Caprius Seaton, prince of the country of Elysium on the planet Alamptria, just wants to lead a simple life. He does not want to become an agent on the council of Confidus, who is his father, the king. But according to an ancient prophecy, Caprius and a woman named Melina Hampshire will have a son named Lantrinon who will destroy the dark lord Makoor, whose goncool and vampire forces have begun trying to kill Caprius. Though they were once lovers, Caprius and Melina separated when she was seduced and betrayed by Capriuss friend, Fenison Torington. Now, six years later, Melinas mother is being manipulated by Makoor to oppose the reunion of the two young people. When the woman dies, the way is opened for the two lovers to reunite and fulfill the prophecy. Because no evidence of the supernatural nature of his attackers remains, his father is convinced that the neighboring country of Bramonia is responsible for the numerous atrocities. While on a motorbike holiday, Caprius is attacked by teams of goncools and vampires, who capture a train on which Melina Hampshire is riding, killing everyone except her and rigging it to explode when it pulls into the depot. However, the elf wizard Grongone intervenes from afar and enables Caprius to rescue Melina and destroy the train with all the vampires and goncoolsonce again eliminating all evidence of the existence of vampires and Makoor. Despite his sons claims, King Confidus plans to attack the neighboring country in three days. Caprius experiences a series of visions that confirm that wizard Grongone has selected the Seaton family to save the planet of Alamptria from the forces of the underworld. On his own, Caprius makes his way to Serenity River, which forms the border, where he evades a huge nest of vampires. In Bramonia, Caprius meets with the soldier Brandimoir, the brother-in-law of Melinas sister, Selena, and convinces him that he wants to stop the pending war between their two countries. Convinced of Capriuss claims by a vampire that his soldiers kill, Brandimoir sends a courier with the creatures head to King Confidus as evidence. Caprius meets up with a human agent named Shelly Hathoway who accompanies him in his air shuttle to Crimson Peak, where the vampires and goncools have their base. The pair fly the shuttle into the heart of the underworld forces subterranean lair, where thousands of vampires and goncools are preparing to overwhelm the world. Allowing himself to be captured, Caprius triggers a timed explosion within the vampires stolen space capsule and escapes with Shelly, though he has been wounded. The pair escape as the GRIM lair is destroyed, but so does Samuel Trenton. Returned to Castle Elysium, Capricus recovers and is reunited with Melina. He is now a fully-fledged knight master committed to fulfilling his destiny as the father of the man who will deliver Alamptria from the dark dangers that are coming.
