The Normal-verse Series by jAkL
Summary: Buffy is killed by the First at the end of Chosen. But that will not stop her from setting things right.
Fandom: Buffy the Vampire Slayer/Stargate SG-1 crossover
Awesome Women: Buffy Summers, Dawn Summers
Far Beyond Normal and Return to Normal are the two epic fics that make up the Normal-verse series. In Far Beyond Normal, Buffy is killed during the battle in the Hellmouth, and the First Evil takes control of her body. Buffy's "self" is transferred to Elizabeth Summers, a patient in a mental ward (as seen in "Normal Again"). But, as we soon find, Elizabeth's world is the Stargate 'verse. Buffy is bound and determined to return to her universe and stop the First from destroying all of reality. This Buffy is awesome, not just because of that determination, but because 1) she learns from those around her, and 2) she is playing a long game, and though it may not be clear at first, her every action is geared toward her endgame.
Dawn, on the other hand, is stuck in the Buffyverse, confused and angry as her world completely changes. Once she realizes what's happened, however, she begins her own plotting against the First's machinations. Dawn may have an important role in Buffy's plans as the Key, but it's Dawn the woman who makes the final attack on the First Evil even possible.
