so darkness i became

The complicated relationship between a Witchkiller and Death throughout the centuries. “I am not often surprised anymore.” Her voice sounded tired, but there was a curious humour to her tone that made a small inkling of pride bloom within Agatha. She liked amusing this woman. “Have you done this before?”“No,” Agatha answered honestly. No part of this night had gone as she had expected it.“Will you do it again?” This time there was no mistaking the small smile on the woman’s lips this time. Agatha noticed for the first time that she was very pretty.

Basically the first chapter is just inspired by that one line Agatha says to Wanda in Wandavision about necromancy being a non-starter and me loving the idea of Agatha always being interested in death and dark magic, even before Rio.
