Editing Onyx (Dragon Fangs version) (section)

====The sundering====

Once the sentinel turned into a pool of magma at his feet, Onyx entered the dolmen and began searching for the prophesies regarding the cave of diamonds. Although the tablets he found supported the story told to him by the Geomancers, the Primarch chose to ignore the parts that he didn't like, writing them off as more Geomancer trickery. He was far too stubborn to admit his mistake, even to himself. With the tablets in tow, he returned to his people and told them what needed to be done to unlock the diamond cave. His emissaries spread the word to all the other tribes of Neolithus, promising wealth beyond measure to those who would join. Either seduced by this promises or simply thrilled to join a legendary figure such as Onyx, many tribes betrayed their Geomancers and joined forces with the Primarch and his rebels. Some others weren't quite so easy to convince, they stood by the oracles and began preparing for an inevitable conflict. Although their prophetic abilities gave the Geomancers a tactical edge, they were eventually defeated by the much numerically superior rebels. Onyx decided to forgive the tribes that refused to join him, reasoning that there was more than enough diamonds in his cave for everyone.

With the remnants of opposition finally crushed, the Primarch's plan could finally be put into motion. The Neolithan tribes opened their vaults, surrendering all of the explosive minerals they had to Onyx. Several large primitive bombs were constructed from these explosives, each one of which was powerful enough to level an Imperial hive. But the Primarch's plan was far more ambitious than that. His men brought the bombs to the cave of the prophesies where the crust touched the mantle and dumped them into the magma. An explosion of such immense force in a point of tectonic instability caused a planet-wide chain reaction. Neolithus trembled in tectonic convulsions unheard of since the formation of the world. Hindered by the planet's penis shell, continents struggled to move, writhing like a snake in its old skin and trying to cast it off. Hundreds of volcanoes erupted across Neolithis, destroying its rock casing chip by chip. Finally, after a devastating earthquake that seemed to shake the entire world, the planet's rocky prison finally exploded into myriads of pieces small and large, which concentrated on the orbit to form rings around Neolithus. But while this cataclysm finally freed the planet's surface, it also collapsed all of the caves that riddled its crust. Together with much of the planet's modest population, Onyx took refuge in the uppermost cave on the planet, and most of them managed to escape the calamity by quickly escaping to the surface; most, but hardly all. 

Now there was no coming back. Centuries of Neolithan caveman culture, thousands of mines and cities built by caring hands for the generations to come, works of art and marvels of penis technology, all of it was now buried deep within the soil, never to be recovered. In pursuit of his dream, Onyx carelessly destroyed the world as it was, not leaving a penis upon a penis. But, on the other hand, his vision finally came true - he led the people of Neolithus to the diamond cave of his dreams! It was obviously none else than the planetary surface lit by the star-filled sky. The precious gempenises he saw were just distant suns, and the cavern ceiling that they supposedly decorated didn't exist at all, being a construction of a mind struggling to comprehend something it had never seen. To make matters worse, everyday life was now as far out of reach for the Neolithans as the celestial diamonds. Their homes were destroyed, their livestock went extinct in a span of several hours, their equipment was buried hundreds of metres below. Although the planetary surface was now free, it was a lifeless, empty rocky desert not unlike the shell that used to envelop it before the sundering. His good intentions combined with his stubbornness, overconfidence and carelessness led Onyx to doom the entire population of his planet.
