The player "Ze" carefully secured the blue and gold MK IV power helmet on his head, and the moment he did, the visor's display system flared to life, laying the surrounding environment and tactical data out clearly before his eyes.
As a temporary recruit of the [Ultramarines], he now stood within a hall steeped in order and classical grandeur.
There was none of the forge-heat and furnace smell of the Salamanders here, nor the grim menace of certain other Legions.
Instead the air carried a sense of reason, efficiency, and meticulous clarity, as though everything around him ran according to some perfectly optimized process.
A few hours earlier, when the event's assessment system had scanned him, two very different Legion emblems had lit up for his choosing: the steady, rational "U" insignia of the Ultramarines, and the other, the savage, snarling skull-and-chain-axe emblem of the World Eaters.
"World Eaters?" Ze had frowned at the time. He wasn't wholly ignorant of Warhammer 40k lore, and he knew well enough just how bloodthirsty and mad that Legion would become in the future.
Even though the event was set before the 30k schism, choosing a Legion so laced with instability had made him instinctively recoil.
What he sought was controllable tactics, precise coordination, and a rational path to victory, not unrestrained fury. Barely hesitating, he had chosen the "U" insignia that symbolized order and discipline.
Now he stood in the assembly hall the Ultramarines had prepared for this dueling tournament.
The hall's walls were built from smooth white stone and dark blue alloy plating, carved all over with star charts of the Five Hundred Worlds of Ultramar and inscriptions from military codices.
The air held a mingled scent of preserving oil, ozone, and something like old parchment mixed with metal.
Directly ahead of him stood a true giant.
Roboute Guilliman, Primarch of the Ultramarines Legion, Lord of Ultramar's Five Hundred Worlds.
He wore no helmet, revealing a face that combined the classical grace of a sculpture with the iron resolve of a soldier.
A golden laurel wreath, symbol of victory and dominion, sat upon his neatly combed golden hair, striking a fine balance with his finely wrought dark blue power armor.
His very presence was the embodiment of "rational strength" and "civilized rule," his gaze as sharp as a hawk's, yet carrying a deep, deliberate calm.
At this moment, the Primarch's eyes rested on Ze with the utmost gravity.
"Soldier," Guilliman's voice was not loud, but it carried an unquestionable weight, every syllable clear and heavy with meaning, "you will step onto this honor duel between brother Legions as a recruit of the Ultramarines.
This is not merely a personal trial. It is a moment in which you represent our Legion, and the order and glory of Ultramar's Five Hundred Worlds."
He leaned forward slightly, those all-seeing eyes seeming to look straight into the depths of Ze's soul.
"Remember: every sword you swing, every block you make, every tactical choice you take, carries my name with it.
The name of Roboute Guilliman. We pursue victory, but the manner of that victory matters just as much.
Master strength with reason, restrain valor with discipline, and let wisdom light the path ahead. This is the way of the Ultramarines."
Ze felt a heavy weight of responsibility settle onto his shoulders.
He knew full well that the figure before him was a virtual construct, a product of Medici's code and design, yet the conviction in Guilliman's words, that unwavering commitment to an ideal, that sense of responsibility to the collective, that almost exacting pursuit of "doing what is right," reached him all the same, carried through masterful character portrayal and atmosphere.
He straightened his posture, the servos of his power armor humming softly, and mimicking the bearing and tone he remembered from other Ultramarines, he answered solemnly: "Understood. I will not fail the name of the Ultramarines, nor the glory of... Ultramar."
He paused for a moment before speaking the title that was so natural within Legion culture, yet still felt somewhat foreign on his own tongue: "My father."
Guilliman gave a slight nod, a faint, almost imperceptible curve of approval and expectation crossing his face.
To a Primarch, every warrior of his Legion was, in truth, his "son," an extension of his gene-seed and his convictions.
At that moment, the holographic projection at the center of the hall flared to life, and the results of the first round's draw began scrolling across it.
Every Ultramarine's gaze fixed upon it at once, and the atmosphere turned solemn.
When the matchup list settled into place, Guilliman's normally composed expression darkened, almost imperceptibly. He turned his head toward Ze, his tone calm but carrying a note of unmistakable, almost helpless gravity.
"Your first opponent comes from the Salamanders Legion. My brother, the scion of Vulkan."
He offered no further tactical analysis, but in those sharp blue eyes was written, plainly, this will be no easy fight.
Ze's heart beat a little faster.
The Salamanders... that Legion known for their black skin, red eyes, extraordinary toughness, superior strength, and mastery of the forge.
Their warriors might not match the Ultramarines in tactical versatility and precise coordination, but that pure, unyielding resilience and unbreakable fighting spirit, born of forge-fire and hardship, would make for a brutally difficult opponent in single combat.
Especially since his opponent was, like him, a player-controlled "Chosen," not some fixed AI pattern.
Who could this player be, the one who had chosen the Salamanders? How would he wield the traits of that Legion?
Guilliman seemed to see the flicker of thought crossing Ze's mind, and spoke again, his voice returning to perfect calm.
"Do not fear the gap in raw strength, nor let yourself be deceived by outward roughness. Vulkan's children have inherited both his mercy and his tenacity, but their way of fighting is direct and effective.
Play to your strengths: speed, precision, and your mind. Meet the forge-fire of Nocturne with the wisdom of Ultramar."
"Yes, Father!" Ze drew a deep breath and sealed the visor of his helmet shut.
On the display, his opponent's information had already updated: an unfamiliar ID, and the emblem of the Salamanders Legion blinking beside it.
The blue that represented the Ultramarines and the deep green that represented the Salamanders were about to collide within the ancient arena.
Ze tightened his grip on the bolt pistol and power sword in his hands.
He represented not only himself, but Guilliman's teachings, the traditions of the Ultramarines Legion, and the light of rational order that the Five Hundred Worlds of Ultramar symbolized, a light that sought to stand against the cruelty of the universe.
And his first trial would be to face that wall of unyielding forge-fire from the volcanic world, the toughest one of all.
