To Fulfill Our Promise

A man found a comet stuck beneath the forgotten land, and as years went by they built a mutual companionship. The man asked the comet for a favor and the comet accepted, promising to fulfill it. As time goes on, the man would later pass away due to old age, and days later the comet would also slumber. Years go by and the comet would find itself 10 years in the future, fulfilling the man's forgotten promise.
