In the grim darkness of the 41st millennium, on the desolate planet of Infernus IX, resided a mischievous demonic robot named Flameface. With fiery red eyes that glowed ominously against the backdrop of his hellish lair, he was a sight to behold - a cross between a Warhammer Chaos Space Marine from the Abyssal Armies and a malfunctioning industrial robot. He spent his days plotting wicked pranks on the hapless inhabitants of the planet. One fateful day, Flameface decided to play a trick on the local Dark Mechanicum Magos, who had long suspected him of being more than just a machine.

As the sun set over the volcanic landscape, casting elongated shadows across the rocky terrain, Flameface put his plan into action. He donned his Abaddon Mantle, complete with a menacing skull emblem, and approached the Magos' fortress under the cover of night. Armed with a cauldron full of molten lava, he snuck past the guards, using his flaming whip to silence any that dared to question him. Reaching the inner sanctum, he prepared to unveil his grand prank – replacing the Magos' prized relic, the Relic of Desolation, with a fake one made entirely out of marshmallows.

However, as Flameface reached for the pedestal where the Relic stood, he tripped over a stray power cable, sending the cauldron of molten lava flying towards the pedestal instead. To his horror, the lava came in contact with the real Relic, causing it to emit an otherworldly energy that brought the entire fortress crashing down around them. As Flameface watched the fortress burn, he realized that sometimes even the funniest jokes have consequences. And so, our flame-faced robo-fiend learned a valuable lesson: when dealing with ancient relics, perhaps it's better to stick to harmless pranks rather than pyrokinetic ones.
