Navar Hef - Attack on Ravendelve: The first sign of enemy activity was a long-ranged bombardment of the Magnus Casei, an Imperator-class Titan of the Legio Vindictus which had been standing guard over Kiavahr for several centuries. As Ravendelve’s macro-cannons towers engaged in the artillery duel with their gigantic foe, an armoured column of Guildsmen, escorted by four Warhound-class Scout Titan approached the curtain wall of the facility and began blasting at it. Divided between the need to repel the Magnus Casei and scare off the more agile Scout Titans, the defence turrets were soon overwhelmed. The curtain wall still held when the enemy struck from within: a Thunderhawk bearing the colours of the Raven Guard which had just deivered its complement of reinforcements veered off his course and attacked Ravendelve’s gatehouse, killing many Legionaries and allowing infiltrated Alpha Legion Legionaries that had been masquerading as Raven Guards since Istvaan V to take the gatehouse and open it. With the complex effectively breached, the Alpha Legion and their allies could now make their move for their true objective: the Primarch-gene-seed and data they had previously corrupted.Despite the dire situation the Raptors were not called upon to aid in the defense of Ravendelve. Disciplined, they remained within their cells, knowing that some kind of fighting was going on from the sounds that penetrated into their quarters, but with no one to turn to or in charge they simply sat idle. Despite the presence of both Commander Solaro and Agapito, none of them had taken charge of Ravendelve’s defence, it came down to Chief Apothecary Vincente Sixx to organise the defence of the gene-seed vault. Acting upon direct orders from Corax, Sixx began the lock-down procedure of the Apothecarion and gene-seed vault but with no one to turn to resolved himself to personally make the short trip to the next armoury to fetch the necessary demolition charges should circumstances dictate him to ensure the destruction of the gene-seed. Sixx was immensely relieved when upon reaching the elevator that would take him directly to the armoury he encountered Commander Solaro, flanked by a squad of Raven Guard Legionaries, a relief that quickly turned to shock when the Commander stabbed him through the chest with his Power Sword.This would then mark the beginning of the Raptor’s involvement, as the grievously wounded Vincente Sixx - left unguarded by the Traitors - managed to crawl to the next cell, Hef’s cell and tasked the Raptors to protect the gene-seed. To help them in their task, the Chief Apothecary relinquished his personal sidearm, a simple Bolt Pistol, but most importantly his own gene-imprinted masterkey that would allow the Raptors to arm themselves. Quickly releasing their comrades and splitting up into squads, the Raptors joined the fight for Ravendelve. Unarmoured they were not quite so resistant as a true Legiones Astartes, but their mutations had imbued many of them with superior pain thresholds and regenerative abilities which meant that even unarmoured the mutated Raptors could survive a direct hit form a Bolt, as the Alpha Legion was soon to find out. Outnumbering the enemy, the Raptors stormed the Apothecarion, where the Alpha Legionnaires in disguise were planting demolition charges in order to destroy the XIXth Legion gene-seed. A furious firefight erupted in the subterranean levels of Ravendelve, but eventually the leader of the Alpha Legion, the infiltrator masquerading as Commander Solaro sacrificed his troops in an attempt to reach the landing pads.Having already brought down more than half a dozen Traitors, the Raptors charged the two survivors and butchered them, thus securing the Apothecarion. Several of the Raptors had died in the fighting and Hef himself had taken a Bolt to the chest and been severely wounded. As Corax himself arrived with reinforcements from Deliverance and a relief column of Mechanicum troops attacked the Guilders that were still laying siege to Ravendelve, the battle definitely turned into the Raven Guard’s favour. Realizing his Legion had been infiltrated, Corax put his trust into those whose loyalty could not be questioned: the warriors of the Adeptus Custodes and the Raptors. Ordering his own Legionaries to stand down and submit to full genetical testing, the security of Ravendelve fell to the Raptors - both mutated and pure - which uncovered and even had to slay several of the Alpha Legion’s infiltrators that tried to escape now that their discovery was assured. Nef however did not participate in this effort as his wounds were being treated in the Apothecarion. Corax himself came to visit him and lauded the Raptor’s sense of duty and quick reaction-time. The Ravenlord further confirmed that even in their present condition, the Raptors were of the Raven Guard and that they would be inducted into the Legion and counted amongst its battle-brothers. The Raptors, both those genetically pure and those heavily mutated, would take to the field as warriors of the Legiones Astartes of the XIXth Legion; they would be Raven Guard.
