I've been doing some writing in Obsidian and I really like it so far. I use these templates for plotting out some speculative fiction settings I've been thinking about in my head but have never committed to writing. These were adapted from aegontv's World Anvil style templates, so shoutout to them. I modified them to better fit my use case and work with the plugins I have. You can download them below:
I also use the following plugins and themes:
Infoboxes: Great if you want a Wikipedia-style infobox for your pages. My templates use syntax that rely on this template, so if you're going to use them make sure you have this plugin installed.
Image Gallery: Does exactly what it says on the tin. Very low-maintainence and works well out of the box.
