The story begins after Ragnarok. The cataclysmic war has ended, and the gods have fallen. The world of Midgard lies shattered, reduced to a twilight wasteland overrun by monsters and carved up by warlords. Ancient legends spoke of "Dragon-Kin" who could harness primordial power, but they are long considered myth.

A mortal blacksmith named Kael discovers a pulsating red Dragon Shard within the ruins of a temple to Thor. Upon touching it, he becomes imbued with the power of the Storm Dragon, transforming into a Dragon Knight. He soon learns he is not alone, as others are also seeking and awakening the power within these shards. A new hope for rebuilding the world is ignited.

The emergence of these Dragon Shards is no accident. They are guided into the hands of specific individuals by a mysterious, one-eyed wanderer who offers them cryptic guidance. This figure is, of course, Odin—who did not truly die in Ragnarok. He sacrificed his physical form, merging his consciousness with the World Tree, Yggdrasil. He reveals a profound truth: Dragons were never beasts; they are the ancient, primordial deities, the ones whom the Aesir supplanted eons ago. Ragnarok was the ultimate consequence of that ancient usurpation. The so-called "Dragon Shards" are the souls of these slumbering primordial gods.

Odin's goal is not merely to save Midgard, but also to atone. Using his fading power to create the Dragon Knights, he seeks not to establish a new pantheon, but to foster a group of Stewards who can merge the power of the Ancient Gods (the Dragons) with human courage. The final conflict is not against a single monster, but against the residual, chaotic energy of Ragnarok itself. Kael and his companions must make a choice: to become the new rulers, or to gracefully return the world to its intended, balanced state—by assuming their Semi-Dragon forms as Stewards, using their power for restoration and protection, not domination.
