Cyrah Endal was Prentice Endal's wife. They have a son, Wylie Endal. Cyrah faded away after Prentice's mind was broken, after a light leaping incident. She has a tree in the Wanderling Woods with violet/blue flowers and reddish leaves due to the fact that she had violet/blue eyes and reddish hair.
In Lodestar, it shows that she was actually nearly murdered before light leaping, throwing off her concentration. When she is found after light leaping she is gone beyond anyone's repair.
