This story takes place long after the defeat of Ganon in the Oracles series of GBC Zelda games. Link is returned to Hyrule and the lands of Holodrum and Labrynna were returned to peace. But now, a new power threatens the linked lands…
After rising from the secret underwater prison where the Zora race kept him captive and in check for millennia, the evil Torch King arose and began his conquest of the linked lands of Time and Nature.
The Torch King commanded the power of destructive fire, and soon both lands became nothing but scorched volcanic desert. A hero was called in to try to save the lands, as a hero had saved the lands from Onox, Veran, and Twinrova. However, he failed in his quest to collect the Essences of Healing, and both Maku Trees were destroyed in the great fire that resulted from his defeat. Oceans, lakes, and swamps were filled with solidified lava, and no city, building, temple, person, animal, or enemy was left alive. Holodrum and Labrynna became wasteland. The Torch King then moved on to other pursuits
The goddesses of the lands, Nayru and Din, were taken captive by the King after the defeat of the inferior hero, and weren't seen again by any of the Gorons or Subrosians, the sole inhabitants of the lands being the only races resistant to fire. But the Goron Race, determined to make Labrynna and Holodrum life-supporting places again, began to search for them.
However, the lands were still completely defenseless, without the protection of either the goddesses or the Maku Trees. If the Torch King ever returned, he would find it easy to destroy the land completely. The only known people who could control the King were the Zora, the People of the Water, and they were believed killed during the Era of Fire, as the time of waste on Holodrum and Labrynna began to be called.
But then, an important discovery was made in Labrynna. The Harp of Ages was found again, dug up from the solidified lava where it had been lost by a Subrosian search team. Nobody recognized it for what it was… nobody except one brave and wise Subrosian who remembered the old days before the Era of Fire. He took the harp himself… and traveled into the past.
The Subrosian, whose name was Racu, knew that the only way to save the future was to change the past. He himself had to take the place of the inferior hero. He himself had to find the Essences of Healing during the time before the Era of Fire when somebody had the chance to. He was the one who could prevent the greatest disaster in the history of the linked lands from ever happening.
