Speed + Magic

Thinking maybe she could outpace the spell, Elspeth began to run. She enhanced her speed with spellcasting, and the shapes of the corridors changed. Instead of right angles there were curves and meanders. She could hear the footfalls of something coming up behind her fast. There was a howl of rage, and she saw a pack of Nyxborn wolves chasing her down. As she glanced over her shoulder, an arrow narrowly missed her head. A Nyxborn nymph rode on the lead wolf, and she was unleashing another arrow. Elspeth veered right down another corridor as the arrow whizzed past her.
