The Storm Wolves ...

The Storm Wolves are a chapter of Space Marines.  They are the guardians of the resource star system known as Ragnarok.  They are the second such chapter to carry the name, following in the footsteps of a Space Wolf founded chapter which failed due to cursed geneseed.

The Storm Wolves (II) were founded using Ultramarine geneseed several thousand years ago, inheriting much of the equipment of their former chapter.  They draw on the ranks of the local population, who are Germanic in nature and have retained many of the legends of the Space Wolves, with the honour of the Machine Spirit being upheld by naming most ships and vehicles within the chapter after Norse Gods.
