Cyral Nine was a Cardassian woman, and an agent of the Aegis working within the Cardassian Union prior to the Dominion War. She sometimes had contact with the Federation's Department of Temporal Investigations.
In 2369, Cyral told the DTI to stop investigating the Devidians' time travel activities.
In 2370, Cyral worked with DTI agents Gariff Lucsly and Marion Dulmur to dispel a temporal distortion in the Hugora Nebula.
In 2381, Cyral again met agents Lucsly and Dulmur, but this time it was on Nivoch and Cyral had resigned her position with the Aegis because the Dominion War had destroyed all her work. (DTI novel: Watching the Clock)
