I'm not sure which second part of the Chronicles of Narnia you're referring to. The Chronicles of Narnia was a very popular novel series. The first novel told the story of how the protagonist, the Lion King Simba, established his career and kingdom on the planet of Narnia, which was colonized by humans. The second, usually referred to as After the Lion King, was about Simba's son, Jason, who inherited the throne and began to face challenges from humans and enemies from other planets. However, the details of the content may vary according to different translated versions and editors.
