The main themes in the story of the three trees could include hope and purpose. Each tree may have its own aspiration, like becoming something great in the future. Adaptability is also important. They need to adapt to the changing environment around them, whether it's a change in temperature or the amount of sunlight. And then there's the theme of interconnectedness. Their roots are connected underground, and their branches may touch in the air, showing that they are linked and depend on each other in some ways.
Since I don't know the exact '3 trees story', I assume the main characters are three trees.
The story of the three trees was mainly about the dreams of the three little trees and their fate when they grew up. The first tree dreamed of becoming a treasure chest full of treasures, the second tree dreamed of becoming a sturdy ship, and the third tree dreamed of becoming the tallest tree in the world. However, after years of growth, loggers came to the mountain. The first tree was cut down and made into a manger, the second tree was made into a fishing boat, and the third tree was cut down. Therefore, the dream of the three trees did not come true in the end.
Since it's about three Christmas trees, the main characters are likely those three trees themselves.
The main characters in the three trees story are the three trees themselves. They start with their own aspirations. For example, the first tree has the ambition to be a magnificent ship, the second wants to be a throne for a great king, and the third wishes to stay put. As the story progresses, their lives take unexpected turns, but they remain the central focus throughout the narrative.
I assume the main characters would be the three Christmas trees themselves. They could each have their own personalities, like one being jolly and bright, another being a bit shy, and the third being bold and showy in their own ways.
Nature and its power is also likely to be a major theme. The 'Black Sea of Trees' represents a powerful natural environment. Novels could focus on how humans interact with it, whether they are in awe of it, trying to conquer it, or being consumed by it.
One possible theme could be contrast. The palm trees, which are typically associated with warm, tropical climates, are in the snow, which is cold. This contrast can symbolize the meeting of two opposite worlds or ideas.
There could be a variety of main characters. It might be a group of children who were inspired to plant trees for peace. Maybe they learned about the importance of peace and the environment in school and decided to take action. Or it could be a story of a group of refugees who, in their new land, started the 'Trees of Peace' project as a way to find a sense of home and peace, with each person having their own story of struggle and hope that led them to be part of this project.
I don't know the story precisely, but I think the main idea could be about the connection between Christmas trees. It might be about how they care for each other and create a special relationship during the Christmas season.
The main characters are the three little trees.
