The world's most dangerous zoo provides attendees the experience of a lifetime: witnessing the fearsome manticore feeding, or the speedy mystdrakon race across its dome at blurring speeds, or the pack of brutal fyrehounds hunting across a sandy landscape-all within the safety of the highly secure domes. But success breeds complacency... Pax and her friends are attending the grand opening of the newest section of the park: Other Realms. Intent on bringing in a new horde of attendees, the zoo custodians are opening up new domes with supernatural creatures that inspire nightmares and challenge the very limits of security. When the presence of a single, unique creature upsets the carefully constructed and overlapping systems that protect the guests, a cascade of failures turns the exciting day into a fight for survival.
