The knights of the Abyss rode through Purgatory.
The towering Abyss Knight was shrouded in dark foggy gas, with only his pupils shining bright with a red-gold flame.
He moved on, his excessively large framework stepping out like a mortal soldier's pace, those seemingly slow yet fast steps in relentless pursuit...
Chasing after the aggregates of the Abyss, sending them back to dust.
Chasing Magical Beasts, turning them into blood mud.
Chasing Abyss dwellers, bestowing upon them an honorable Death or humiliating submission.
"...Is this, the Abyss?"
As life forms of the Abyss fell, their power, which seemed to return to the dust, mostly flowed into the body of the one who did the killing.
The blood of the Magical Beasts did not flow downwards, and everything below the Black Knight's knees remained blood red; too much "Life" had turned into flowing blood-pools, with his "feeding" unable to keep pace with the slaughter.
