Space. The final frontier.
Here is where true adventure awaits, where danger ever lurks, and future is formed on every day, and every lightyear... or several.
Traveling makes up a good part of any decent campaign, and to travel is most natural in space - all three dimensions (or more) are open for exploration, attack, and escape. This is a scroll for the encounters in this environment, usually while the heroes are in a spaceship. Please add your own.
