The Void-Lions chapter geneseed is Imperial Fist in Origin, which makes the Imperial Fist Successors. However, due to the conditions on their homeworld, Zulup IX, most of the Zulupians are dark skinned, and keep this trait as Astartes, bearing no semblance to their Primarch-Progenitor. This mixed with the fact that they only recruit from the Zulupian Tribal population explains their complexion. They- however- have inherited Dorns genetic disposition and darkness of stoic seriousness, unwillingness to surrender. and even deep depression.

Imperial Records say that the Void Lions were founded during the 23rd or Sentinel Founding. In actuality, they were created during the 21st or Cursed founding. Their Geneseed was tampered with by the Adeptus Mechanicus and is one of the reasons why they suffer from what they call the Gene-curse of Zulup; Gigantism that strikes as a marine gets older, conflicting with his geneseed, making him immobile and eventually killing him. Those who survive the curse become giants, even for Astartes standards.
