I'm not sure specifically as there isn't much information here. It could be about a particular piece of wood that has some significance related to a real - life event, like maybe a tree that was part of a historical event or a wooden object with a real - story behind it.
It might be a story centered around a wooden item or place made of wood. For instance, it could be a wooden ship. The true story could be about its construction, the adventures it had on the high seas, the people who sailed on it, and how it influenced trade or exploration. Maybe it was involved in a famous battle at sea, or it was a merchant ship that had a unique role in the economy of a certain region. There are so many possibilities when it comes to a story based on wood.
