The training deck of the Ember Vow thundered with the clash of will-forged steel.
Shawn stood at one end, his towering Primarch-forged frame casting a shadow across the vast sparring ground. Across from him, Roboute Guilliman, reborn and blazing with freshly awakened Haki, tightened his grip on a conjured blade of shimmering Armament. His expression was calm… but his aura was suffocating.
They moved at once.
The air cracked as Conqueror's Haki from both men collided, the shockwave rattling even the Custodes lining the walls. Observation Haki painted the world in sharp detail — every shift of weight, every tightening muscle, every intent radiating like a beacon. Guilliman's first strike was a clean arc, backed by the flawless precision of a master strategist, yet empowered by raw will.
Shawn met it, Liquid Haki forming into a crescent shield that drank the force of the blow and redirected it, turning the Primarch's momentum against him.
"You adapt fast," Shawn said, their weapons locked.
"You gave me the fire," Guilliman replied, pressing forward. "Now I'll burn the enemies of Mankind to ash."
Their clash was short — Shawn broke through with a burst of Internal Destruction Haki, sending shockwaves through the training deck. Guilliman staggered but remained standing, his grin faint. "Almost had you."
Hours later, the War Council convened.
Shawn at the head.
To his right — Valdor, silent but ever watchful.
To his left — Valen, the Inquisitor's eyes burning with Warp and Haki energy in perfect balance.
Guilliman sat opposite, flanked by Chapter Master Calgar and Ultramarine veterans, their faith renewed after centuries.
The holo-display bloomed with star charts. Valen began, his voice even:
"The Rift grows unstable in Segmentum Pacificus. Chaos cult activity spikes in five sectors. The Eldar… are watching."
"They're waiting for us to bleed," Guilliman said. "We won't."
Shawn nodded. "Then we move first."
The plan was ruthless: three prongs of attack. Shawn would lead the central strike to decapitate Chaos strongholds along the Maelstrom's edge. Guilliman would take the Ultramarine fleet and cleanse the Imperial worlds in Ultima Segmentum of all taint, recruiting loyal forces along the way. Valdor would spearhead a Custodes-Grey Knight joint strike into the Warp breach near Chogoris.
Each prong reinforced the others — every victory feeding new recruits, every liberated forge world fueling the war engine.
The first strike came three weeks later.
Shawn's fleet descended on Helbrax IV, a Chaos-corrupted fortress world. As drop-pods screamed through the atmosphere, Observation Haki locked onto every hidden daemon, every sniper's perch, every shifting shadow. His warriors — Salamanders, Custodes, Grey Knights — moved like one organism, their Armament Haki forming seamless layers of defense against the Warp's corrosion.
Shawn hit the ground first. Liquid Haki flowed from his hands into a titanic warhammer, each swing shattering daemon engines into slag. Every time the Warp's touch clawed at his mind, Conqueror's Haki surged outward, smashing the psychic link between cultists and their dark patrons.
Above, Custodes formed gleaming phalanxes, Observation Haki predicting and countering enemy movements before they even began. Grey Knights, paired with Custodes as planned, unleashed psychic storms guided by Haki precision, tearing through abominations that had haunted the world for decades.
In the streets of the hive city, Valen's voice echoed over the comms. "North sector secured. Moving on the cathedral." His power was overwhelming — Warp energy shaped by Armament Haki into devastating beams that bypassed daemonic resilience entirely.
By nightfall, Helbrax IV was silent. No cultists. No daemons. Only the banners of the Imperium — and the will of Shawn's army — standing unbroken.
In the war council after, Shawn's voice was calm but resolute:
"We keep moving. No rest. The galaxy will learn that the Imperium's will… cannot be broken."
Guilliman's eyes met his. "Then let's teach them."
