Kiavahr - Notable Locations: Diagothian Mountains - The Diagothian Mountains of Kiavahr are one of the many sites where the Raven Guard Chapter's neophytes undergo their Aspirant Trials, also known within the Chapter as the Corvia. The neophytes are tasked with finding the great species of avian raptors that lair there, killing the creatures and making decorative trophies out of the birds to prove their worth to become a Space Marine.Nabrik - Nabrik was Kiavahr's former planetary capital, the city from which the Tech-guilds ruled before their submission to Corvus Corax and the installment of the Raven Guard as the new rulers of both Kiavahr and its moon. Nabrik is both the largest and most productive city on Kiavahr, its many forges toiling day and night to provide the Imperium and the Raven Guard with goods ranking from bolter-shells and power-couplings to entire gunships. The former political power resided within the Wellmetal district, one of the oldest quarters of the city which consisted of important manufactoria-complexes that were both factory and palace. Much of the city has been undermined, offering countless hiding places to the last scions of the Tech-guilds, Hereteks and mutants that hide in the deep vaults and abandoned cellars of Nabrik. Most notoriously, one of the twin-primarchs of the Alpha Legion, Omegon, would hide within these cellars and tunnels during the infiltration of the Raven Guard Legion during the dark days of the Horus Heresy.The Rad-wastes - During the Lycaeus Uprising, Corvus Corax ordered his freedom fighters to use their atomic mining charges as improvised atomic bombs, which he subsequently used to bombard Kiavahr. The atomic fire unleashed by this bombardment burnt for almost a standard century, a daily reminder to the world not to defy their new master. When the fires mostly died down, they left gigantic bowls of glass-fused rock and heavily polluted ruins and rust-plains. One of the first bombs to fall had been aimed at Nairhub where the orbital elevator's twisted stump still accusingly points at Deliverance. The rad-wastes are a broken landscape with ruined buildings, rad-lakes and sluggish rivers, still illuminated at the time of the Horus Heresy by roaring fires where the nuclear blast had ignited gas or fuel mains. Closer to the epicentre of the blast, nothing remained and the soil was covered in heavily contaminated rust-dust that Kivahr's dominant winds moulded into ferocious sandstorms. It is a landscape profoundly inimical to Human life, but yet some chose to live there: the outcasts, the mutants, the Heretics and those that still seek to bring about the return of the Tech-guilds, all those forced to hide from the gaze of the Imperium and its allies. In 10,000 standard years, little has changed as the Raven Guard always have more pressing matters at hand than purging these wastes and the Adeptus Mechanicus has equally shown little-to-no interest in reclaiming the lost and forgotten technology which might still rest within the heavily polluted wastelands.Ravendelve - Continuously bathed in the noxious fog of the rad-wastes, a single three-storied building stood out, defended by armoured towers and lascannon batteries but otherwise unremarkable. This slab-sided fortress was named Ravendelve and was one of the Raven Guard Legion's training facilities at the time of the Horus Heresy. What made Ravendelve so valuable was its location, deep within the enormously dangerous and inhabitable rad-wastes. During the Great Crusade, Ravendelve's primary utility was as a training ground, where Raven Guard Legionaries and aspirants alike learned to cope with the harsh environment of a nuclear wasteland. Its isolation would later lead the primarch Corax to select it to harbour his most secret endeavour: the accelerated rebuilding of the XIX Legion following the crippling losses sustained during the Drop Site Massacre. Most of the fortress complex was subterranean, and the parts which were not were well-defended and located in the most inhospitable region of the planet -- isolated and secure. This must have been how Ravendelve had seemed to the Ravenlord, and yet, by a cruel twist of fate Ravendelve would become the site of one of the Raven Guard's most humbling defeats.
