First War for Armageddon - Siege of Fenris: Kysnaros' armada, including a multitude of Inquisition warships, Grey Knights vessels, and the entire Red Hunters Chapter fleet, arrived at Fenris and surrounded the planet in high orbit whilst targeting The Fang, the Space Wolves' famed fortress-monastery, for a devastating orbital bombardment.The planet was virtually undefended as the vast majority of the Space Wolves and their Chapter fleet were dispersed on missions across the galaxy. Kysnaros, directing operations from his flagship, again asked for a parlay with any ranking Space Wolf available, to which the few Space Wolves present agreed. Kysnaros asked the Grey Knight Hyperion (who commanded respect amongst the Space Wolves as the "Bladebreaker" for his role in defeating the Daemon Primarch Angron on Armageddon) and Inquisitor Jarlsdottyr to join him as representatives of the Grey Knights and the Inquisitorial Ordos, respectively. Kysnaros knew that Hyperion was for a time part of the conspiracy bent on his assassination, while Jarlsdottyr was open about her mistrust of the Inquisitor Lord -- however Kysnaros apparently wanted the best possible delegation in the parlay with the Space Wolves. The team soon arrived at The Fang for the meeting. The Space Wolves had awoken the Venerable Dreadnought Bjorn the Fell-Handed to deal with the Inquisitorial party. The ancient warrior, who had once fought beside the Primarch Leman Russ during the Great Crusade and had served as the first Great Wolf of the Chapter after Russ' disappearance, immediately received the unbidden respect and reverence of the Inquisitorial delegation, and was thought to be a more temperate and wiser representative for the Chapter than Logan Grimnar.Kysnaros asked for the Space Wolves' express obedience to Imperial authority and the chain of command, and a Penitent Crusade to be undertaken to expiate the Chapter's guilt for attacking the servants of the Inquisition. In exchange, the Inquisition and the Imperium at large would take no other action or censure against the Chapter. Bjorn was not impressed, countering that Kysnaros was asking a proud, storied Chapter that had served Mankind for millennia to kowtow to faceless bureaucrats, who ruled according to expedience rather than honour. Further, this was demanded whilst the Inquisition's orbital guns were locked on The Fang. He asked Kysnaros to make a more rigorous presentation of his case, but before the latter could start, and to everyone's surprise, the Space Wolves' Chapter fleet under the command of Logan Grimnar translated from the Warp near Fenris -- the fleet had travelled at extraordinary speed and at the cost of its Rune Priests' lives to arrive in time. The negotiations abruptly ended, and the Inquisition delegation made haste to Corel's Hope.Following yet another short and fruitless exchange between the panicked Kysnaros and the snarling Grimnar over ship-to-ship Vox, an all-out close-quarters naval battle broke out above Fenris. Despite the presence of senior Imperial Navy officers from the Battlefleet Solar, Kysnaros took command of the Inquisitorial fleet from Corel's Hope's Strategium. His panicky state disappeared, and he exhibited remarkable calmness under pressure and intricate knowledge of large-scale, complex naval tactics. He ordered half of the Inquisition assets to commence conventional-only bombing of The Fang, whose defence batteries were already engaging his armada, whilst coordinating the maneuvers and targets of the other half of his ships. Upon detection of Space Wolves boarding torpedoes approaching his fleet, he ordered the Red Hunters to counter-board the Space Wolves vessels that had fired the torpedoes.While the battle was raging, Grimnar had the Scramaseax come abreast of the Corel's Hope, where the Astartes' vessel's superior shields, armour, and broadside proved deciding factors as the Corel's Hope 's Void Shields failed first. Immediately, Grimnar and his Wolf Guard teleported from the Scramaseax to the bridge of the Inquisitorial Battlecruiser.As the Wolf Guard caused mayhem on the bridge, Grimnar sprinted towards the command throne, where Kysnaros stood. Despite resistance by Hyperion and one other Grey Knight, and the assistance of Inquisitor Jarlsdottyr, the Great Wolf quickly reached the Inquisitor Lord. Kysnaros was unarmed, yet he was a powerful psyker with telekinetic abilities. However, either he did not care to defend himself, or he did not have time to react given the Great Wolf's speed and ferocity, for Grimnar, in one swift move, unceremoniously decapitated the Inquisitor Lord.Kysnaros' death was not enough to placate the enraged Space Wolves who continued their rampage, until shortly afterwards Bjorn the Fell-Handed teleported to the bridge of Corel's Hope and bade everyone to "stop this madness." Thanks to his timely intervention and mediation, the battle ended and a truce was sought amongst the combatants.
