text: Catalyst's demon invasion is set in our world and during our time. You are not fighting on another planet; you are battling in your country. Instead of trekking through the Elf Forest, you are fleeing Denver through the Rocky Mountains looking for safe haven.
  Your group's favorite bar becomes the resistance's meeting point and the ornate church down the street is the headquarters of a demon-worshiping cult. The magic brought by the demons blends with the technology of modern humanity; survive in your city however you can.
