The Hidden Enemy

The nearby town of Ash Falls has been attacked by a scourge of wyverns. Farebrook's town elders send Zae and Chiara along with a caravan of supplies to help. Ash Falls is badly damaged, but there is no sign of the scourge. Zae and Chiara, with their griffins Cirrus and Solandra, search for days but can't find them. When the scourge appears out of nowhere, they discover a new threat.
