Hello menace123
You certainly write a complex and thoroughly explored theme here. The arc is good as is the character development for Cedric. There are some issues though.
The plot is very similar to that of a popular TV show, Game of Thrones. While plagiarism of the story is not a technical issue (copy word for word) still the theme and narrative very much resemble the show. It almost seemed as though it was taken from the show, although obviously it was not. Originality is important in writing. This might be described as lacking originality.
Also, the story is a bit improbable. The invitation, the princess escaping, the dragon, the lucky escape--it's hard to accept, even in a fantasy fiction piece.
However, your story is cohesive and organized.
Thank you for sharing this with us, @menace123, and for engaging with other authors.
