Here is a possible template for a Guidebook page about a specific location in Interstellar Space, which is to say, not on Earth Prime, but in the Earth Prime universe. This is merely a suggestion, not a rule. You can use any part of it, all of it, or add your own ideas to it. To use it in its entirety, merely copy and paste it to an editor window in the appropriate Guidebook chapter.
(Place Name)
(Give a brief summary of the place here, including a general location in Known or Unknown Space, a short description of what it is like, and why it is significant in the Freedom City: Play by Post universe. If the place is of special significance to one or more PCs, note that here.)
Location and Appearance
(Give a more detailed description of where your place is located, whose territory of space, what constellation or galaxy, what solar system, whichever is applicable, and whether it is near any other notable places. If your place is a planet, discuss its population centers and land distribution, its climate and technological development. If it is a space station or other constructed location, describe its layout and technological development.)
Significance
(Explain why this place is an important place in Freedom City: Play by Post, in an IC manner. Does it have connections to Freedom City and Earth Prime, or is it more tied to the activities of spacegoing heroes? Does a hero come from this place, or did some major event happen here? Give information that tells why a character would go to this place, or why a thread might be set there.)
People
(Many locations have PCs or NPCs associated with them who might be encountered on a visit to this place. Make an unordered list to tell about the people whom one might encounter at this place. If your place is a planet, city or space station, describe the population.)
History
(Describe important events that have happened in this place. This can be just a paragraph for some locations, in other locations a timeline might be appropriate (see the Character Page template for information on making timelines)
