The Guardians – Threat Of Extinction begins with a Lataran Guardianship leaving their home planet on a mission to investigate a report that one of their protector planets had been attacked by a new enemy alien race called the Tyrax who have invaded their star systems. First Commander Òmon is in charge of the Guardianship named Poltara. What Òmon finds on the mission is abhorrent to his species.

The Tyrax would not negotiate for peace. They seemed intent upon eliminating any race they discovered to take control of the planet for themselves. This act of extreme annihilation could not be tolerated and the Latarans were now at war with the Tyrax. Not only were the Tyrax determined to destroy the Lataran people, they used a new terraforming weapon on every world they attacked to make it suitable for their species. Something about the Tyrax required the need for a different type of world than was currently present for their survival. Òmon was determined to find out just what the reason for this was.

Later, Òmon was given a new mission by his superior commander. He was ordered to journey to a new star system to protect it from the Tyrax before it was discovered. The reason for this was unusual. It seemed the race in this star system called Sol was another warrior-like species. They fight each other to the point of extinction of the losing race. He must recruit them to fight on Lataran Guardianships and Starfighters if they hope to win the war against the Tyrax.

Supreme Master Commander Galis is the leader of the Tyrax Empire located in the Canis Major Dwarf Galaxy in the constellation Canis Major 42,000 light-years from the Galactic Center of the Milky Way galaxy. Their dwarf galaxy was in the process of being torn apart by the gravitational forces of the Milky Way galaxy. First Commander Eto is given a special assignment to test a new Doomsday weapon that can be used to terraform whole planets in a matter of days. He is assigned a new mission to use the weapon on the star system called Sol.

This is a Novella Prequel story that introduces several main characters and situations that follow in The Guardians Series. Book 1 begins when the Tyrax attack Earth and send a Doomsday weapon that detonates multiple missile warheads over twenty-four sparsely inhabited land areas around the globe. It causes a biological transformation using nanobots that threaten to destroy all life forms on the planet within days. Only the Lataran Guardian Òmon can help save Earth from extinction. Book 2 continues the story when the Tyrax return to finish the job with a a new weapon they call the Destroyer, a large asteroid that will do more damage to the biosphere than the meteorite that wiped out the dinosaurs sixty-five million years ago. In Book 3, the Tyrax are building a large particle accelerator to create an antimatter weapon to use against Earth. The first opponent to build the weapon will win this Galactic Space War between good and evil alien races.
