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. Based originally on The Magnificent Seven, the team developed a much more varied membership just in time to star in their own novels: The Knights of the Black Earth, Robot Blues, and Hung Out. Weis and Don Perrin released a collectible card game under the name "Mag Force 7". The Lost King Seventeen-year-old Dion Starfire has lived on a backwater planet, Syrac 7, with Platus Morianna for his entire life, but that life is about to turn upside down as Sagan has finally found them. Platus contacts Mendaharin "Tusk" Tusca, the son of an old friend, and pays him to take Dion off-planet. Platus himself stays behind and buys time with his life. Tusk and Dion travel to the planet Vangelis to seek the advice of General John Dixter. Sagan, for his part, manages to track down Maigrey Morianna who has also been off-radar for seventeen years. The fact that they were once lovers does not stop him from arresting her as a monarchist and sending her to trial. Sagan then travels to Vangelis to help put down the rebellion (i.e., Dixter's forces). Dion goes voluntarily to the Warlord's flagship, where Sagan and Maigrey informed him of his true heritage. The novel is punctuated by an attack from the Corasians, an alien race bent on conquering our galaxy. King's Test Though Dixter's mercenaries fought honorably beside Sagan's forces to repel the Corasians, Sagan orders them killed at the end of The Lost King; at the beginning of King's Test, which picks up moments after, Dion sallies out to save his friends. He flees with Tusk and Nola (Tusk's new girlfriend), though Dixter was captured. Maigrey leaves as well, traveling to the nauseous planet of Laskar, where a weapons magnate named Snaga Ohme has been building a new weapon. This space-rotation bomb,
