Chapter HistoryEdit

Notable CampaignsEdit

• Pandemonium of Sondheim V (997.M41) - The Agri-world of Sondheim V is overwhelmed by the Tyranids of Hive Fleet Leviathan just as the Daemon Prince M'kar the Reborn transforms the world into his own private Chaotic Pandemonium. The Sky Sentinels Chapter of Space Marines are the first to respond, but judges the world irretrievable and makes preparations to begin an Exterminatus. These preparations are delayed following the arrival of a Grey Knights strike force under the command of Grand Master Vardan Kai. Whilst Kai concurs with the Sky Sentinels' assessment that the planet cannot be recovered for the Emperor, he orders a stay of the Exterminatus whilst he and his Battle-Brothers attempt to capture the Book of Pandegaras -- the cursed tome of Chaotic sorcery that M'kar used to transform the planet below into his own private hell-world. The Sky Sentinels reluctantly decide to give Kai twelve hours in which to accomplish his mission, and the Grey Knights take to their Stormravens and deploy to the planet below. Upon landing, Kai hastily revises his time limit to a mere six hours—a nightmarish fusion of daemonic and Tyranid infestations have transformed Sondheim V into a Death World. Fortunately, running battles between the Tyranids and M'kar's daemonic thralls allow the Grey Knights to slip through the mutated landscape unimpeded, if not unnoticed. Unfortunately, when Kai 's forces reach the temple in which the Book of Pandegaras lies, they discover that the building has been almost completely surrounded and interpenetrated by Tyranid spore chimneys. Unperturbed, the Grey Knights hack their way through the xenos biomatter but draw the attention of the Hive Mind. Within seconds, Kai's forces come under attack by waves of Hormagaunts and Gargoyles. By the time Kai finally carves a path into the lower levels of the temple, larger creatures start to arrive, and the Grey Knights' begin to suffer heavy casualties. Yet as Kai finally reached the Book of Pandegaras, unexpected aid arrived. Just as the earlier strike on the Tyranid biostructures had alerted the Hive Mind, so did the violation of the Chaotic artefact by the touch of the Emperor's servants now bring forth the wrath of M'kar's daemons. The twisted ruins of the temple erupted into a three-way battle. The Tyranids bore the brunt of the daemons' attack. With the Grey Knights surrounded by Tyranid bioforms, the daemons could reach them only by carving a path through the Great Devourer's minions. Bloodletters swarmed over a Tyrannofex, only to be cut down by volleys of Storm Bolter fire. Carnifexes smashed through knots of Grey Knight Terminators only to be immolated between the sanctified flames of Purifiers and the unholy Warpfires cast by the Flamers of Tzeentch. Amid the chaos, Kai was forced to abandon any pretence of a controlled retreat and he makes contact with the Sky Sentinels' fleet, who begin an orbital bombardment of the temple site. Protected by their Power Armour, the Grey Knights weather the storm of barrage bombs that explode amongst the ruins while their Tyranid and daemonic foes are less fortunate. When the bombardment ceases, Kai and the surviving Grey Knights evacuate the doomed world before daemon and Tyranid reinforcements can arrive. Less than an hour later, Kai's strike force begins the journey home to Titan to contain the Book of Pandegaras in the Chapter's vaults, whilst the Sky Sentinels begin the Exterminatus that will destroy Sondheim V and all of the horrors on its surface. In the wake of the Exterminatus, the Sky Sentinels surrender themselves for the standard mindwipe to the Inquisition so that all memory of the worst horrors of Chaos will be wiped away.
