I have a bunch of tables and generators, but it's all in Portuguese on my Brazilian blog Pontos de Experiência. I am mainly working on my Adventurers of the Lost World setting book, but I will eventually translate some of my stuff in English to post here, which is exactly what this post is about today.
When running my games I always want to give the feeling of a world in constant motion and change. The characters can start in a settlement, go on an adventure and when they come back, something must have happened. The world continues without them, and they have to notice it somehow. This will give them the impression that the campaign world is real, even when they are not around!
To aid me in this task, I came up with this simple d30 table. It gives you a general idea you can interpret and create more elaborate events in pretty much any kind of settlement. So, whenever you feel like enough time has passed and some sort of change should happen to a place in your campaign world, roll on the table below and adjust the result to the settlement in question!
