After escaping from Serrok Castle and the Kingdom of Istamid as a whole, Kaz, Rhenor, and Elaya find themselves marooned on an island after being shot down by people from a town called Rethan-a strange place where no magic can be used. While they mean no harm to Elaya or Rhenor, the same cannot be said for Kaz. As the two do their best to rescue their friend, though, it slowly becomes clear that Rethan's plans for Kaz are much more sinister than they originally seemed. The town hides a dark secret, and it's up to Rhenor and Elaya to make sure Kaz doesn't end up being its latest victim.
