In an alternate reality, the Delta Coalition was an alliance of Delta Quadrant species. Existing between the years 2375 and 2376, the Coalition included such species as the Vostigye, Voth, Vidiians, Nezu, Nyrians, Tarkan, Hirogen and the crew of the USS Voyager who had been stranded in the Delta Quadrant due to a devastating attack by Species 8472. The Coalition was created due to the renewed attacks by Species 8472, and the efforts of the Voyager crew.
In 2376, the Coalition developed a device which increased the barrier between fluidic space and their universe, and any other reality threatened by Species 8472.
Also in 2376, the Coalition received permission to use the Hirogen communications network, and, utilizing a new holoconferening technology, was able to make direct contact with the United Federation of Planets. Member worlds of the Delta Coalition then petitioned the Federation for membership. (Myriad Universes novel: Places of Exile)
