The Diasporex was a nomadic civilisation of humans and aliens who lived aboard a vast collection of starships, maintaining a network of hydrogen collector space stations around various stars to fuel their vessels' power generators. They had been prowling the depths of space since the Age of Strife and their lifestyle may have evolved as a reaction to the horrors of that time on many human-settled worlds. During the last days of the Great Crusade in the early 31st Millennium, the Iron Hands Legion encountered the fleets of the Diasporex.
