Medusa V was a Mining World of the Imperium of Man that was devoured by a Warp Storm in the year 999.M41. Luckily, the military forces of the Imperium were able to evacuate the entire surviving civilian population of the planet before it was consumed. Before completing this evacuation, the world became the center of a large military conflict between eight of the Eastern Fringes of the Milky Way Galaxy's major powers for control of the world, each for its own reasons. This military action became known as the Fall of Medusa V in Imperial records.
