I'm not sure specifically as I haven't read this exact novel. But generally, it might be about a warrior who is exiled perhaps due to jealousy or some political intrigue involving the hero and his lover. Maybe the hero feels threatened by the warrior in some way related to his relationship with his lover.
Well, it seems the warrior had some sort of conflict with the hero and his lover. Maybe he knew a secret that could expose them, and that's why they got rid of him.
Perhaps it's a story of redemption, where the warrior overcomes the odds and eventually finds a way to clear his name and return to his rightful place. Or, it could be a dark and tragic narrative of a broken soul struggling to survive in a hostile world.
I'm not sure specifically as I haven't read it. But generally, it might be about a hero who has been exiled and his adventures in exile, like facing new challenges, making new allies or enemies, and trying to find his way back or achieve something great in that exiled state.
Since I haven't read the novel, I can't say for sure. But it's likely to have the exiled hero as one of the main characters. There may also be characters who play important roles in his exile journey, like a mentor he meets in exile or an antagonist who makes his life difficult.
