There was an odd message among the cluster of useless messages that interested him. It was a message from a slave asking for him to save them. They spoke at length about their situation and the reward they would give him if he saved them.
He shook his head and said, "Humans make for bad slaves. They just aren't resigned to their situations. Imagine the kind of trouble they will bring if they send this to heroes."
Then he frowned after thinking about the fact that someone sent him, whose identity as a villain is clear as day, for them to save him. They are offering a large reward, which is a reasonable motivator for him to save them, but he was still suspicious.
He touched his chin as he said, "I bet this is a trap for me."
He is not being narcissistic. Tempting a target with money is a common tactic to get a competitor. It is something that has happened many times before. There are many such stories about it online.
