Like a meteor, blue flames shot from the sky and became a path to the natural mountains that separated the western nations of United Sanctuary, Dragon Empire and Dark Zone. The blue flames quickly hit the mountain's snowy peaks, and formed a platform.

Walking down the staircase of fire, a draconic leader emerged from the clouds that lingered in the smooth blue sky. Once on the now watery tips of the mountains, the dragon firmly put a foot down, digging his heel into the gravel and rocks.

He began scaling down the mountains with his large claws and firm feet. Forces such as strong gales and the occasional storms of snow tried to interfere, but dragon's fires melted away the obstacles and icy pain.

There was no path, due to it being a remotely unexplored area of the sanctuary. Being on the outskirts, only the Shadow Paladin clan ever examined these mountains, but never this high. No life was there, thus was deemed useless.

However, while it was a treacherous and dangerous journey, there was one reason to scale to this height.

Once down a few hundred metres, the dragon was able to recover strength on a poorly forged path. It was crooked and narrow, with not much room for a dragon of his structure.

Tip-toeing and keeping his body slim, the dragon continued to press onwards, encircling the mountain. Looking up, he saw an icy entrance that cursed the belligerent jaws of a natural cave inside the mountain.

The dragon hugged the walls of the mountain, and began climbing up to the entrance only a few metres above him. Pulling himself up, he clambered onto the rocky platform at the jaws of the cave. He raised his hand, and released anguished blue flames that melted away the ice in his way.

At the gate of death, the leader bravely entered with his body smoking with blue fire. The crystallisation of stalactites and stalagmites melted away into milky puddles as the dragon crossed closer to the scent of power.

Despite it's meek entrance, the inside of the cave was far greater then the dragon who explored it. Squeezing past the narrow pathways, it lead into thicker and larger ones, with wide rooms adjacent to one another. The dragon was nothing but a speck in this cave.

The Progenitor Dragon of United Sanctuary - the guardian of the nation, awakened from it's slumber due to an unknown singularity - existed only in this cave with bundles of crystals. It lived in the furthest room from the entrance, which was where the fire-clad dragon was headed towards.

Upon seeing the Progenitor Dragon laying flat on it's stomach with each of it's golden banded arms by it's side, the fire-clad dragon took hold of the handle of his sword that was tied onto his back with drapes of old bandages.
