Raven Guard - Raven's Flight: Corax survived the crash and quickly ordered the remaining warriors of his Legion to regroup. He learned to his shock that a large percentage of his Legion had been utterly annihilated during the ensuing slaughter. They took to the highlands of the surrounding hills and to the shadows, hiding from their relentless pursuers.During their flight, their position was nearly discovered by a roving armour column of traitorous Iron Warriors, but they were destroyed in a Raven Guard ambush and wiped out before they could report what they had learned.Thirty solar days after the initial planetary assault, the future looked grim for the fleeing Raven Guard survivors. They had received no word from either the surviving Iron Hands or Salamanders Legions. Corax ordered his warriors to dig in and hold position at Lurgan Ridge while he undertook a lone reconnaissance of their original drop site to determine their options.Utilising his innate psi-abilities to escape detection, Corax successfully conducted a reconnaissance of the Traitor Legions' positions around the heavily fortified drop site. Though the Primarch informed his men that his mission was to reconnoiter the drop site, his primary objective was to scour the Urgall Plateau for the bodies of his fallen sons, but he failed to find them.After 98 solar days of relentless pursuit, the Raven Guard survivors were finally backed into a literal corner. Caught upon a windswept mountainside, Corax's Legion remained resolute. Behind the peak stretched the great salt plains that had forced them into this last, defiant stand.Ahead of them massed the might of the World Eaters, the rage-driven Astartes Legion of Angron, who strode at their head roaring for the blood of his brother. A sea of white and blue World Eaters Astartes spattered with the red of gore swept up from the valley intent on the destruction of the Raven Guard.Maddened by their neural implants and driven into a battle-frenzy by inhuman cocktails of stimulants, the berserk warriors of the World Eaters pounded up the sloping mountainside while their tanks and guns provided covering fire; every warrior bellowed his eagerness to fulfill the blood oaths he had sworn to his Primarch.But before they could utterly eradicate the surviving Raven Guard Astartes, the World Eaters were attacked from an unexpected quarter. Broad-winged aircraft plunged down from the scattering of clouds, missile pods rippling with fire. A swathe of detonations cut through the ranks of the World Eaters, ripping through their advance companies.Incendiary bombs blossomed in the heart of the approaching army, scattering white-hot Promethium over the steep slopes. Corax looked on with incredulity as blistering pulses of plasma descended from orbit, cutting great gouges into Angron's Legion.The roar of jets became deafening as drop ships descended on pillars of fire: black drop ships emblazoned with the badge of the Raven Guard. The Legionaries scattered to give the landing craft space to make planetfall. As soon as their thick hydraulic legs touched the ground, their ramps whined down and boarding gateways opened.The Raven Guard met their rescuers in stunned disbelief. These drop ships were part of a desperate rescue mission that had been devised by Commander Branne, a Raven Guard Captain who had been left in charge of the Legion's homeworld of Deliverance.Without further delay the Raven Guard survivors quickly prepared for embarkation and escaped aboard the drop ships, breaking for orbit and leaving behind the frothing berserkers of the World Eaters, their angry Primarch futilely baying for blood.Meanwhile, the Alpha Legion had secretly infiltrated the Raven Guard during the Drop Site Massacre, surgically altering their own operatives to resemble dead Raven Guard Astartes and then inserting them into Corax's Legion during the chaos of the chase on Istvaan V.Alpharius Omegon had been told by the secret alien organisation known as the Cabal that the XIXth Legion was going to receive an extremely valuable, top-secret asset that would be of great use to the cause of Horus.Impersonating Horus, the Alpha Legion Primarchs ordered a pursuing World Eaters fleet to stop all action against Branne's ships, so that the Raven Guard would survive the slaughter on Istvaan V and come into possession of the asset, which the Alpha Legion's infiltrators could then steal.Corax never knew how Branne had managed to make his way to Istvaan V, but he was grateful for the rescue. Branne himself was reluctant to reveal what lead him to Istvaan V, and considered the topic sensitive since he had only acted after repeated, inexplicable prophetic "dreams" seen by Marcus Valerius, Praefector of the Therion Cohort, the Imperial Army regiment which was part of the Raven Guard's Expeditionary Fleet.Deadly absolution at the hands of Angron would have been a righteous end for the XIXth Legion, but with all things considered, Corax was glad that he would survive to fight in the Emperor's name again.Following his and his Astartes' dramatic rescue from Istvaan V, Corax took the time to review the organisation of the remnants of his Legion. Including the companies of Commander Branne who had been left behind to command the garrison of Deliverance and had ultimately been responsible for rescuing the Legion's survivors from the disaster at Istvaan V, he had fewer than 4,000 Astartes of varying ranks and specialisations remaining.The majority of these Space Marines he formed into the "Talons" -- tactical companies under Captain Agapito's command.The survivors of the various assault platoons, along with several Dreadnought-interred veterans, were formed into the "Falcons," led by Aloni Tev.Lastly, the handful of Raven Guard Bike Squads, Land Speeders and aircraft crews still remaining were combined under the command of Captain Solaro An and given the designation "Hawks."The Raven Guard's Apothecaries had suffered during the Drop Site Massacre as well. It appeared that the Traitors had specifically targeted them from the outset of the battle. Only seven managed to survive, and even with only fifteen years in the Apothecarion, Apothecary Vincente Sixx was appointed as the Legion's new Chief Apothecary by the Primarch himself.
