"A long, long time ago, in a Galaxy far, far away..." -Star Wars opening scroll
"This is a highly disturbing universe" -Maggie Simpson, Tree-house of Horror V
"Well, sir, if things are real, they're there all the time."
"Are they?" -The Lion, the Witch, and the Wardrobe
One would assume that any given universe would be subject to the same laws. After all, no set of laws would be very useful if not always self-consistent, and what applies to one situation applies to another. One would simply be making a reasonable assumption.
Sadly, one would be badly mistaken...
For in an unknown part of the cosmos lie a collection of star systems, connected to each other by a network of stargates; natural space-time anomalies that can transport people to far-off destinations. And each system has its own set of rules.
This thread will be done in the fashion of the original Idaho; everyone will create the complete setting and people of one inhabitable world around a single star. It will be up to you to provide the physics, magic, and technology if present, provided it doesn't powergame. Orbital colonies and the like will be allowed provided that your people have the ability to set them up. You will design your worlds and their "technology" as you see fit. You can even have magic star-ships that have breathable air bubbles. The physics governing magic and technology are not canceled by traversing from system to system to allow interaction and warfare.
Interstellar travel is available only by way of the Gates, giant space-time wormholes in a known location of each system. This is done to prevent sudden "warping" to areas vital to other players and proceeding with wholesale looting and slaughter of an exposed side.
This is a placeholder, so expect some editing in future.
