In a world where a cataclysmic event has destroyed the ability for people to route between major settlements without getting lost, ending up where they came from, or being utterly desecrated in mind and body, a select caste of people - ‘Navigators’ - have become the only remaining links between pockets of civilisation, able to depart from one city and arrive at another, completing the journey to their intended destination. 

A select few of the select few have been able to charter their journeys and make rudimentary maps - ‘Cartography’ has become a type of pseudo-magic skill, the maps making travel possible for non-Navigators perhaps once or twice before the map loses its efficacy; but there are rumours of an Atlas, a definitive map, permanently effective that would allow humanity to guide itself across the globe once more.
