Thalia fought through Thraben with Traft's spirit helping her, while former protectors and fellow cathars had become horrors. Her attempt against the fused Bruna and Gisela ended with her gryff dead and her own body pinned and injured.
Sigarda intervened but was seized by her sisters. Traft helped Thalia recover and wield Avacyn's broken spear; borrowed angelic wings brought her back into the fight.
Thalia's strikes freed Sigarda and brought the fused creature down. The moment preserved the sane archangel without restoring her sisters. Above the continuing battle, Emrakul's approach drove another surge of creatures forward. Their real victory had not ended the invasion.
