I'm not sure exactly who the main characters are without reading the story. But usually in a short story, there are one or two central characters that drive the plot forward.
It's possible that the main character is an explorer or a scientist. In a story involving a specific tree like the fever tree, they could be studying it or using it for some purpose. And there could be local characters who interact with this main character, providing different perspectives on the fever tree and the events in the story.
I think the main theme could be about survival. In many short stories, characters face various challenges and have to find ways to survive, and perhaps 'the fever tree short story' is no different.
It depends on the specific 'fever dream short story'. It could be a sick child as the main character, who is the one experiencing the fever dreams. Maybe it's an old man reminiscing about his past while in a feverish state, so he would be the main character.
As I haven't read the story, it's difficult to determine the main characters precisely. However, it could be that there is a young child who stumbles upon the fever flower in the forest. And there might be an older, wiser figure like a shaman or an herbalist who imparts knowledge about the flower to the child. These two could potentially be the main characters, with their relationship and the mystery of the fever flower driving the story forward.
I'm not sure as the story isn't described here, but it could be a gardener who takes care of the fig tree. This person might be central to the story as they have a connection with the fig tree.
Since I don't know the specific 'Trouble Tree Short Story', it's hard to say. But it could be a young adventurer who stumbles upon the trouble tree and has to deal with its consequences. Maybe there's also an old wise man or woman in the story who gives advice on how to handle the trouble related to the tree.
I'm not entirely sure without reading the story in detail, but it could be a young protagonist, perhaps a person who is at a crossroads in life.
Since I haven't read the story, I can't say for sure. But there might be a child who discovers the tree.
As the story isn't presented here, it's hard to determine the main characters precisely. But in a general bamboo - related story, there could be a character who discovers the bamboo tree in a forest or a field. Another character could be an old wise man who imparts knowledge about the bamboo's growth cycle and significance. There might also be a young learner who is being taught about the bamboo tree, and through this, learns some valuable life lessons.
Since I haven't read the 'the tree of life short story' specifically, it's hard to say for sure. However, it might be a gardener who takes care of the tree, or perhaps some mythical creatures that live in or around the tree. Maybe there are spirits associated with the tree that could be the main characters.
The main character is the fir tree itself. There might be other minor characters like the animals that interact with the tree or the people who come across it.
