Clashes with the Laer Blade

The two beings leapt towards each other, Fulgrim's sword slashing down to meet the mighty creature's blade, which he now saw resembled a great sword, where once it had been a spear. Both blades met with a tearing shriek that echoed in realms beyond those of the five senses and an explosion of unlight that left those who saw it blinded. The roaring eldar god recovered first and its molten sword arced for Fulgrim's head.

He ducked, and slammed his fist into its midriff, feeling the hard impact on iron and the blistering heat that seared the skin from his knuckles. Fulgrim laughed with the pain, and raised his sword to block a murderous slash towards his groin.

The eldar god attacked with wild, atavistic fury, its blows driven by racial hatred and the ferocious joy of unbound emotion. Flames wreathed its limbs, and dark tendrils of smoke enveloped the two combatants as they struggled. Silver sword and fiery blade sparked and clanged as they traded blows, neither able to penetrate the other's defences.

Fulgrim felt his anger at this blazing monstrosity surge in his veins, its inability to do more than simply fight and kill offending his refined sensibilities. Where was its appreciation of art and culture, beauty and grace? Such a thing did not deserve the boon of existence, and his limbs filled with renewed strength, as though a new-found power flowed from his sword arm and into his flesh.
