Oblivion Event

The Oblivion Event is what has come to be known as the time when the Overlords invaded the Chaos Mundus on June 15, 2564. The event lasted until March 3, 2569 when the Superplanet was revealed to the people of the Chaos Mundus.
The Overlords made first contact with Humans on Earth on June 15, 2564. While no one on Earth could see the massive fleet above them, the presence of them was undeniable. They spoke to everyone, in a thousand languages, many of them long dead, including binary and morse code. They informed them that transports would be arriving shortly to allow them on board their World Ships. Having already been warned of this possibility by Draconus, the nations of the Earth relented. They informed their people not to resist. 
While the majority of the planet quietly boarded the vessels, there are records of skirmishes between certain Humans and the Overlord soldiers who arrived alongside their dropships. These people were immediately put down. They gave the Humans of Earth one week to gather their belongings and climb aboard the World Ships. At the end of the one week, Earth was consumed by the World Ships - every bit of dust absorbed within the hull of the fleet. The rest of the Sol System fell shortly afterwards. 
The Overlords went on to other systems, consuming them as fast as they had Earth. A great many species were spared the vicious wrath of the Overlords due to the warning from Draconus. However, either ignoring Draconus' warning, or having never heard it, certain species like the Lekgolo fought back against the Overlords and were quickly and mercilessly decimated. 
Between 2564 and 2569, half of the entire Chaos Mundus had been consumed by the fleets of the Overlords. On March 3, 2569, the Superplanet was complete enough to house the confused masses of the citizens of the Chaos Mundus.
