"We have known storms such as this -- they raged when our Chapter was raised, on Mars the Red, and to them we owe our name -- we are the lightning bringers. Such tempests hold no fear for the Fulminators."
The Fulminators are a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines, created from the lineage of the vaunted Ultramarines and raised during the Ultima Founding of ca. 999.M41.
The Fulminators were one of the first Primaris Space Marine Chapters to be founded, raised in the early days of the 31st Millennium even as the last battles of the Great Scouring were still being fought.
The Aspirants selected were the best recruits heading into the Terran Guard, and they have been in stasis beneath the surface of Mars for nearly 8,000 standard years until awakened for the Ultima Founding by Archmagos Dominus Belisarius Cawl.
The Chapter was named for the electrical storms that rage over Mars, which at the time of their creation were the worst seen in millennia.
The Fulminators have joined the other Ultima Founding Chapters in reinforcing the Imperial war effort of the Indomitus Crusade.
