Midgard

This science-fiction setting presents a garden world with an Earth-like environment and a supercontinent encircling its mid-latitudes. Although the planet supports human settlement, its society is troubled by a native virus, offworld political divisions, and an illegal weapons trade. The book provides planetary and system information, history, government, technology, and society, along with guidance for creating characters from the world. It also includes a planetary map and information suitable for Cepheus Engine and OSRPG campaigns.
