Hello! Glad to see you're taking an interest in the Fiction Universe. To put an article in the Fiction namespace, simply append "Fiction:" to the beginning of the article's title, such as with Fiction:Manitja Illuminated Singularity. I also recommend using the page creation options listed under "Create a Page" on the wiki's homepage.

As for article-improvement tips, I recommend listing important information under various sections and subsections, such as History, Government, Society, Technology, Military, etc. Don't be afraid to take cues from other users' pages regarding formatting. I recommend checking out some of the more completed pages made by users such as Cyrannian, Shiznasty, and Methanogen; all of them have pretty well-developed and well-organized articles (though I'm not saying many others don't, of course).

A lot of us can be reached at a variety of times on the wiki's Discord server, so feel free to pop in there and ask questions as well.
