Ulic Qel-Droma spent years learning to control the Force. He wanted to be on the side of the good, a member of the Jedi elite. But it is not the Force one must control to become a Jedi; rather, one must learn to control oneself. Ulic Qel-Droma has tasted power, and now he cannot fight the dark hunger inside him . . .
5000 years before ANH. Note that this places this series chronologically before the rest of the Tales of the Jedi series, despite being the 5th volume according to date of publication. It also, therefore, has the distinction of being the earliest story yet told in the Star Wars universe's chronology.
