This thread shall cover the lore additions regarding the Emperor's Children in the book The Siege of Cthonia.
BAAL DEFIANT 008-011.M31-
Cut off from the main body of their Legion, who had ventured to Signus, several companies of Blood Angels remain on their Primarch’s home world of Baal and are besieged by Traitors, including Sons of Horus, Emperor’s Children and Mechanicum forces that have sworn allegiance to the Warmaster. Doubt amongst the Blood Angels begins to grow, moods blacken and a sombre pall is cast as many believe Sanguinius himself to have fallen whilst abroad. The plausibility of such an event gains traction after combined contingents of Iron Hands, Salamanders and Raven Guard arrive at Baal after fleeing the massacre at Isstvan V, bringing news of the death of Ferrus Manus and the unknown fate of Vulkan. United in their grief, the Loyalist Legions are organised into functional battle companies and together they resist the continued attacks of the Traitors throughout the course of the Heresy. On two occasions, major Traitor attacks are launched only to be repelled with resolute defiance bythe combined Loyalist defenders. In the interim periods, a guerilla war simmers throughout the Baal system as sorties are launched to strike at the besieging fleets; the once proud sons of the loyal Primarchs taking the fight to their assailants in a series of strikes and fades, attempting to bleed their enemy dry by inflicting a thousand cuts.
THE BURNING OF IDYLITAR 012.M31-
Following their flight from Chemos after its destruction at the hands of the Dark Angels, fragmentary bands of Emperor’s Children disperse into the region known as the Pale Stars where they regroup and establish a new domain. This expansion soon attracts the attention of the Salamanders garrisoned on Nocturne who mobilise to counter the building Traitor forces. The XVIIIth Legion wage a systematic campaign of purification, cleansing each system planet by planet, leaving no trace of Fulgrim’s debased Legion. Their aggressive campaign reaches the Idylitar system, whose primary planet had been selected by the IIIrd Legion as the centre of a new kingdom to serve as a keystone around which they would assert control of the sub-sector. All across the barren land masses of Idyl-I, the Emperor’s Children had raised great defences and fortified the orbital sphere with an interlinked network of satellite stations, controlled by an artificial sentience of ancient origin. Unable to bring effective orbital strikes to bear due to the sophisticated defence network that protects the Traitor world, the Salamanders launch boarding actions in an effort to disable the enemy guns and bring their ships into effective range. Over the course of weeks, temporary control of the relay-nodes within the defence network is wrested from the hands of the Emperor’s Children before the automated systems reroute and rebuild the network. These actions afford the Salamanders only brief windows of opportunity to bring their formidable weapons to bear upon sectors of the planet and drop additional reinforcements into the intensifying war zones on the surface. The IIIrd Legion defenders take advantage of the Salamanders’ inability to bring any superior forces to bear and only after several months of vicious, running battles are they finally dislodged from their stronghold, allowing the XVIIIth Legion forces to join their brethren in their purgation of the remainder of the region.
DESCENTS OF MADNESS 013.M31-
Several Loyalist Imperial outposts to the south-west of the galactic core record accounts of sporadic attacks by bands of horrifyingly mutated creatures, beasts and disfigured humanoids, clad in desecrated power armour bearing the barely recognisable sigils of the IIIrd Legion. Initially these incidents are suspected to be perpetrated by cult aberrants or some unknown xeno-forms, mimicking or acting at the behest of agents of the Emperor’s Children since they lack the overwhelming force and coordination of a Legionary assault, the troops conducting them seeming disorganised or overcome by a malaise. Over the space of several months the attacks intensify from relatively easily repelled incursions through to much more dangerous onslaughts, until eventually the perimeter outposts in some local clusters cease transmission of ident codes and are assumed to have been overrun or destroyed.
WAR IN THE SHADOWS-
The events that took place in the proximity of the Segmentum Solar during Horus’ march on Terra would become some of the most storied and significant battles the Imperium had ever known, overshadowing any throughout the entire history of Mankind. Rogal Dorn, the Primarch of the VIIth Legion and Praetorian of Terra, had set his defences against the inevitable coming of the Traitor hordes, and the Emperor himself waged a hidden war of his own within the Webway – the space that existed between reality and the Immaterium. Loyalist forces were drawn in to man defences that ranged from the cordon wall of the Imperial Palace itself to the distant, cold moons of Pluto. Traitor forces left ruin in their wake as they amassed and prepared to assault the most heavily defended position in the galaxy, the Sol System. The cradle of humanity was, however, not the only place that battle still raged during the latter years of the Heresy. The remnants of Expeditionary fleets, garrison forces and warbands that were still dispersed throughout the furthest reaches of the galaxy did not all voyage to converge upon Terra. Many heeded that call but were contained behind entrenched blockades and possessed numbers too few to break out and join the fight by the side of the Emperor. Traitor forces of Emperor’s Children, Death Guard, Iron Warriors, World Eaters and Thousand Sons amassed in the Inwit Cluster, effectively holding Loyalist Imperial Fists captive upon their own home world. What resources were occupied in keeping the VIIth Legion from reinforcing Terra were deemed worthwhile if they reduced the number of guns arrayed atop the ramparts of the Imperial Palace by even a handful.
Elsewhere, upon the distant world of Drussen, contingents of the Iron Hands and Iron Warriors had maintained their alliance and were oblivious to the events of the Heresy. In 010.M31 the peace was shattered with the arrival of both Raven Guard and Alpha Legion warships in open conflict. Legionary war rapidly engulfed the planet as the horror of betrayal was revealed anew. The entirety of Drussen’s capital city and billions of its inhabitants were lost in the space of a short few hours, the immense structure toppled from its gravitational harness and sent crashing into the planet’s surface. Some were embroiled in wars of their own making, ampaigns to exterminate those who they once called cousins or wars of attrition, fuelled by bitter hatred. The overarching strategic objectives of many of these conflicts were insignificant in comparison to the opportunity they represented to extract a toll, in blood, from those who had become the sworn enemy. Little thought was given to the spirit of noble conquest and expansion that prevailed during the era of the Great Crusade and instead utter destruction of the foe and any hold they inhabited became the only measure of victory.
SOLDIERS OF TREACHERY: The Emperor’s Children-
In the wake of Fulgrim’s daemonic ascension and subsequent disappearance the IIIrd Legion experienced a traumatic rebirth, falling from grace further in the pursuit of its newly awakened dark passions. The Legion dissipated into warbands that, rather than prosecute the grand strategies of the Traitor Warmaster, sought instead to find worthy opponents against which to test themselves. Few accounts cataloguing the actions of the Emperor’s Children survive, for few were the witnesses left behind to mark their deeds, but some notable instances stand out among extant records. At Baal, a large force of Emperor’s Children joined the Sons of Horus in laying siege to the home world of the Blood Angels Legion. Within the Inwit Cluster, hungry for the strategic prize of Rogal Dorn’s home world and its surrounding empire, a vast Traitor fleet led by elements of the Emperor’s Children wrought terrible destruction. Among the most sizable IIIrd Legion concentrations of force was an armada amassed by Lord Commander Eidolon who, in the absence of his Primarch Fulgrim, had become the self-appointed master of the Emperor’s Children. Seeking to validate his newfound pre-eminence among the Emperor’s Children, Eidolon hounded the Loyalists across the stars, relentlessly seeking to earn the recognition he so craved. Eventually, many of the Emperor’s Children would gather once more as a Legion at Ullanor, heeding the call of their returned Primarch to join Horus’ host bound for the final confrontation at Terra.
