On January 10 2408, as the first Human colonisation vessel, the Nova Maria, boarded its passengers for launch, tragedy struck. A Hiver nesting fleet, consisting of a Dreadnought and several support vessels, arrived in the Human race’s home system. The planetary defenses of the Human race, which had never before encountered another star–faring species, were negligible and easily brushed aside by superior Hiver firepower. The Nova Maria was destroyed in the first volley with all hands lost and the Human home world was bombarded from space for 48 hours afterward, resulting in massive devastation and catastrophic loss of life.
Only the legacy of Humankind's suicidal past eventually saved their home world from complete destruction. After nearly 36 hours of struggle, the curators of the planet's former ICBM arsenal finally managed to reactivate their remaining stock of ancient missiles which had been stored for decommission in the silos of the North American and Asian continents. A total of 3,000 fission and fusion bombs were launched at the descending Hiver fleet, destroying its full complement of Destroyers and causing serious damage to its Dreadnought.
Thereafter, the remains of the Hiver fleet left orbit and limped on.
As a result of this devastating first contact, Humanity proceeded to treat every Hiver subsequently encountered with extreme hostility, resulting in the Hiver War.
