A story I've had in the back of my head for a long time; an origin story about the Grim Reaper, in which the Grim Reaper selects a child of the living to be his heir. The boy and his mother are brought to the underworld where the boy begins his transformation and training to succeed his predecessor.
The text at the beginning reads: The gentle passage of time. The steady path of life. These are no more than mere circles, flowing and turning over and over again. With a moment that forever imprints on your heart, the next moment may be like any other. Time goes by without a care. Embrace the season.
