EP1, or Episode 1, typically refers to the first installment of a series, whether in television, film, or other media. It serves as an introduction to the main characters, setting, and overarching plot. This episode often establishes the tone and style of the series, engaging viewers and setting the stage for future developments. In many cases, EP1 is crucial for character development, as it provides background information and motivations. For example, in a series like Star Wars, EP1 introduces key figures such as Anakin Skywalker and sets up the conflict that drives the narrative forward.
