Fire Scorpions

The Fire Scorpions are a fleet based chapter of Imperial Space Marines. Created as a successor chapter of the Dark Angels specifically to hunt The Fallen far from the main fleet of the Unforgiven. They mostly roam the Octavia Sub-sector, where the majority of their recruiting worlds are located. There's a large number of Death Worlds within the Sub-sector, plagued with horrific warp spawn and diseases of Nurgle. The harsh conditions and feudal traditions make it an ideal location for them to recruit. Two-Fifths of the chapter is Primaris as the chapter was present when Demonic forces attacked The Rock and lost 40% of their number, later making up those losses when Guilliman arrived and gave the Unforgiven their new Primaris Brothers.

Fleet
The fleet of the Fire Scorpions is rather large for a typical Space Marine Chapter, but this is mostly a result of the Chapter’s fleet based nature; the fleet serves as their home. The Fire Scorpions have 7 Battle Barges, 4 of these are not to Codex Astartes specifications, specialized instead for space engagements. Each of these non-standard Barges has a nova cannon and multiple torpedo bays, forgoing the large carrier bays a typical battle barge would have. Along these capital ships are 20 Strike Cruisers and numerous smaller escort craft.
