Zarco was a demigod from the mortal world who had ascended to Valhalla after completing the trials of the dragons. It was one of the rare times when the giants were not in charge of the gate of Valhalla.
He was also among one of the earliest demigods who were guided by the dragons and the elder who was in charge of him had limited experience with controlling the gate.
So he had made a slight error in choosing the destination and Zarco had found himself in a danger zone called the Ocean of Bones. As an alchemist who specialised in treating living beings, the bone creatures of the Ocean of Bones were troublesome enemies for him.
So Zarco struggled against them for over a hundred years and finally managed to escape this hellhole. But in that process, he suffered from several terrible injuries and one particular injury among the was extra troublesome.
