From the introduction:
The adventure begins with the characters falsely accused and brought aboard the Eos Keldor, a battle cruiser of the Lorendi Imperium. At the beginning of the adventure, the Eos is sabotaged by a small group of spies belonging to the Valna Fleet. Each player character will have their own reasons for being on the Eos Keldor. Throughout the scenario, the players will need to work together to escape the Eos while it is engaged in battle with the enemy. There are no escape pods on the Eos. The only way for the players to escape the cruiser is to steal the Lorendi shuttle stationed in the docking bay.
