From the publisher's website: Expand your HardNova 2 adventures with the Intercosm. Explore a galaxy-spanning empire with this alternate setting. The Darhren Empire is populated by thousands of different races living on thousands of different worlds, but designed for flexibility and accommodation for a wide range of play, from street-level adventures to epic quests that change the face of the entire galaxy. Gamemasters can run stories entirely within the Intercosm, or easily link it to the United Sovereign Worlds setting provided with HardNova 2.
