Arthur is a noble-born reincarnator searching for absolute immortality to avoid the terrifying fate he witnessed in the afterlife. Thanks to a failed spell designed by an unimaginative ancestor, he is able to glimpse a path leading toward immortality while laying the foundations to become the world's first necromancer. However, magic in the world of Nithe is as brutal and complex as the world itself.

Although Arthur would like nothing more than to focus his efforts on advancing his goals, the circumstances of his birth compel him to be an active participant in the world's happenings regardless of his desires. With death hanging around every corner, to attain absolute immortality, Arthur first needs to survive the cruel yet fantastical world he now inhabits.
