Buffy works primarily with a few new allies, including Robert Dowling, an SFPD officer who heads up an anti-zompire task force, and Billy Lane, a gay teenager who moved to San Francisco to support Buffy's cause. Later it is revealed that Anaheed is another Slayer who has been tasked with looking out for Buffy, and she takes Billy under her wing. Buffy is also briefly allied with Eldre Koh, an ancient demon whose mystical prison was broken along with the end of magic, and for this swears a debt of loyalty to Buffy. Koh reveals however, that his vendetta against his ancient jailer trumps his loyalty to Buffy, and betrays her trust. Later, on a mission with Dowling and Billy, Buffy finds herself transported to Los Angeles where she is approached by another ancient demon, Illyria (a character from the television series "Angel"), who recruits Buffy to a team dedicated to defeating Severin. Eldre Koh and Buffy's old enemy D'Hoffryn are also members of Illyria's council. Buffy, Illyria and Koh strategize to disarm and take out Severin. However, their plan fails and Severin is successful in draining Illyria of her abilities leaving her alive but powerless and stuck in the physical appearance of her human host body, Winifred Burkle. Having drained Illyria of her powers, Severin acquires her ability to freely travel through time, which he needs to resurrect his dead girlfriend. Soon after, Buffy discovers that Dawn (who was created from a mystical key in "Buffy" season five) is dying as a result of the end of magic. Xander—who has been struggling with his anger since Giles' death in "Season Eight"—blames Buffy for Dawn's predicament. Severin and Simone approach and ask him to steal Buffy's sole inheritance from Giles (the "Vampyr" book seen in "Buffy" episode one) so that they might use it to go back in time and avert the Twilight crisis which precipitated the end of magic. Willow returns from her journey with her powers and Buffy's scythe restored, but she can only buy time for Dawn, whose health is still failing. Xander appears to confess to Buffy of Severin's plan, leading the trio head to the Deeper Well in the English Cotswolds (a prison for ancient demons seen in "Angel") where they hope they can acquire sufficient magical reserves for Willow to restore Dawn.
