Watch station - Notable Watch Stations: Watch Station Andronicus - A watch station in the Canis Salient of the Achilus Crusade.Watch Station Arkhas - Watch Station Arkhas is a void station that sits hidden within the gas clouds that wreathe Arkhas VII, the Arkhas System's outermost planet in the Jericho Reach. There, it remains in constant vigil over the worlds now claimed by the Achilus Crusade's Orpheus Salient.Watch Station BelariusWatch Station Bellom -  A watch station in the Canis Salient of the Achilus Crusade.Watch Station Castiel - A watch station in the Orpheus Salient of the Achilus Crusade.Watch Station Credence - A watch station in the Canis Salient of the Achilus Crusade.Watch Station Elkin - Watch Station Elkin is unmanned, its purpose to intercept local communications to analyse signals from nearby star systems for alien threats.Watch Station Hlesan Secundus - A watch station in the Acheros Salient of the Achilus Crusade.Watch Station Hestus - A watch station in the Canis Salient of the Achilus Crusade.Watch Station Iobel -  A watch station in the Acheros Salient of the Achilus Crusade.Iron FortressWatch Station Midael - A watch station in the Acheros Salient of the Achilus Crusade. Watch Station Midael was ultimately lost to the expansion of the Warp rift known as the Hadex Anomaly.Watch Station Oertha - Watch Station Oertha is a watch station in the Canis Salient of the Achilus Crusade that is currently being used as a headquarters for the Imperial and Deathwatch forces contesting a T'au attempt to take the world of Oetha upon which the station stands.Watch Station Phaedas - Watch Station Phaedas is a largely automated, mobile watch station deployed in the Jericho Reach. It is essentially a Warp-capable void station, its structures constructed into a small asteroid. Watch Station Phaedas is a relic of ages past. Not a true watch station in the conventional sense, Phaedas is an archaeotech voidcraft that bears no resemblance to any form of starship or void station within Imperial records. If the Adeptus Mechanicus know of Phaedas' provenance, they are not forthcoming about it. Phaedas is largely automated, its myriad machine spirits (artificial intelligences) demonstrating sophistication that rivals those of the most ancient and revered of Titans. The vessel -- if it can be defined as such -- seems to operate based on incredibly complex logic paths, turning augur data into plotted courses, even able to travel short distances through the Warp without a Navigator.Picket's Watch - Picket's Watch is a watch station and starfort located close to the Damocles Gulf in the Eastern Fringe. Its forces are held in the fortress of Westkeep and are currently led by Watch Commander Jotunn. Though the Imperium's records do not detail the identity of the "Picket" that the fortress was named after, there is evidence that it was originally constructed in the Age of Strife and was discovered by the Imperium during the Great Crusade. At that time, the Imperial Fists Legion claimed ownership of the star fortress and built the fortress of Westkeep there atop the ancient ruins. The VII Legion used the fortress as an outpost to stand guard over the Damocles Gulf, but their reasons for doing so at that time have been lost to the ages. For millennia afterwards, the fortress was maintained only by servitors until the rise of the T'au Empire. The T'au's expansion soon led them into conflict with the Imperium and the outpost found itself on the front lines of the battles between the rival stellar empires. This led the Deathwatch to lay claim to the station, and they proceeded to heavily modify Westkeep's defences and weaponry. Despite these additions, Picket's Watch's chief defence remains the secrecy of its location. The fortress is readily capable of sustaining no more than three Kill-teams at a time. Nonetheless, it is the current base of operations for the Second Chamber of Watch Fortress Talasa Prime. Three Astartes Strike Cruisers are known to operate out of Picket's Watch. These include the Nemesis, Robidoux and Troilus.Watch Station Resgulus - A watch station in the Acheros Salient of the Achilus Crusade.Watch Station Skapula - A watch station in the Canis Salient of the Achilus Crusade.Watch Station Tryphon -  A watch station in the Orpheus Salient of the Achilus Crusade.Watch Station Xyston - Watch Station Xyston lies near the Calaphrax Cluster and is charged with ensuring the darkness within that blighted realm does not escape to infest the Imperium. Among its personnel are the Astartes of Kill-team Agathon commanded Veteran Sergeant Dienekas Agathon of the Imperial Fists, and comprised of the Space Wolves Wolf Guard Rurik Warsong, the Flesh Tearers Sanguinary Priest Izraefel, the Celestial Lions Codicier Kaelar, and the Ultramarines Assault Marine Tiberius.
