The White Panthers are a Codex Astartes-compliant Loyalist Chapter of Space Marines Founded in 738.M41 during the 26th Founding. They are a Chapter of unknown origin, but are highly suspected to descend from the Ultramarines' gene-lineage due to their predilection for being strict followers of the Codex Astartes.

Notable CampaignsEdit

  • Kethra Secession (332.M39) - In the year 332.M39 the White Panthers responded to a transmission made by an Inquisitor named Bastalek Grim, who had uncovered the plans of the planetary government of Kethra to secede from the Imperium. A White Panthers strike force proceeded to completely destroy Kethra's military capabilities, devastate its Planetary Defence Forces, storm the Imperial Governor's palace, and execute the world's traitorous leaders and nobility. Inquisitor Grim saw this as needlessly rendering an Imperial world essentially defenceless.
  • Thagra IV Rebellion (Date Unknown) - When the planet Thagra IV was invaded by the Chaos Space Marines of the Alpha Legion, the White Panthers were sent to liberate the planet. The planet had a large mutant population who served as the slave workforce in the planet's manufactoria. During the rebellion, many of the mutants joined the Alpha Legion's defence, while some remained Loyal and resisted the invasion through guerrilla warfare. The White Panthers eventually drove the Alpha Legionaries off the surface of Thagra IV. The Chapter then proceeded to round up most of the mutants. This included even those mutants who had fought against the invading Alpha Legion, for the White Panthers considered all mutants to be Traitors to the Emperor. Though they intended to execute the entirety of the mutant population, the Inquisitor Gregor Eisenhorn forced the White Panthers to spare the lives of the Loyalist mutants.
  • Dyathi Cluster Rebellion (998.M41) - In the year 998.M41 the White Panthers crushed a systematic rebellion against the Imperium in the Dyathi Cluster. Chapter Master Jorus Shadowmaw was killed in this action. His replacement is not currently listed in Imperial records.
