So there is a great channel on the OSR Discord server called #dice-democracy where you can crowdsource random tables. 

Therefore, this isn't 100% my work; the people on the server are very creative when it comes to stuff like this. I'm very grateful for them putting up with my ideas for tables. 

This is by far my favorite table that I started, tho.
