Mysticora is a fantasy e-mail game of epic scale with both role-playing and strategic elements. It is designed to be a universal system in the sense that it can be played with a variety of scenarios. These will usually be fantasy worlds with ancient to late medieval cultures covering the area of a small continent (e.g. Europe) and lasting up to a decade of simulated time (though being potentially open-ended). The games will be challenging to players in complexity of rules, sheer size of the game world, and story depth. It is therefore better suited for the veteran player willing to get deeply involved, than for the casual or novice player.The player will slip into the role of playing a multitude of game world persons simultaneously. In effect a groups of persons dedicated to a leader (the main character) or the cause that he or she represents. These persons will be heroes defeating terrible monsters, commanders leading fierce armies to battle, rulers caring for the welfare of their subjects, arcane masters delving deeply into the workings of magic, and many more. Therefore, a player's position may include anything from the single hero to an empire spanning the length of the known world.
There is no common goal that players need to achieve, such as military conquest. Instead, players will themselves determine what they will strive for, be it even only traveling around and exploring.
