Ember Dragon

This red dragon came from the desolate northern lands, coveting all the power in the world. He was once known as the Fury of the Mountains, the Embers of the Burned, the Gilded Calamity, the Dragon of Thunder and Flame, the Reaper of Life. But when the players, called "Starfallers" by the prophets, descended, he gained a new title—Master of the Scourge.

"I, control the Scourge!"

The red dragon stood on the astral dreadnought, spreading his wings that blotted out the sky, and spoke thus.

This is the story of a hardcore old player who transmigrated into Erezege as the world boss red dragon from his previous life, pursuing individual power and building his own multiverse empire.
