In five years Lord Commander Solar Macharius reconquers a thousand worlds on the western reaches, and his glory carries him into the darkest sectors, places where the Emperor's light had never before been seen, even during the Great Crusade.

 * 745.M41 The Battle of Macragge - Hive Fleet Behemoth was spearheading a large Tyranids invasion force into Imperial space and were making unprecedented progress towards the Realm of Ultramar. Upon learning of the threat posed to Ultramar by the vicious Tyranids, Chapter Master Marneus Calgar at once drew up his plans. Calgar declared that the Hive Fleet would be halted at Macragge before it consumed more of Ultramar or drove deeper into the heart of the Imperium. Deeming Macragge to be the star system most immediately threatened, Calgar ordered its formidable defences to be further improved. Scant weeks later, the outrider vessels of the Tyranid fleet attacked Macragge. With the Hive Fleet destroyed after the sacrifice of an Imperial Battleship created a Warp vortex that destroyed the majority of the Hive Fleet, Calgar's surviving starships came about and roared back to Macragge to try to save the beleaguered polar garrisons. Calgar, feeling that the situation was becoming critical, sent the 3rd and 7th Ultramarines Companies ahead in their fast Strike Cruisers while his remaining damaged ships limped back to Macragge. Despite horrendous losses inflicted upon the Tyranid fleet from the orbital and polar defence grids, many Tyranid organisms were able to reach the surface of the planet. The Tyranid swarm swept across the planet with the most intense fighting in the region of the northern polar defence installations. Despite the Ultramarines fleet's ability to destroy the Tyranid bio-ships, horrific casualties were suffered by the planet's population as well as the Chapter. Calgar went down to the planet's surface, leading the 3rd Company against the ravenous hordes of the Great Devourer. The entirety of the elite 1st Company was wiped out to a man whilst defending the northern pole's defence grid. The Ultramarines 1st Company was gone and the 3rd and 7th sorely diminished.

The planet is, however, almost unrecognisable, having transformed into a hideous Daemon World. Canoness Sariah of the Order of the Sacred Rose immediately leads a force of Battle Sisters to the planet to retrieve artefacts from the Reliquary of Hope, one of the few sites to have withstood the corruption. As the rest of her forces establish a perimeter around the reliquary, Sariah leads several squads into the labyrinthine corridors beneath. For three days Canoness Sariah and her Sisters battle through monster-infested passageways; bolters cut down scores of blood-hungry Daemon-hounds and flamers burn swathes of bloated plague-beasts. Only Sariah and two Celestians survive to rejoin the Battle Sisters on the surface, having recovered the left thighbone of Saint Dolan and three pages from the Lexicon of Falsehoods from a stasis vault.

 * 991.M41 The Stromark Civil War - A political rivalry within the Stromark System lead to a civil war between the two manufactorum worlds, Stormark Primus and Stromark Secundus, that coexisted within that star system. The escalating violence halted the flow of much needed weapons and materiel from these planets to the wider Imperium, a situation that the Departmento Munitorum's Adepts determined could not be allowed to continue without adversely affecting the security of the Emperor's realm. As a result, elements of two Successor Chapters of the Blood Angels, the Angels Encarmine and the Flesh Tearers, were despatched to the Stromark System with the mandate to end the conflict by any means necessary. The fighting on Stromark Prime was the first to cease. The first engagement by the Flesh Tearers Chapter was also the last, as stories of unstoppable Space Marines hacking a vicius and bloody path through literally tens of thousands of Stormarkian warriors quickly terrified the planet's recalcitrant population into submission. Stromark Secundus took longer to be pacified, as the Angels Encarmine used less "direct" methods than their savage brethren amongst the Flesh Tearers. Several hours of difficult combat ensued that was brought to an end when 5 of the Chapter's Furioso Dreadnoughts smashed into the Stormarkian Secundus military headquarters and tore the planet's High Command apart. The surviving officers of the planet's Planetary Defence Force wisely agreed to immediately end the conflict with their neighbours and resume meeting the system's crucial production quotas.

Refusing his request, the Eldar emissary grew angry and soon his pleas turned to threats of violence. The Planetary Governor refused to be cowed by the arrogant xenos and had the Eldar executed on the spot. However, the Governor had the foresight to heed the Eldar's threats and requested aid from the Ultramarines. Calgar responded with overwhelming force, mobilising his entire Chapter. This would be the first engagement the Ultramarines fought in as an entire Chapter since the First Tyrannic War. The Eldar launched a series of devastating attacks against the tomb complex. Though unsuccessful against the stoic Ultramarines' defenses, fully half the Astartes' number were either wounded or dead. When the third and final attack came, the Eldar looked like they were going to overwhelm the defenders. An Eldar Avatar of Khaine spearheaded the assault, breaking the Ultramarines' lines of defence and spilling into the tomb complex. Dozens of Ultramarines were killed by the mighty Avatar. Calgar valiantly fought the Avatar in single combat, and though grievously wounded, managed to kill the vile creature. With the fall of their War God, the Eldar lost all heart for the fight. Some fled without heed while others fell back in good order, but all retreated into the darkness. Despite overwhelming odds, once again the Ultramarines had emerged victorious, but in his wisdom Calgar knew that the Eldar would return for the Sceptre of Galaxian. So it was that Calgar informed Commrath's Governor that the Galaxian Sceptre would be removed from Orar's Sepulchre to Macragge, where it could be properly defended.
