Whispers in the dark

This is the short story I have been writing. It is about the Alpha Legion.

WHISPERS IN THE DARK
Duncan Wright

Abaddon laughed from his charnel throne as the stranger finished his challenge.
“I am Abaddon. I am the Arch fiend, Despoiler of the Corpse-God’s worlds! I will not be defeated, by bolter nor blade, and yet, this is what you lay at my feet. What chance do you possibly think you have?”
The armoured figure simply said, “We shall see.”
“Detain this fool.”, Abaddon spat contemptuously.
Two massive terminators stomped from behind the throne, one with a pair of crackling power claws, the other hefting a chainfist and combi-bolter. A line of shots stitched across the floor, but the newcomer was nowhere to be seen.
That changed a moment later as a gladius rammed through the exposed cables and grilles at the back of the armour, and the bolter fell silent as its owner slumped to the floor.
The other terminator charged forward and slashed at the power armoured killer. The rage-filled strike was easily dodged and countered, and the legionnaire had barely the time to register his innards spilling over his knees when a well-placed bolt silenced him forever.
“So”, Abaddon boomed, “you may have defeated my bodyguards, but rest assured, for you will not-”
The crack of a teleport strike filled the room, along with the accompanying stench of ozone.
A massive figure covered in a cloak of dark reptilian hide had appeared in the room.
He said but seven words. “I am Alpharius, and I am your doom.”
Abaddon cried a wordless bellow of pure rage, rising from his seat and drawing the great sword Drach’nyen.
“I will kill you, weakling! Horus himself could not stand against me! You are an imbecile for coming here!”
The Warmaster charged at Alpharius, but the power armoured Primarch nimbly dodged Abaddon’s tremendous bulk, making a shallow slice as he moved. In the movement, the Primarchs robes were dislodged, and a rippling suit of scaled power armour was revealed beneath.
