This 144-page codex delivers an in-depth exploration of the Kin, now expanded to include their Ironkin allies. It features 21 datasheets and five Detachments, introducing the new Prioritised Efficiency rule—units earn Yield Points by securing and holding objectives, unlocking potent combat advantages.

Additionally, the codex introduces a new Combat Patrol force, Bane-slayer’s Bulwark, alongside detailed Crusade rules, painting guides, miniature galleries, and extensive new lore for a faction that remains enigmatic to much of the galaxy.
