Is a prequel first or last?

Could you please clarify your question for me? Are you asking about the order of a prequel in relation to the original work, or something else entirely? If you're asking about the order in which a prequel should be read or viewed, typically a prequel is a work that takes place before the events of the original, so it would come first in terms of chronology. However, it's possible that someone may choose to read or view the original work first and then go back to the prequel for additional context or backstory. Ultimately, the order in which you consume these works is up to you.
