“Do you know who I am … was?”
“Yes,” the demon said. “Lord Sargatanas knew even while he spoke with you. It was his Art, his special skill, to know. When he gave me my instructions he told me that I could, at my discretion, give you your self back. He gave me a glyph for this purpose, Boudica.”
As she heard that name, she saw the demon raise his hand and from it a simple three-character glyph flared from his palm. This he gently pushed forward and, moments after it vanished against her skin, she felt as if a slight breeze brushed through her chest.
The soul stood transfixed, unable to speak as, for a fleeting moment, she smelled something forgotten, something so sweet and aromatic that it overpowered the acrid pungency of brimstone and set every fiber of her soul alight. It was the unmistakable earthy scent of the forest, and with it, like countless leaves falling in seamless layers, her memories came back to her. She closed her eyes and for a time the faintest smile played upon her mouth and then, quite suddenly, her face grew grim.
