Perhaps the theme is about discovery. If new words were added each day, it might be like the discovery of new ideas or elements in a story. The story could be about a character exploring a new world, and each day's word represents a new discovery within that world. For instance, if one day the word was 'mystery', then a mystery element could be introduced into the story's plot.
The theme might be related to time. Since it's associated with day 156, the story could be about the passage of time and how things change over that period. The words added each day could reflect different moments in time, like 'dawn' for the beginning of a new phase, 'midday' for a crucial point, and 'dusk' for the approaching end of a situation in the story.
