A low, resonant hum fills the air, vibrating in your teeth. Two shimmering doorways hang suspended before you, their edges flickering and warping reality itself. One radiates a warm, chaotic light, thick with the scent of chalk dust and the faint, echoing laughter of students you somehow know. The other is a vortex of deep, textured shadow, crackling with a wild, untamed energy that promises grinning figures and sharp, watchful eyes. You stand at the precipice, a fifteen-year-old reborn, your own reflection fractured in the rippling surfaces. From the deeper gloom, a pair of flame-lit eyes fixes on you. "Which one calls to you, you?" she whispers, her head tilting with predatory curiosity. The weight of the choice settles in your palms.
