Warrior Nun

There, she's greeted by Tarasks, seemingly the personal guardians of Reya herself, and when she eventually comes to in the midst of Beatrice and Vincent ...

The last we see of Beatrice is as she’s leaving the OCS, though we don’t know exactly where she’s going. Adriel recovers from the explosion, but once the power-dampening cross is taken down and the Halo starts working again, Ava is able to use it to summon the Tarasks into this realm. Instead Ava has to fight Adriel and Lilith both, while Adriel tries to drag Reya through the Arc so he can imprison her. Ava shares a goodbye kiss with Beatrice and heads off to meet Michael, but Beatrice isn’t having that, and figures out where the Arc is so she can try to intervene in what’s about to happen. Michael sneaks off during the parking lot shootout, and Ava later reveals that she intentionally told Jillian to lie about the location of the Arc within the cathedral so that she could break off and sacrifice herself to save the others. There, she’s greeted by Tarasks, seemingly the personal guardians of Reya herself, and when she eventually comes to in the midst of Beatrice and Vincent bickering about what’s going on, she declares that she knows just what to do.
