Ghostale part 1

Long ago to kinds ruled the earth, humans and monsters. One day war broke out between them, humans were victorious.They sealed monsters underground with a magic spell. Those who ever climb the moutain never return but sometimes seen as a spirit or a ghost near they moutain, the next look they are gone. A human child one day climbed the moutain to do a suicidal attempt due to the place of hauntings she/he have seen. The child climbed that moutain to fall, but when the child fell they saw 7 children fall with them faded and hurt. They were ghost of the past children who fell down.

Also I do not own undertale or any of the art used
