Kate Beckinsale did not officially quit the "Underworld" series; however, she took a break after "Underworld: Awakening" (2012). She returned for "Underworld: Blood Wars" (2016), but her absence in subsequent projects was due to various factors, including her desire to pursue other roles and projects outside the franchise. Beckinsale has expressed a love for the character Selene but also a need for creative exploration beyond the series. As of October 2023, there have been no confirmed plans for her return to the franchise.

As of October 2023, there is no sixth "Underworld" movie confirmed. The most recent installment is "Underworld: Blood Wars," released in 2016. While there have been discussions and speculation about a potential sequel or reboot, nothing has been officially announced or released. Fans of the franchise are hopeful for new content, but for now, the series remains at five films.

As of my last update in October 2023, there is no movie titled "Underworld 2025" officially announced or released. The "Underworld" franchise includes several films, with Kate Beckinsale famously starring as Selene. If you're referring to a specific upcoming project or reboot within the "Underworld" universe, please provide more details or specify any recent developments, and I can help clarify!

In the "Underworld" series, Selene's daughter, Eve, is introduced in "Underworld: Awakening." She is a hybrid, born of Selene and Michael Corvin, possessing both vampire and lycan traits. Eve is crucial to the ongoing conflict between vampires and lycans, as her existence symbolizes a potential new evolution of both species. Throughout the series, Selene's primary motivation is to protect Eve from various threats, including the lycan leader, who seeks to capture her for her unique abilities. Eve's fate evolves with the storyline, but she ultimately represents hope for both races.
