Ryza - Honour and Glory: The fall of Salvation Isthmus opened a path for the Traitors to assault all of Ryza. Splitting in two, the Traitor forces laid siege to both continents, still desiring to claim as much of the world intact as possible.To the north, the Legio Magna embarked upon a campaign of brutal assaults, relying upon lightning attacks to overwhelm their foe before the Loyalists could regroup. This campaign achieved much success, splintering the forces of the Legio Honorum and the Legio  Crucius that stood against them.Their advance was halted at the forge city of Prosperity, where the two Loyalist Titan Legions met their foes before the city's walls and blunted their advance, momentarily throwing the Legio Magna back. This victory was to be short-lived, for dissent swept across Prosperity and malign powers were unleashed, all within consumed in a single night of bloodshed that left the city tainted, the Loyalist force abandoning it to their foe.On the southern continent the war progressed differently, perpetrated as it was by the Legio Vulturum and a decad of Legio Mortis ("Death's Heads") Titans sent by the Warmaster Horus himself to assist the invasion. The Gore Crows practiced a far more methodical form of war than the Legio Magna, preferring to savour their kills as they ground all beneath their heel in merciless conquest.As they moved further across the continent word reached Tsaue, the princeps magnus of the Legio Mortis, that the hierophant technis herself was located within the forge city of Endeavour, directing the Loyalist defences from there.Desiring to sever the head of the Loyalist forces, Tsaue gathered his Legion within the shadow of Mount Causcaut, working in concert with House Morbidia to seize control of monitoring stations constructed atop the mountain and deny warning to Endeavour of the Traitors' advance.From there, the Legio Mortis assailed the city, breaking the back of those few Legio Osedax ("The Cockatrices") Titans left as guardians. As maniples of Gore Crows moved to rendezvous with Tsaue and secure the city, Dark Mechanicum forces swarmed its streets, determined to find the hierophant technis and claim her head.In the days following the fall of Endeavour, what Loyalist Titans were able moved to recapture the city. Few in number and drawn mostly from the Legio Osedax, they were faced with a wall of Titans standing atop the broken fortifications of the city.Endeavour itself was surrounded by barren plains that offered little cover, ensuring any assault upon the city would be in full sight of the Traitors and, against such numbers, the Legio Osedax had little chance of survival, even with the assembled might of House Taranis and House Zavora by their side.Torn between duty and pragmatism, the commanders of the Legio Osedax moved to debate their options, proposing a retreat and the appointment of a new leader. This course of action was not condoned by the Knights of House Taranis and Zavora, for they were loathe to see another world they protected burnt in the fires of the Warmaster's ambition.As the sun rose on a new day, the Knight houses assembled and, as one, charged across the empty plain towards Endeavour, directly into the teeth of the Traitors' guns.Few of the charging Knights survived but those that did broke the Traitor line, using the confines of the streets to even the odds and bring down superior foes. Outside of the city, the Legio Osedax moved into action, hoping their numbers could tip the battle in the Loyalists' favour and push the Traitors from the city.
