"‘The Storm Giants’ ways are ancient, though their origins are lost to the ravaging inferno of time. I witnessed their neophytes on Torquar being led in what their sergeant called the Doctrine of Ash, and felt a sliver of recognition. My old sergeant of the 7th was as patient and wise, and I knew then the strength of our allies."

— Brother Rheshhan, Salamanders 4th Company

The Storm Giants is a Loyalist Codex Astartes-compliant Chapter of Space Marines created during an unknown Founding. Its origins remain unknown, though many savants suspect that it is a Successor Chapter of the Salamanders of Nocturne.

The Storm Giants have fought in several of the Imperium's greatest and most pivotal wars, not least amongst them the Third War for Armageddon.

They display heightened physical strength, even for Space Marines, and there is some debate that their gene-seed may have mutated to enhance their Biscopea.

Several Magos-Genetors have made requests to study the Chapter's gene-seed but the Storm Giants have refused on each occasion.

Chapter History

Almost nothing is known about the Storm Giants' origins, save that they were created at some point after the Second Founding.

Many scholars point at their similarities in physique, markings and tactical dogma with Chapters such as the Salamanders and Black Dragons to suggest they may be descended from the Primarch Vulkan's gene-seed.

Notable Campaigns

Chapter Organisation

The Storm Giants are organised in accordance with the tenets of the Codex Astartes.

Chapter Combat Doctrine

Being a Codex-compliant Chapter, the Storm Giants can adapt to any circumstance that may occur on the battlefield. Nevertheless, many scholars have found similarities in their tactical tendencies to those of the Salamanders and Black Dragons -- a preference for close-range firefights.

During the Second Purging of Lastrati, their Tactical Squads worked in concert with their Vindicators to assault the enemy defence lines, executing a 4-stage combat formation -- first, the Vindicator would launch a preparatory artillery strike, while a demi-squad of 5 Astartes gave covering fire to its left and another made a rapid advance to its right.

Then, the Vindicator would fall back as the Tactical Marines kept advancing and blocking its line of fire, and the Astartes would storm the enemy position, first from the right, then from the left. Once the defence line was overrun and both demi-squads were ready to begin this process again, the Vindicator would quickly advance and provide suppression fire.

Chapter Appearance

Physical Appearance

The Storm Giants have long been suspected of being a Successor Chapter of the Salamanders due to their similarly strong physiques.

It is unclear whether they have the same tendency to develop ebony skin, which is due to the mutation in the DNA of the Salamanders' Melanochrome gene-seed organ.

Chapter Colours

The Storm Giants primarily wear tan Power Armour. The inset of the right shoulder pauldron and the Aquila are red.

The white squad specialty symbol on the right shoulder guard designates operational specialty -- battleline, close support, fire support, Veteran or command.

A black High Gothic numeral is stenciled on the centre of the squad specialty symbol which indicates squad number.

No company markings are displayed.

Chapter Badge

The Storm Giants' Chapter badge is a stylised red thunderbolt, pointing upwards and centred on a field of tan.
