Duvalle was a human-occupied world colonized during The Scattering, and one of the first attacked during the final plan to exterminate human-kind by Omnius and the reborn Thinking Machine Empire, during the advent of Kralizec. With the planets Ronto and Pital; Duvalle first experienced what would be Omnius's plan to wipe out humanity. Send probes seeded with the dreaded Omnius Scourge to planet first, almost wiping out the population of the world. Then the survivors would be barely able to defend the world against the Thinking Machine's million-starship space Armada.
