Few regiments of the Militarum Tempestus have achieved greater honours in war, and their deeds typify the obedience, excellence, and efficiency for which they are known. It was the 55th Kappic Eagles who boarded the Ork scrapship Scarfist and destroyed it, saving the Valtlax System. The 55th Kappic Eagles aided the Space Wolves of Erik Morkai’s Great Company against Word Bearers upon Fellbrek III. These elite Militarum Tempestus soldiers were responsible for crippling the Crimson Slaughter strike force upon the Ybrekian Ice Worlds, and led the destruction of a traitor filled hive city upon the Vorrul Shrine World. When the legendary Ordo Tempestus relics, the Barbed Gauntlets of Avitus, had been stolen by Eldar from Craftworld Altansar, the Scions of the 55th Kappic Eagles were summoned to retrieve them. With vengeful purpose, the Eagles smashed through wave upon wave of Guardians in order to reclaim them.
