The witch of time

Previously

…The grimoire in Elias's hand seemed to pulse with a faint, internal light, a silent warning. My magic flared again, this time with a desperate, protective surge. The ancient stones of the tower seemed to hum in response, a low, resonant vibration that filled the air. Elias looked from me to the grimoire, his face a mask of confusion and dawning fear. The mystery of my existence had just deepened, and the consequences of his arrival were beginning to ripple outwards, far beyond the quiet walls of my lonely tower. The glimpse of time he had offered me was already threatening to pull us both into a maelstrom.
