Star of The Guardians

Star of the Guardians is a series of four science fiction / space opera novels written by Margaret Weis without assistance from usual co-author Tracy Hickman. The original trilogy, The Lost King, King's Test and King's Sacrifice, concerns Dion's adventures and eventual rise to the throne. A few years later, Margaret Weis realized that, while Dion had achieved his goals, the main characters of the series (sundered lovers Sagan and Maigrey) had not achieved peace, and penned the fourth book, Ghost Legion. She has since completed a trilogy of spin-offs concerning the mercenary team Mag Force 7 introduced in King's Sacrifice.
