21 The USS Olympia begins to return from its mission of exploration in the Beta Quadrant. As it turns back, the ship picks up some strange energy readings in a nearby star system. They divert to investigate, discovering an energy barrier surrounding a nearby planet. The ship scans the planet with active scanners, which triggers a quantum reaction that destroys the ship. Only the Captain, Lisa Cusak, survives.21

Cusak manages to attract the attention of the USS Defiant over subspace radio, and the Defiant rushes to save her. Unfortunately, the energy barrier around the planet time-shifts the communication some three years into the future, a fact not evident until the Defiant arrives at the planet in 2374. Unfortunately Cusak is long dead by this time.21
