The Battle of Castobel
Below is a representative but by no means complete list of the murders
the Perjurer Phayzarus has engineered.
M41.599, The Demi-Herald:
The Deathwatch found a xenos ship drifting silently near Watch Station Klaha. Battle-Brothers boarded to investigate. Their transmissions reported quick progress through the empty vessel for two hours. However, upon the third hour, their diminishing vox signals were laced with the sound of bolter fire. When a larger Deathwatch force breached the vessel to provide support, they found the entire Killteam dead, and stripped of gene-seed. While their armour was slagged and their corpses charred almost beyond recognition, the Progenoid extraction was performed with surgical precision. At the time, the event was thought to be the work of Chaos Space Marines, but later investigation revealed a delicate modification of the plasma drives that only a skilled Magos could have accomplished.
M41.787, The Weeping Cradle:
In the Acheros Salient’s history of blood, few battles have tallied so many Battle-Brother casualties as those to hold and retake Khazant, after the ascension of Lord Militant Tetrarchus. This period saw hundreds of desperate attempts by cut-off Imperial forces to hold their ground against the forces of Chaos. At the engagement recorded as the Weeping Cradle, the Dark Sons fought a gruelling war of attrition against the Word Bearers in a mountain pass to an Imperial spaceport. This engagement was notable for the number of inauspicious events that prevented either side from conclusively ending the battle. Every time one force seemed to gain the upper hand, rockslides, vehicle malfunctions, or information leaks put their victory in jeopardy. Several picts from the site showed an unidentified red-robed figure near the field.
M41.809, The Redshale Gambit:
A Kill-team under the command of Watch Captain Drucall responded to reports of Enslaver forces spreading through the colony of Redshale on Sovereign. These reports were in error; the populace was in fact in the thrall of a dormant mutagen. The signs of Enslaver incursion were falsified, presumably to lure the Deathwatch into the infected colony. Over half of the designated Killteam perished when Redshale suddenly erupted into a mob of blood-crazed mutants. Before the Deathwatch could bring the matter fully under control, agents of the Ordo Hereticus arrived and purged the planet of all native inhabitants. Their headstrong zeal erased any chance to learn more about of Phayzarus’s infection, making it likely that the Perjurer will be able to use a similar ploy again.
