Karana was a Klingon concubine who lived outside the Imperial Stables during "The Dark Time".
When the Third Dynasty came to power, Karana was given the name and title of Shenara, daughter of Emperor Reclaw, in an effort to make it appear as though the imperial family's lineage remained unbroken. Karana was Sirella's 23rd maternal grandmother. (DS9: "You Are Cordially Invited")
