After talking to someone about this, we came to the conclusion that this was written by a dragon. Here’s the reasoning: Me- It sounds like he killed his sister’s rider for some reason, which caused her to commit suicide. And now he’s probably suicidal. Possibly because he doesn’t have a rider of his own either.
Kyky- I think he killed his sister’s rider knowing she would commit suicide—which he regrets and is now admonishing himself for his evil deeds. So now i have to figure out how to write this into a short story.
I don’t think that you should explain poetry so much as let the reader find the meaning from it. That is the lovely thing about poetry. It welcomes many meanings.
