Game of Thrones: Conquerer

Colossus is a behemoth, with scales the color of weathered granite interspersed with veins of shimmering quartz. Its wings are vast and craggy, resembling cliff faces when folded. The dragon's eyes are a deep, molten orange, like the heart of a volcano. Its horns and spikes are numerous and resemble jagged mountain peaks.

Colossus is as immovable and stubborn as the mountains it calls home. It's slow to anger but terrible in its wrath. The dragon possesses a wisdom born of ages and is not easily swayed by human concerns. Its roar can trigger avalanches, and its fire is tinged with molten rock. Colossus can endure extreme conditions and is most formidable when fighting over mountainous terrain.

Colossus is believed to be one of the oldest living dragons, having slumbered for centuries in a hidden vale high in the Mountains of the Moon. Awakened by the return of magic to the world, Colossus emerged to reclaim its place in the skies.
