The Betrayer pulled his axe from the Ultramarine as he heard his name called. The weapon came free with the always-satisfying crunch, but left behind some teeth. Khârn frowned at this; the line chainaxe was leagues behind Gorechild in every way, but with his main weapon confined in the armoury for maintenance, he had to make do with spares.
He walked over the blood-soaked mud and several more bodies - enemy and "friendly" alike - to where the call had come from. The Triarius was standing with his back to Khârn, and for a moment the killer of Skalathrax gave serious consideration to the idea of gunning his axe and burying its whirring teeth into the champion's back. He felt pressure at the back of his head as the Nails stirred at the thought, but Khârn forced their rage down. For now, anyway.
The Triarius gave no hint of acknowledging Khârn's arrival, but nodded at the Ultramarine at his feet. "This one is still moving."
The loyalist was, judging from the armor markings, captain of the chapter's 4th battle company. He had one good arm left, his plastron had been kicked in and a gaping wound cut deep into the left side of his torso, armor and flesh alike burned away by a power blade's disruption field. To his credit, his face was in one piece save for some bleeding from the mouth and nose. The Triarius kicked the man in the gash, receiving a pained grunt in reply. Khârn came to stand at his Legion brother's side.
"Name?", he asked the crimson-clad champion.
"I tried to ask politely, but he isn't much of a talker", the Chaos lord replied. The Ultramarine grunted again and spat blood at Khârn.
"Let me", Khârn ventured and took a step forward, raising his axe.
"No", the Triarius growled, "he is mine."
The side of Khârn's mouth twitched. "Ruining my fun?"
"I saw him first", the champion said, stepping closer to the loyalist captain. He adjusted his grip on the halberd. "And from the looks of that cut, wounded him too. It’s only right that I finish him."
Khârn didn't make a move despite the growing burning inside his skull. "You have an honour code now? Is that mockery of this whelp, or me?", he asked. The fingers on his axe's trigger twitched.
"Honour should never go further than the simple concept of two men meeting in battle for the sole purpose of one killing the other", the Triarius said. "Anything more is a waste of time. This is a much simpler, older principle."
The champion powered up his polearm. "I call it "finders keepers"."
Khârn looked at the Triarius, then at the Ultramarine. A muscle pulled at the corner of his eye. "You know I will kill you for this one day, Delvarus."
"It's all the same to me", Delvarus replied as he raised his halberd. "All the same to Him."
