Furious Abyss - Destruction of the Furious Abyss: Cestus and his remaining Loyalist vessels hid behind the bulk of Bakka Triumveron to keep the Furious Abyss from sending torpedoes after them. Tracking the Word Bearers' vessel, they headed on course for a Mandeville Point Warp jump vector intended to take the Traitors on to Macragge.Cestus finally devised the truth of the Furious Abyss' plans to assault the Ultramarines' homeworld once he saw the intended destination of the massive battleship. Once in the Macragge System, the Furious Abyss intended to attack Formaska, a dead moon. A direct assault against Macragge would be suicide. But the debris from Formaska's destruction striking Macragge would achieve their ends indirectly.The XIIIth Legion would be forced to divert forces from the muster point on Calth to the aid of Macragge and would become caught in the subsequent asteroid storm of the moon's demise once they translated into the Macragge System from the Warp. The Word Bearers would then be able to strike the Ultramarines fleet as it was divided and damaged by the asteroid assault, allowing the Traitors to take them utterly by surprise.This assault would not destroy Macragge outright, but it would kill tens of millions of innocent civilians and eradicate a good portion of the Ultramarines Legion's strength. The Furious Abyss would then use the debris like a shield, allowing it to get past the warning stations and satellites around Macragge and draw close enough to unleash a viral payload on the world's inhabitants.The juggernaut vessel would be powerful enough to weather the inevitable storm of fire from Macragge's Defence Lasers. The death toll from the viral strike would be near-total, wiping out the population of the Ultramarines' homeworld, the jewel in the crown of their Realm of Ultramar.Roboute Guilliman and the Ultramarines Legion would be divided, some of their forces probably destroyed on Macragge, when the remainder of the Word Bearers' fleet, commanded by Kor Phaeron, would strike at Calth. It would be doubtful if the XIIIth Legion would ever recover its strength should the Word Bearers' plot succeed. Cestus determined that the Furious Abyss had to be stopped at all costs to prevent the total destruction of his Legion and its homeworld.The Wrathful limped from the Warp and went immediately to battle stations. Beams of azure light lit up all the way down the Wrathful's flank, and in seconds the blazing fury of her Lances was unleashed. Explosions rippled down the armoured hull of the Furious Abyss, together with the immense blast flares of Void Shield impacts.These wounds were a mere sting to a beast as massive as the Abyss-class Battleship, and the Word Bearers vessel responded with a devastating salvo of its own. As the crimson rays of the Furious Abyss' broadside cannons bloomed, the Wrathful was already moving, trying to bring the enemy vessel's prow abeam of its Lances.The shields of the Loyalist warship disintegrated under the Traitor battleship's assault and the aft decks were raked by deadly fire, explosive impacts sending out chunks of debris and spilling swathes of crew into the freezing black of the void. Still, the Wrathful endured, its last ditch manoeuvre bringing it away from the deadly barrage.With Cestus leading the assault himself, boarding torpedoes soared from the Loyalist vessel's prow, followed by a second volley from the Lances. The Wrathful endured, despite the brutal barrage it sustained from the Furious Abyss, which allowed the Loyalists' boarding torpedoes to reach the massive vessel.The Furious Abyss turned its full armament against the Loyalist aggressor. The damage sustained by the Wrathful slowed it, but even then it could have fled if its crew had so desired.Instead, the Loyalist vessel stood its ground, making a defiant last stand. Lances flashing, the Wrathful poured everything it had left at the Word Bearers battleship. Sadly, it was not enough. The Furious Abyss turned, and unleashed the hell of its own broadside.Cestus linked up with Skraal within the bowels of the Traitor battleship and led the desperate boarding action which would ultimately prove successful in eliminating the threat of the Furious Abyss. Cestus, Brynngar and Skraal managed to sabotage the Furious Abyss ' plasma generatorium, beginning a chain-reaction that would result in the destruction of the massive vessel.As the great dreadnought began to explode around them, Cestus finally confronted the Word Bearers Fleet-Captain Zadkiel, who was attempting to flee, and managed to kill him, though he sustained mortal wounds himself. As Cestus lay dying, his world quickly turned to fire around him as he fell bodily beside the corpse of Zadkiel.The Furious Abyss was all but destroyed, as was the Traitors' plan to cripple the Ultramarines Legion and destroy Macragge. That thought gave Cestus some solace in the moments before he died, as he thought of Macragge and its glory.His duty done, he was content, as the sweet release of death overcame him. The massive explosion of the Furious Abyss served as his funeral pyre.
