“Mr. Grey peeked around the corner and surveyed the corridor. It stretched off into dim infinity, dotted with floating globes of silvery light. Mr. Grey had been told that the globes were swampfire, encased in a timeloop charm so they were inextinguishable. He’d never even heard of swampfire, much less a timeloop charm, but then again, Mr. Grey had never been in a place quite like the Hall of Mysteries. He shuddered.”
