Deindum War

The Deindum War was a temporal conflict between the Deindum and the Coalition of Civilised Worlds in the Mutter's Spiral. (PROSE: Adorable Illusion)

Origins
Irving Braxiatel discovered that the Deindum were destined to eventually replace his people as the most advanced time-travelling species in the universe. He decided on a plan to avert their creation before a conflict arose between his people and the Deindum. (PROSE: Present Danger) Braxiatel and Doggles attempted on several occasions to destroy the Deindum before they evolved into sentient creatures, but on each occasion they were stopped by Deindum from the future. (AUDIO: Escaping the Future)

The conflict
The Deindum first showed themselves to the universe on Maximediras. They shot down survivors who attempted to evacuate and established a prisoner of war camp on the planet. (PROSE: Present Danger)

Braxiatel destroyed a Deindum armada in the Battle of Capra. (PROSE: Winging It)

The Deindum tried to make Deimos and Phobos leave Mars' orbit in the 21st century. Merlin sent Excalibur to Winifred Bambera and Ancelyn in order for them to use the sword to prevent the Deindum's plan from succeeding. (PROSE: Excalibur of Mars)

Sixty-eight Grel were taken by the Deindum to work in the slave camps on Bastion. Rather than working in the pits with the other slaves, the Grel became food-servers and maintenance workers. (PROSE: Adorable Illusion)

Bernice Summerfield discovered that during the industrial age of the Deindum's development, they were contacted by Deindum from the future and were given time travel technology. Shortly after they gained the ability to travel in time, the Deindum's biology was altered by Braxiatel to make them a weaker species.

With time travel, the Deindum conquered the universe and wiped out the human race.

Because their appearance was different when the Deindum contacted their past, Bernice Summerfield and Braxiatel manipulated the situation to portray the future Deindum as con artists and a war broke out between the future and past Diendum. The war caused the Deindum to be destroyed at a point before they developed time travel and thus failed to conquer the universe. (AUDIO: Escaping the Future)

Rather than wiping the Deindum out entirely, Bernice Summerfield's actions reduced the Deindum from a set of ultra-savage warmongers to a small set of skirmishers. Some planets that were destroyed came back, although they didn't know they had been destroyed.

Most of the Deindum lost the will to fight, and the war was considered to pretty much won after the the Battle of the Pakhar Shipyards and later the Defence of the Tsarissian Drydocks. (PROSE: Adorable Illusion)

Legacy
After the War had ended, the Braxiatel Collection disappeared.

Both Bev Tarrant and Adrian Wall were hailed as war heroes, and led the United Worlds. Bernice Summerfield became well known due to her actions in the war, though it was widely believed that she had died in the conflict. (PROSE: Adorable Illusion)
