The people of Klaestron IV, allies of the Cardassians, who try to seize Jadzia Dax and try her for a murder supposedly committed by her previous host.
The Klaestrons appear in the Deep Space Nine episode Dax. Thirty years earlier their world was torn by civil war, during which General Ardelon Tandro was betrayed to the rebels and killed. He became a national hero. Curzon Dax, then a Federation mediator and a friend of the family, had no alibi.
In 2369 the general's son Ilon Tandro leads a team that tries to abduct Jadzia Dax from the station. Because Klaestron IV has an extradition treaty with the Federation but not with Bajor, Sisko forces a hearing before a Bajoran arbiter, which turns on whether a new Trill host answers for the acts of an old one.
Jadzia refuses to defend herself. The case ends when the general's widow Enina admits that Curzon was with her at the time of the betrayal and that her husband was himself the traitor.
