Brianna Withridge

From Smallville Wiki

Brianna Withridge was one of the comrades of Countess Margaret Isobel Thoreaux and a skilled witch. She was born sometime in the late 16th century and was killed in 1604 when Brianna, Isobel, and Madeline were captured by the townspeople and were sentenced to burn at the stake for practicing witchcraft. They lost their spell book and were burned at the stake in the courtyard.

Centuries later when Isobel awakened and possessed Lana to find the Stones of Power, she brought Brianna's spirit back and it was transferred into the body of Lois Lane. However when Clark arrived to stop the witches from getting the stone at the Kawatche Caves, he destroyed the spell book with his heat vision, and Brianna's spirit was removed from Lois's body.
