Yarka Yarka was a Bajoran and member of the Vedek Assembly until the year 2371 . According to official record , Yarka was defrocked for " teachings not in keeping with the Bajoran faith .

In 2371 , two months after Yarka was defrocked , several Cardassian scientists came to the Bajoran sector in an attempt to establish permanent communications to the Gamma Quadrant through the Bajoran wormhole . Yarka became convinced that Trakor ' s Third Prophecy was coming true and that the Celestial Temple would be destroyed . He urged Commander Benjamin Sisko not to assist the Cardassians in this venture , though Sisko ultimately chose not to follow Yarka ' s warnings . After the wormhole was not destroyed , Yarka concluded that he had misinterpreted the prophecy and apologized to Sisko for allowing his mistrust of the Cardassians to blind him to the Prophet s ' will . He did , however , add that there were signs that Trakor ' s Fourth Prophecy would soon come to pass . ( ) Appendices . Background information .

Tears start running down your face , your make - up starts to smear and then you can ' t get through your lines . No one thinks it ' s funny and you know that . Nina Craft was my makeup woman for this episode , and she got me going in - between takes . At one point it was one o ' clock in the morning and the two of us were just laughing like silly schoolgirls . The director then said , ' Places everyone , ' and I thought to myself , ' OK , I ' ve got to straighten up . ' I had this long , wordy scene that I was supposed to be very serious in . It was about doom and gloom and prophecies to come , and all I remember is just praying that I would keep a straight face through the take . So that was a fun episode . " " Apocrypha .
