Dominion Rules is the rules system for a very popular type of RPG: a fantasy RPG. Fantasy RPGs take place in mediaeval, mythological settings such as King Arthur's Britain or the Middle Earth of JRR Tolkien's novels. Other RPGs take place in science fiction, gothic, and many other settings. Dominion Rules was created with fantasy RPGs in mind. But it is a readily adaptable system. You can create sci-fi, gothic, cyberpunk, and other versions of DR under the terms of the Dominion Rules License.
