Another theme could be change. A half - moon is a stage in the moon's cycle, so the story may be about a character or situation in the middle of a change, like the transition from one state to another.
The theme of duality could also be present. The half - moon has two parts, light and dark. So the story could deal with the coexistence of opposing forces or aspects within a character or a situation, such as good and evil, or hope and despair.
Well, without reading the actual 'half a moon short story', it's hard to say for sure. But generally, a half - moon can symbolize mystery. Maybe the story is filled with mysterious elements, and the half - moon is used as a metaphor throughout the narrative to represent the unknown or the hidden parts of the characters' lives or the plot.
One possible theme could be mystery. The full moon often creates an air of mystery, and the story might revolve around something unknown that occurs on that night.
It could be about time, as the numbers might suggest something related to a specific time like December 1st. Maybe it's about missed opportunities or new beginnings associated with that time.
One possible theme could be adventure. The girl going to the moon is likely to face many new and exciting situations that test her courage and ability to adapt.
It could be about love. Love is a very common theme in short stories, like a short-lived romance or unrequited love.
One possible theme could be the struggle between good and evil. Jesus often represents good in religious context, and the 'dark moon' could symbolize the forces of evil or the unknown. Another theme might be redemption in the face of darkness. The contrast between the light associated with Jesus and the darkness of the moon could be used to explore how characters find their way to salvation.
A half - elf might have a back story where their elf parent was from a noble elven court. Maybe their elven mother or father fell in love with a human during a diplomatic visit to a human kingdom. The half - elf was then raised between two worlds, not fully accepted in either the elven or human society, constantly feeling like an outsider but also having a unique perspective on both cultures.
One possible theme could be survival. Just like in Half - Life 2, the dog would have to face numerous threats and find ways to stay alive in a harsh environment.
One possible theme could be self - acceptance. If the girl has some sort of disfigurement or difference on half of her face, the story might be about her coming to terms with how she looks.
One possible theme could be time management. Since it's focused on a day and a half, it might show how people make the most of a short period of time.
