Dynamic Campaign System

Introduction and Cosmology Part 01

gaming rpg dnd dcs

This is the first part in a series, where we'll be talking about a concept for generating an entire campaign on-the-fly for your favorite fantasy role-playing game. In the future, it might have a tighter focus on either D&D or Pathfinder, but for now, let's consider this material more-or-less generic.

We have a couple of goals here for the Dynamic Campaign System (DCS) that are worth relating.

First off, this is a guide for the potential GM looking to create their own original campaign setting. It runs them through a series of steps and dice rolls, as well as some decisions based on personal preferences. When it's all finished, it should produce something unique and tailored to the sort of campaign setting the GM and players are looking for. Mostly it's a series of lists and tables. You can run through it all and make decisions as you go, or you can roll a die here and there (or everywhere!) and let fate decide how this world will look.

Secondly, it shouldn't take very long, start to finish. Creating an original campaign setting can be laborious and time consuming. Part of the purpose of this project is to speed that process up, and to make it less-painful, over all. Granted, creating a world can be lots of fun; imagining the structure of things, the societies, the history the races and all the major players. These can be incredibly exciting! DCS does NOT replace that process. Instead, it's meant to help you in it, because, let's face it: sometimes campaign construction can be a drag. Sometimes you're short on time, or the real world intrudes (Boo! Hiss!), and leaves you short on mental and creative resources for a time.

Thirdly, different parts of the world-build experience appeal to different people. Maybe you like creating your own gods and legendary heroes; you love conjuring up all their stories and myths, and plugging these in to your world in the form of religions, ancient temples, and dangerous relics from the past. Maybe these things are your meat and drink, while the layout of a world's land masses, seas, and climatic regions is hideously boring to you. If so, you can skip right over the DCS section on Cosmology, and jump right in to the section on World Construction. Is all THAT stuff fun, but you hate thinking about the politics of the world? Does the idea of laying out the structure and leadership of nations seem dull or intimidating? Then create all the gods, and all the lands and seas of your world, then turn to the DCS section on Nations and their Governments.

Fourth an finally, the goal of DCS is to inspire, not constrain. The tables and lists of this project are intended to spark your creativity when you need it the most. Maybe nothing in a particular section seems especially interesting to you; it might spark an idea, though. In the end, that may be the best way to use random tables for you: not to be slavish to the whims of dice, but rather, to wander across a series of ideas, laid out in an easy-to-read format, that might well get those creative juices flowing.

So without more preamble, let's look at the first entry in this series...Cosmology!

NOTE: Listed below are four tables that possess many elements, some of which describe other elements that as yet need fleshing out. The intention here is to create hooks that can inspire your own creativity, as well as ours. We intend to describe many of these elements in future tables, so if you find yourself frustrated by any incompleteness here, well, that's because it's incomplete.

NOTE: All the usual polyhedron dice are used for DCS, though today, we'll only be using 1d12.

01: Cosmology

01.01: What came before?

What existed before this world? Was it another world, filled with heroes? An endless plane of energy or thought? Or maybe there was nothing at all?

NOTE: All the usual polyhedron dice are used for DCS, though today, we'll only be using 1d20 and 1d12.

Roll on the following table, then consult the subtables below.


  1. Another world, like the one you are about to create.
