Lief was born in the forest of Terabithia, where he and his nineteen siblings grew up, exploring and living their lives to the fullest.  He, Ariadne, and their sister Otere, were extremely close until one night when their father, Feofan, went out.  He never returned.  The family slowly started falling apart, with Ariadne fighting more and more with their mother and Otere becoming enclosed in a depressed shell, hardly talking at all.  Their other siblings also started growing distant from each other.  Lief tried playing peacemaker between their mother and Ariadne, but failed constantly.  One morning, their mother was nowhere to be seen.  It was a blow to them all, but they decided to stay in their old home, and try to pull themselves together.  That is where Ewan found them.  Ewan was immediately taken by Ariadne, and took her as a wife.  Of course, Lief and the others came along with her.  Ewan quickly grew accustomed to his new Andorian army, and with Ariadne by his side, began using them with full force.  Lief soon became one of his top assassins.  Lief grew to hate his new master, wishing for some way to get rid of him.  That way came in the form of Jake.  With Jake's help, the Andorians were rid of Ewan.  However, whenever Jake was being sent home to his own timeline and dimension, Lief was also sucked into the portal and found himself in a whole new world.  He has started courting Windy, but is reluctant to perform the Andorian binding ritual, called Oomox.  He doesn't understand many of the Humanoid ways, but with Jake, Windy, and the Phoenix Fighter Ariadne's help, he is slowly starting to settle in his new home.
