Unwritten: Adventures in the Ages of Myst and Beyond features a fantastic set of tools for creating Ages: alternate realities and worlds featuring unique natural resources, a single altered physical law of reality, or some ingenious, steampunk-inspired piece of esoteric machinery worth exploring. Like so many Fate-based games, there’s a great discussion of creating these sorts of worlds and translating them into location Aspects.
What follows is a stab at expanding the Age creation system, with an aim at providing more specific locations and conflicts to be explored. Additionally, there is a simplified framework from which improv-lovers can develop semi-randomized Ages. Players get a chance to really shine in defining Aspects of an Age, or using the Deduction rules to add details and variety to an existing Age.
