Onyx The Indestructible is the Primarch of the twenty seventh legion, AKA The Stone Men. He and his legion made a valiant sacrifice on Isstvan, in which over 40,000 Stone Men were massacred defending the remaining loyalists so that they could escape. He died defending and defeating the Horns of Ruin during the siege of Neolithus.

Appearance and Personality

Onyx is a massive ox of a man, even by space marine standards. He is over 12 ft. tall, and by far the largest of the Primarchs. He has a well-built frame, with solid muscles and tough skin. His complexion is stained tan-grey, from the decades of stone working he did on Neolithus. His face is chiseled and stern, yet calmly humble. He has a round, shiny, bald head, with white muttonchops and a long, braided beard. When not in his stony artificer terminator armor, he is usually in traditional Neolithian garb: a brown or tan toga over a white undergarment and dark brown working boots.

Onyx is a very willful man, and will most definitely see any task he is given finished, no matter what. This also means he can be very stubborn; he will not budge for a moment on anything he believes strongly enough in, even to his superiors (The Emperor). Despite his incredible determination, Onyx is a humble man who does not see himself as the powerful being he is, and connects more deeply with the lower citizens of the Imperium than most of his space marine peers. With his stubbornness comes a deeply ingrained sense of moral duty and justice, something that he has come to be remembered by. He would often put the lives of Imperial men and women in priority of his own, and his marines followed his example. He has even advocated for xenos and non-Imperials on occasion, seeing no reason to cause violence where there is no need of it. He once said: "I do not fight because I derive pleasure from doing so; nor do I abhor violence against the criminals and enemies of mankind. I simply fight because it is what is necessary, and I will gladly do whatever is necessary to protect the people of this Imperium. If it is not necessary, I will not fight. It is as simple as that." . This has put him at odds with many other Imperial leaders before, even the Emperor himself once or twice. Regardless of his somewhat unorthodox views, Onyx is held in the highest regards among his brothers and the populace at large, especially after his immense sacrifice and tragic death.

Youth

Onyx was delivered unto a relatively primitive world, Neolithus. Inhabited by strong, hardworking men and women, here is where many of Onyx's defining characteristics came into being. He was raised by unknown parents, and soon left to work in a quarry as a stone mason. According to very old records recovered from Neolithian archives, Onyx may have even had a wife and daughter (these claims are hotly disputed and discussed even into the 41st Millenium). He epitomized the common, dutiful working man, despite his extraordinary abilities and stature. He never sought out leadership, and only became the leader of Neolithus when it was thrust upon him in the form of a massive rebellion against the corrupt guilds that controlled the planet.

Arrival of the Emperor

When the Emperor came to Neolithus in order to recruit Onyx, He was met by stern refusal. Onyx did not believe the Emperor, but issued him a challenge: If he could beat him in a test of strength, he would concede and join him. They struggled against each other for an entire 24 hours, before Onyx was finally defeated. Onyx gladly joined his father among the stars, and united with his legion.

Role in The Great Crusade

After training and molding his legion, Onyx went to test their might for the first time by repelling a great ork WAAAGH at the Imperium's doorstep, on the planet of Fenris. He led his legion valiantly, and it is here that he earned himself the moniker "The Mountain of Fenris", as he held is ground even against the greatest of odds. His next challenge was the Wars of the Colossi, in which he led the Stone Men against the horrible Jormmund by defending and retaking worlds in the Segmentum Ultima. He personally felled about 50 titans, leading squads of elite terminators into the aliens' hearts, and detonating melta-charges. It is this that earned him the name "Titan-Slayer", and gained massive popularity within the ranks of the Imperiun.

During the Heresy

Onyx defended his loyalist brethren at the Isstvan Massacre, sustaining 7 heavy bolter rounds to the shoulder, and 10 in his torso as well as many various burns and fractures. He fell back to Neolithus, only to find the Horns of Ruin waiting for him. Onyx fought Kranios the Destroyer, and his daemon prince form as well. He defeated him by breaking the Horn of Ruin in half, and killing himself in the process.
