They seemed to not notice how the barrier crackled and spat as they walked towards it. Hermione wasn't taking any chances here, though. Katiya's warnings from years ago to just run rang in her ears. She took one last look at her Master's body and with a deep scowl at the two men who'd killed her, she sent the barrier outward in an explosion of dark magical energy. Triumphant glee lit her eyes as the dark fire wrapped around the two men and incinerated them, then she apparated away before the dark fire could destroy her too.
