Mentor Peet Sieben was a philosopher who lived during the Clone Wars in 22 BBY. Sieben was a member of the Jal Shey, an ancient order of the Force-sensitive dedicated to studying the Force as a solely intellectual endeavor. Sieben believed that war was a terrible thing but acknowledged that it brought out great qualities in people. However, Sieben wished conflict did not have to be such a critical catalyst for those traits to emerge.
