Well, the title gives it away that the echidna and the shade tree are the main characters. The echidna is a mammal known for its distinct features and habits. In this story, it will be the focus of the action, most likely interacting with the shade tree in various ways. The shade tree is not just a passive element. It could be a source of protection, a place of discovery for the echidna. There may be no other characters at all, or there could be some secondary characters like small animals that also use the tree for shelter, but they are not as central as the echidna and the tree.
The main characters are most likely the echidna and the shade tree.
I'm not sure specifically as I haven't read this exact story. But generally, it might be about the relationship between the echidna and the shade tree, perhaps how the echidna uses the tree for shelter or some sort of adventure that involves the two.

Since I haven't read the '92 in the shade novel', I can't tell for sure who the main characters are. But typically, in a novel, the main characters are those who drive the plot forward. They could be people with different personalities and goals, like a young adventurer, an old wise figure, or a conflicted individual.
Since it's a fanfic, it could be that the main characters are various echidnas. There might be a heroic echidna leading the fight against an opposing group. Maybe there's an echidna with special powers related to the ouroboros. Or it could be that there are echidna elders who are trying to bring peace in the midst of the war and are the central figures in the story.
A brave Echidna warrior named Thorne could be a main character. He's known for his incredible strength and unwavering loyalty to his tribe. And for the Lamia side, there could be a clever Lamia named Lyra. She has the ability to charm her enemies, which comes in handy during battles.
A tough echidna warrior could be one of the main characters. He could be leading the echidna forces against the snakes.

There might be a human character in 'the old tree story' who has a deep bond with the tree. It could be a storyteller, a gardener, or a child who discovers the magic of the old tree.
