Publisher's summary

The minotaurs are dead. Mistress Nava has no choice. She'll have to take matters into her own hands to put an end to Elorion and his friends.

Join Elorion as he searches for the power to challenge their deadliest enemy yet. Whether he finds it inside himself or in some legendary weapon, will it be enough to end a Mistress level monster once and for all?
