What is an example of illusion in The Most Dangerous Game?

In "The Most Dangerous Game," one notable illusion is the way the island appears to be a paradise, luring sailors with its lush vegetation and beauty. However, this illusion masks the true danger of the island, as it is a hunting ground for the sadistic General Zaroff. The protagonist, Rainsford, initially perceives the island as a safe refuge but soon realizes it harbors deadly intentions. This contrast between appearance and reality underscores the story's themes of deception and survival.
