Howling Griffons - Notable Howling Griffons: Chapter Master Alvaro or Kenot Friche (see Canon Conflict below) - Current Chapter Master of the Howling Griffons Chapter, who is leading their contingent assigned to fight the Plague Wars.Chapter Master Orlando Furioso (KIA) - Late in the year 220.M38 the Howling Griffons Chapter was preparing to celebrate the 5,000th anniversary of its Founding. As Orlando Furioso and the 1st Company made their way to the Chapter's homeworld, the Chaos Lord Periclitor of the Word Bearers and a substantial force of his Chosen fell upon the Howling Griffons' starship as it traversed the Arios beacon. The battle was a furious one, culminating with Periclitor and his elite Chaos Space Marines boarding Furioso's Battle Barge aboard their Dreadclaw Drop Pods. The attack crippled the Howling Griffons' starship, and the defenders were forced to evacuate aboard their Thunderhawks and salvation pods. The battle was continued upon the surface of Arios Quintus, where the survivors were surrounded and eventually cut down. The body of Furioso was mounted upon the front hull of his Thunderhawk, and though tragic, at least it permitted the Chapter to successfully recover his body and gene-seed.Captain Borganor - Borganor was the captain of the Howling Griffons' 10th Company. Much of his organic body had been replaced by augmetics. For instance, his right leg was replaced by a full bionic after Sarpedon of the Renegade Soul Drinkers Chapter severed the original. His skull was heavily scarred and had also been cybernetically repaired multiple times.Chief Librarian Mercaeno - Mercaeno fulfilled the oath of avenging Chapter Master Furioso's death by vanquishing the Daemon Prince Periclitor during the 13th Black Crusade. He then led the Battle Barge Cerulean Claw to Vanqualis in the Obsidian System to fulfill an oath to the ruling Falken family to defeat the Soul Drinkers who were mistakenly identified as the bearers of the Chaos artefact called the Black Chalice. Mercaeno had a titanic physical and psychic duel with Sarpedon in the Soul Drinkers' space hulk Brokenback. He broke Sarpendon's Force Staff and defeated him. However, before he could deal the death blow to Sarpedon with his Force Axe, Mercaeno met his demise at the hands of Eumenes, the Renegade leader of the Soul Drinkers. Sarpedon then defeated Eumenes and won the leadership of the Chapter back. Chapter Master Sarpedon of the Soul Drinkers now wields Mercaeno's Force Axe.Codicier Miguel Gricalo - In 753.M41, Codicier Gricalo, a Howling Griffons Librarian who had been seconded to the Deathwatch, undertook an extended mission to investigate the Watch Stations of the Dark Pattern in the Jericho Reach. As most of these sites are near dead or uninhabited worlds, the motives behind their implementation remain uncertain. The Librarian was motivated to undertake the study due to a series of visions that he received consistently for two years before his quest. According to records made prior to his departure, the divinations consistently told of an impending crisis that might soon emerge from this region. Several of these reports were corroborated by other psykers who worked in concert with the Codicier at the time. Codicier Gricalo's Kill-team had enjoyed tremendous success prior to his departure. Its other members, as well as his Watch Captain, were all reluctant to see the Librarian depart on this extended solo mission. However, a missive from an unidentified member of the Inquisition provided motivation for the Watch Commander to directly order the psyker to embark upon his survey of the Watch Stations. There have been no confirmed reports from the Codicier since his departure. Routine surveys of the locations included in his route show no signs of him ever having arrived. His fate remains a mystery.Dreadnought Confessor Armand Titus (KIA) - Chaplain Armand Titus stands as an examplar of the valour and perseverance of his Chapter. Titus was entombed within a Dreadnought following the fatal poisoning of his body by the Drukhari Kabal of the Crimson Libation during the Jorun Retaliation. As a revered Dreadnought Confessor, Titus remained an inspiration to the rest of the Chapter until he fell in the Badab War during a campaign in the Caradryad Sector on the world of Khymara Elipsis when he led a desperate counterattack against an overwhelming force of Executioners Astartes. The surviving Howling Griffons found the wreck of Titus' Dreadnought laid out, surrounded by a ring of broken weapons, a shattered Executioners' standard placed in the war machine's lifeless grasp.Josef Vincens - A few among Watch Fortress Erioch's complement suggest that Tactical Marine Brother Vincens has launched his own Crusade against the T'au of the Velk'Han Sept in the Jericho Reach. After two members of his Kill-team were slain during a mission to investigate Tau operations on the world of Innan, Vincens swore an oath of vengeance against the xenos. Since that time, he has undertaken dozens of missions into space held by Tau forces. None save Vincens know the precise terms of his oath, but it is clear that he is still attempting to fulfil that obligation. The other members of his Kill-team have been remarkably accommodating in assisting Brother Vincens, likely due to their own thirst for vengeance. Since swearing his oath, his Kill-team's activities against the Tau have been relentless. The majority of their time away from the worlds held by these xenos has involved filing mandated reports concerning the details of their missions and the threat posed by the Tau forces. Many suspect that Brother Vincens has become the foremost expert on the Sept's strategies and tactics within the Jericho Reach. However, due to his endless missions, none have been able to compile a comprehensive report of the information he has uncovered.
