First up… Space Sharks ! From the Lexicanum: The Space Sharks Space Marine chapter took part in the Badab War against the rebel chapters. After the defeat of the rebellion, they were given the homeworld of the rebellious Mantis Warriors . In the war, the Space Sharks used their longstanding tactic of Drop Pod assaults in their attacks on the hives of Badab . The large number of dreadnoughts , and their full reserve of Terminator Armour were used to help the Star Phantoms ‘ sieges of the rebellious Chapters. The Space Sharks still to this day carry a long standing grudge and distrust of the Mantis Warriors and the Lamenters . Let me know what you think.
