Josh Reynolds’ novel Fulgrim: The Palatine Phoenix makes it four traitor-to-be primarchs in a row in Black Library’s The Horus Heresy Primarchs series. For this, the sixth book in the series, we see the primarch of the Emperor’s Children embark upon his first solo compliance mission, to Twenty-Eight One, or Byzas. Though ostensibly welcoming of the Imperium, Fulgrim knows he must still work hard to bring Byzas and its people to compliance. Stung by perceptions of him and his legion, he sets out with just seven of his sons to demonstrate his methods and prove his worth to his brothers.
