Shallan had been Ba'al's lo'taur, his most trusted servant, until she betrayed her master and assisted Kanan, a Tok'ra operative, to gain access to Ba'al's secret facility. She fell in love with Kanan, but when he returned in the host body of O'Neill to rescue her, both were captured, and O'Neill was tortured after Kanan fled the body. O'Neill rescued Shallan when he made his escape, and she chose to remain with the Tok'ra and continue to fight in Kanan's name.
