The only thing the players know about the story is the title, but soon they're right in the middle of it. The gamemaster begins by describing how a subspace experiment aboard the Farragut has gone terribly wrong. A starfish-shaped creature the size of a large dog has crawled out of the experiment and is chewing on a power conduit. To his surprise, the creature isn't there when he shoots it. The situation rapidly gets worse.
More creatures blink into existence and spread throughout the starship.
As the gamemaster ratchets up the tension, describing how the lights are failing and the computers are shorting out, the players make desperate suggestions to each other for stopping the creatures. Playing the roles of their characters, they observe the creatures, try out possible solutions and occasionally run for their lives. After an hour of play, the players understand what they're up against. Then one of the players has an idea. At the beginning of the session a routine sensor scan turned up a nearby black hole.
