The Star Scorpions was a Loyalist Space Marine Chapter of the 25th Founding of unknown origin. They are now considered extinct, a lost Chapter of Astartes. It is unknown what Chapter provided the gene-seed for the Star Scorpions' Founding and little else about the Chapter is available in Imperial records.

Chapter HistoryEdit


Star Scorpions Chapter Colour Scheme

Death of the Star ScorpionsEdit

The Star Scorpions had the dual misfortune of producing highly mutated gene-seed and being utterly devastated by daemonic entities when the Chapter's fleet became trapped in the Warp. The exact fate of the Star Scorpions is unknown. However, the High Lords of Terra decreed on behalf of the Emperor of Mankind that the Chapter should be considered irrevocably lost when the Adeptus Mechanicus proved incapable of using their corrupted gene-seed to reconstitute the Chapter.

Reallocation of Chapter NumberEdit

The highly mutated gene-seed hampered Imperial efforts to rebuild the Star Scorpions Chapter and eventually the bio-engineers and chem-architects of the Adeptus Mechanicus were forced to concede defeat. For a time it seemed that the Chapter number 888 would never be used again, but some years later, with the 26th Founding of 738.M41 in the offing, the Mechanicus were persuaded to revisit the Chapter colours, number, and regalia, resulting in the creation of the Mentors Chapter. The Mentors received the colours and number of the extinct Chapter but instead of the Star Scorpions' corrupted gene-seed, they were provided with an entirely new generation of genetic material collected from the storage banks of the Mechanicus' Terran laboratories.

Chapter AppearanceEdit

The Star Scorpions used the same colour scheme as the current Mentors Chapter.

Chapter ColoursEdit

The Star Scorpions primarily wore forest green Power Armour which included the backpack, helm, shoulder pauldron trim, chest guard and groin. The shoulder pauldron insets, arms and leg armour were white. The Aquila or Imperialis on the chest guard was golden. The squad specialty symbol on the right shoulder pauldron was red.

Chapter BadgeEdit

The Star Scorpions' Chapter badge is not listed in current Imperial records.
