Planet whose civil war and fallen hero General Ardelon Tandro lay behind the attempt to extradite Jadzia Dax.
Klaestron IV is the homeworld of the Tandro family. During a civil war there, General Ardelon Tandro was killed after a coded message revealed his location to the rebels, and his death turned him into a celebrated hero of his people. Curzon Dax had been on the planet at the time, and suspicion fell on him.
In Dax, Ardelon's son Ilon comes to Deep Space Nine to take Jadzia back to Klaestron IV for trial. The hearing reveals that the general had actually sent the message himself in an attempt to betray his own side, a secret his widow Enina keeps from their world.
