Synopsis:
The time is ten years after the Sith War. Exar Kun has been trapped in his Massassi temple. His chief lieutenant, Ulic Qel-Droma, was stripped of his powers by Nomi Sunrider, after he killed his brother Cay. Ulic has isolated himself, he wishes only to hide from the Republic, and hope history will forget what he's done.
Guilt-ridden, Ulic Qel-Droma hides from his past on the frozen world of Rhen Var. Meanwhile, on Exis station, Nomi Sunrider calls together the Jedi Knights to discuss the future of the Republic. After hearing so much about Ulic and remembering him from her childhood, Vima Sunrider decides to go in search of him. When Hoggon discovers Vima on his ship, he is astounded to learn that the mysterious stranger he took to Rhen Var is in fact Ulic himself.
Vima Sunrider finally meets Ulic Qel-Droma, and instead of reminding the once-great Jedi of his glorious past, Vima is only a grim reminder of the power he once commanded and can never hold again!
On Rhen Var, the powerless, exiled Jedi Ulic Qel-Droma continues to train Vima. Sylvar, the ferocious Cathar Jedi, has gone into isolation herself, directing all her anger and energy toward thoughts of revenge aimed at Ulic. But when a messenger comes to her campfire, informing her that Vima Sunrider has vanished, she rushes to offer Nomi any help she can give.
Nomi Sunrider travels to Rhen Var to find her daughter training with Ulic Qel-Droma. She tries to take Vima away but sees that she needs to make her own decisions. Sylvar also arrives on Rhen Var seeking to kill Ulic for killing her mate. But while fighting Ulic she comes to understand that she needs to move beyond her anger over her mate's death.
