Mystery of Vor Shelath
Before the reign of Iere, the Shattered Peak was the tallest mountain in the Dawnforge. It was also considered the most beautiful mountain in the world. Legend states that Moradin crafted the peak in the image of his domain, and that legend is honored in its ancient name; Mount Solanus.
And what mountain could possibly make a better possession for a powerful and ambitious dragon? The Dragon Tyrant Iere turned Mount Solanus into her fortress lair, carving out vast chambers for her ever growing horde while her followers excavated a sprawling network of tunnels for habitation and defense.
It was these very same tunnels that the Brothers of the White Scale exploited in their assault. With the aid of dwarven experience and gnomish ingenuity, the Brothers found structural weaknesses in the stone, and placed alchemical bombs at strategic points, bringing the upper half of the mountain down upon the Great Frostwyrm, and giving Mount Solanus its new name.
