In "Season Eight" (2007–11), it is quickly established that Buffy is not living with the Immortal in Rome as previously suggested in "Angel"; this is simply a cover story to ensure her safety as she is now the leader of an army which recruits and trains Slayers to deal with demonic threats worldwide. However, a mysterious group led by the masked villain Twilight believe the Slayers themselves pose a danger to mankind and the natural order. In "Wolves at the Gate", a lonely Buffy shares a sexual encounter with a younger Slayer Satsu; the relationship ends soon after when Satsu accepts that Buffy does not return her romantic feelings. The time travel story "Time of Your Life" acts as a crossover with "Buffy" spin-off "Fray"; Buffy is kidnapped two centuries into the future and meets her eventual successor Melaka Fray and Fray's vampire twin brother Harth. These events have been orchestrated by a villainous future version of Willow, whom Buffy reluctantly kills to return home. The tensions between Buffy and Twilight's respective armies eventually erupts into a full-scale war in Tibet; Twilight is unmasked as Angel being manipulated by enigmatic cosmic forces trying to destroy the universe and usher in a new dimension where Buffy and Angel will live together in paradise. However, Buffy rejects Twilight's influence and saves her world by returning to the ruins of Sunnydale and smashing the Seed of Wonder, cutting Earth off from the source of all magic in the process. During these events, Buffy reunites with Spike, Giles is killed by a Twilight-controlled Angel, and the Slayer army is dissolved; Buffy moves to San Francisco with her friends to grieve their losses.
