Horus being Horus

His golden sword clove into the monsters like a fiery comet, each blow hacking down a dozen or more with­out effort. Spatters of diseased meat caked the walls, and the air was thick with the stench of faecal matter, as each monster exploded with rotten bangs of flesh at his every blow. Filthy claws tore at Horus, but his every limb was a weapon. His elbow smashed skulls from shoulders, his knees and feet shattered spines, and his sword struck his foes down as if they were the mindless automatons in the training cages.

Horus did not know what manner of creatures these were, but they had obviously never faced a being as mighty as a primarch. He pushed further up the centtal spine of the starship, hacking a path through hundreds of organ-draped beasts. Behind him lay the ruin of his passing, shredded meat that reeked of decay and pesti­lence. Before him lay scores more of the creatures, and the bridge of the Glory of Terra.
