Gaia IV is a planet, a class M planet and the fourth planet in the Gamma Quadrant's Gaia system. The planet is surrounded by an unusual energy barrier which includes a temporal anomaly.
History
In 2373, the crew of the Federation starship USS Defiant visited the planet and discovered that it was home to eight thousand inhabitants. The inhabitants were in actuality the descendants of the Defiant crew, in a timeline in which the starship was sent back in time to the 22nd century when it encountered the temporal anomaly upon attempting to leave the energy barrier. The inhabitants were erased from existence when the Odo who lived on the planet changed the course of the Defiant to avoid the temporal anomaly. The crew of the Defiant retained their memory of the inhabitants of Gaia IV. (DS9 episode: "Children of Time")
Starfleet later ordered a quarantine of the planet due to the energy barrier and the temporal anomaly. (ST reference: Star Charts)
Gariff Lucsly of the Federation Department of Temporal Investigations thought the causal loop experience by the crew of the Defiant at Gaia IV was one example of how conscientious the Deep Space 9 crew were towards the timestream. (ST novel: Watching the Clock)
