A terminal Cardassian disease that brings the dissident Legate Tekeny Ghemor to Deep Space 9 to die in the company of Kira Nerys.
Yarim Fel Syndrome appears in the Deep Space Nine episode Ties of Blood and Water. Ghemor, who once believed Kira to be his lost daughter Iliana, arrives on the station already close to death; Bashir can ease his pain but cannot stop the illness.
Ghemor asks Kira to take part in the Cardassian rite of Shri-tal, in which the dying pass their secrets to their family for use against their enemies. She agrees and records what he tells her about the Cardassian government, now allied with the Dominion.
His decline stirs Kira's memories of leaving her own father's deathbed, and she abandons Ghemor when Dukat reveals his part in a wartime massacre. She returns in time to sit with him at the end and buries him on Bajor beside her father.
