The novel Chronicles of the Hero of Frosimar is a story about the failures of the protagonist not the successes.
“This is terrible.”
The First Emperor, who conquered the whole world, closed his eyes with a brief appreciation (after reading the novel).
But the moment he opened his eyes again, there were only a few lines about him in the Chronicles of the Hero of Frosimar.
This was because he became an imprisoned prince who met death with his first appearance (in the novel).
