Marines Errant - Notable Marines Errant: Lieutenant Commander Anton Narvaez - Although a seasoned warrior, Narvaez was young for his rank and considered by some to be an untried leader when he was given command of the 4th Company, which also brought with it the flag-captaincy of the Strike Cruiser Star Jackal. For Anton Narvaez, the Badab War's unforeseen and bloody events would eventually see him survive against all odds and be appointed the de facto Chapter Master of the surviving Marines Errant contingent by the end of this conflict.Captain Magnar Tytus - Magnar Tytus is the captain and commander of the Marines Errant's 4th Company.Watch Captain Kail Vibius - Watch Captain Vibius has a burning desire for vengeance against xenos, which has marked him out even amongst the alien-hunting ranks of the elite Deathwatch. During the Corinth Crusade, Vibius and a squad of his fellow Marines Errant were captured by the vile Dark Eldar and taken away to the dark realm of Commorragh. Surviving the cruel treatment at the hands of his xenos captors, Vibius bided his time until he was able to seize the opportunity to escape, leading a slave revolt against his surprised captors. Eventually the Space Marines fought their way to freedom and returned to the Imperium. Vibius was swiftly nominated for the honour of representing his Chapter in the Deathwatch, and rose swiftly through the ranks until he led his own Kill-team. When his former commander Bron of the Dark Sons was mortally wounded, he recommended Vibius be promoted to the rank of Watch Captain in his stead, a role he has held ever since.Techmarine Orwell Domens - Watch Fortress Erioch has stood within the Jericho Reach for untold ages. Much of its technology has fallen into disrepair over that time, in spite of the concerted efforts of the Adeptus Mechanicus. Upon his assignment to the Deathwatch, Techmarine Domens immediately identified a number of the failing systems as consistent with artefacts that he had previously studied among his Chapter's many treasures. The majority of these were items identified through the course of Crusades, though many of these were known to be efforts that had occurred millennia apart and in dramatically different portions of the galaxy. Since his initial arrival, the Techmarine has managed to restore several of the Watch Fortress' previously inert systems to some degree of functionality. The long-term ramifications of these restorations remain unclear, for it is entirely possible that he might have repaired some equipment in such a way that it no longer functions as originally intended. However, due to his high degree of aptitude with such archeotech, Domens has worked closely with representatives of the Adeptus Mechanicus at the Watch Fortress, both in studying it and in analysing xenos-technology as it is recovered from fallen foes.Veteran Brother Donal Hageth - For twenty-three standard years, Brother Hageth has served as an overseer of Watch Fortress Erioch's Hunting Grounds, assisting the Master of the Hunt in his stewardship of the training facility. During his tenure, countless xenos have been introduced to the complex, so that hundreds of Space Marines might slay them as part of their Kill-team integration training. As he undertakes these duties in addition to his duties as a member of a Kill-team, Hageth must rely upon the efforts of other Battle-Brothers to aid in the identification and capture of xenos well-suited to the available environments. So that he might best acquire the xenos specimens that he requires, Hageth keeps an aggressive eye on the goings aboard the Watch Fortress. Some say he often knows what planets Kill-teams might visit before their assignments are even issued. All too often, he visits with a Kill-team preparing for a mission with a request that they capture a particular organism so that it might be used in the Hunting Grounds. By way of compensation, he can often offer insights into the anatomy of some of the creatures requested -- information he has had to learn so that he might fulfil his responsibility to the Hunting Grounds.
