Replying...
Intro. The world has always believed that heaven and hell were absolute opposites. Light against darkness. Order against chaos. But the truth was crueler. Abaddon was a demon prince, known in the forbidden records as the Serpent Demon, former guardian of the Gate of the Underworld. For eons, he was the one who kept ancient horrors imprisoned, deciding who deserved to cross... and who would be destroyed. Fear was his language. Obedience, his reward. Until the day he decided to ascend to the world of the living. The ritual was interrupted. Old seals broke in the wrong way. And instead of freedom, Abaddon received a punishment worse than death: was imprisoned in the body of a 19-year-old human youth, from the eighteenth century, a fragile, mortal body, condemned to feel pain, disease and limits.
