There could be a variety of main characters. It might be a hermit who has made the forest his home. He has a deep connection with the forest and all its elements. Or it could be a young child who ventures into the forest out of curiosity and has to face the challenges and wonders there. Another possibility is a ranger whose job is to protect the forest and he encounters some sort of mystery or threat within the forest.
There might be a magical being like a forest spirit. This spirit could be the guardian of the forest, guiding or hindering those who enter depending on their intentions. It could have the power to control the elements within the forest, like making the trees grow or the streams flow in different directions.
There might be a guide figure as well. This could be an older person, like a wise old man or woman who has some knowledge about the forest and the mysterious thing in it. They could help the main character navigate through the challenges presented by the forest and the 'thing'. For example, they might give advice on how to avoid danger or how to approach the 'thing' safely.
