The base of Twilight's horn had begun to throb, and she was covered with a light sheen of sweat. She took a deep breath, and with a soft, unconscious snarl, dove back into the seemingly endless pool of magic within her. She let the power fill her, and she embraced it. As the bolts of energy left her horn, she forgot about her headache. As the air rippled with magical explosions that sent bones and stone flying across the room, she forgot about the sweat covering her body. And as the skeletons got too close, and she deflected them with magic and the adrenaline coursed through her body, she forgot about her fatigue.
