NERO is dedicated to the legendary days of high fantasy, while running a fun (and above all safe) game. In the NERO game, you create a character concept for a fantasy story and actually play the character. It is much like improvisational theater in that you have a framework created by the props and supporting characters and must develop your part as you progress through the storyline.

Your character's attitudes, ambitions, and history are yours to define. If the adventurous life is your calling, you may play the part of a wanderer, meeting with some friends in the tavern. While swapping tales, your party could get hired by a poor farmer in desperate straits, and spend the afternoon slaying a foul necromancer and his undead abominations.
