Oku fell to her knees, clutching the arrow in her side. She screamed a silent scream, and the fortress shook beneath her. Beneath the forges, magma began bubbling upwards, higher and higher, engulfing the lower levels of the fortress. She slumped to the ground as the entire fortress began to shake, a low rumbling coming from the ground as the earth itself was torn asunder. The magma burst upwards with a spire of rock, bursting straight through the center of Steelhold. Finally, a scream escaped her mouth, and the magma surged upwards to engulf her. As the magma touched her, the fortress itself crumbled, falling down into the magma sea. Lava burst forth onto the surface, shooting hundreds of feet into the air. Clouds of ash covered the landscape, the ocean around the fortress crystalizing into obsidian. The magma was relentless, consuming everything it touched.
Then, finally, it was over. With a last eruption, the remains of Steelhold collapsed under the pressure, leaving behind an immense crater of obsidian. Where once the mountainhome had stood, there remained nothing.
As the years went by, twisted trees grew up around the site of the fortress, as if nature itself wanted to cover the catastrophe that had happened here. Steelhold fell into dwarven legend as a word synonymous with death and destruction. The figures of Steelhold became legends, its greatest heroes were revered as being almost divine. Generals prayed to Rhaken for the cleverness they would need to win, soldiers to Modi for strength in battle. Jackal was revered as a demigod, a symbol of all that a dwarf should strive for. And Emdief... Emdief was believed to be a god, who bravely fought the demon lord Oku in battle, with the assistance of the other god-champions. The exact identity of the god was uncertain: some thought said this god, others said that, some said he was a god in his own right, a member of the divine pantheon that had been unknown until that point. A few said he was nothing less than Armok incarnate, the butcher himself gracing the fortress with his presence.
And the villains of Steelhold? They became reviled as demons, creatures of pure darkness. Asmoth, Corley, Lenehan, Shank: all of them consigned, in the minds of dwarvenkind, to the deepest pits of hell for all eternity.
As time went on, and the truth became blurred into fiction, some parts of the fortress's history fell out of the history books entirely. The FractalEntity was only remembered by a few, and those who knew of him believed him to be a foreign god, one of dwarven nor demonic nature. The Day of Reckoning became lost to time, and Lenehan was accused of far worse crimes. The last days of Steelhold were a titanic clash of gods and demons, leveling the ground around the fortress and melting it into magma.
Thus ended the history of Steelhold. Or at least so it was thought...
