The Iron Hearts are a chapter of Space Marines. At some point in recent times, a Chaos Lord gained entrance to one of their training centers via the body of a failed Space Marine. When this Chaos Lord manifested in their system, fought the Chapter and all but annihilated them. Only two companies, the Sixth and Tenth, remain at partial strength.
Behind the ScenesEdit
- The Iron Hearts were mentioned by name only in the novel Into The Maelstrom, specifically on page 199 in the short story Hell in a Bottle, written by Simon Jowett.
