Break the Horizon
This supplement expands travel across the Ninth World, where isolated communities and vast distances separate explorers from the secrets of prior worlds. It provides mounts, ordinary and numenera vehicles, travel-focused cyphers, artifacts, equipment, and an index of travel options from other Numenera products. It also includes creatures and NPCs, travel-themed GM intrusions, hazards, encounters, advice from experienced travelers, and two adventures that can take place during a journey or at its destination.
