Orias

The Orias system was a star system in Cardassian space in the late 24th century.

In 2371 Starfleet Intelligence suspected a fleet of Cardassian vessels was secretly being built in the system. The Maquis feared this might be a build up to new attacks by the Cardassians so Thomas Riker stole the USS Defiant from Deep Space 9 to investigate. He was prevented from entering the system by a group of Keldon class vessels. (DS9 episode: )

Starfleet’s suspicions turned out to be accurate when it was later revealed a secret fleet was being build in the system by the Obsidian Order in a joint operation with the Tal Shiar to destroy the founders homeworld in the Gamma Quadrant. (DS9 episode: Improbable Cause)

In 2376 Kasidy Yates conducted a cargo run to the Orias system where she obtained a shipment of Rakalian p'losie. (DS9 novel: Avatar)
