Seskal was a Cardassian officer who joined the Cardassian Rebellion in 2375. After Kira Nerys proposed attacking a weapons depot on Adarak Prime, Seskal was incredulous that she would suggest attacking a target protected by a Cardassian garrison. Later, Seskal and Rusot tried to irk Kira by bringing up the fact that Odo had worked for the Cardassians on Terok Nor during the Occupation. (DS9: "When It Rains...")
