Zero Legion

The Zero Legion is an Adeptus Astartes Chapter of unknown founding. There is very little information on them, and even that is sealed away deeply by the Inquisition. They have shown to possess numerous technologies and weaponry of the early days of the Imperium, thought loss during the Horus Heresy, as well as from the Dark Age of Technology and incredible Warp Technology too. Each member is also a Blank, having inherited the Pariah Gene somehow. They have also shown a deep grudge against not just the Chaos Space Marines of the Traitor Legion, but also the Ecclesiarchy, viewing the former as a threat to mankind, and the latter as a disease. Despite that, they appear to have a good relationship with the Adeptus Mechanicus, for their sharing of their technology with the Tech-Priest of Mars, and several Adeptus Astartes chapters, as well as strong resolve of the defense of humanity.
