As Carlissa falls and the Warlord threatens all of the Eastern Continent, the leaders of nation after nation, fearing conquest by his infernal army, sue for treaties of peace. Only one leader stands alone to defy the Horde: Tarnas Acheron, the Peregrine King of Mount Cassandra. Consumed by wrath over the murder of his daughter Elena and her family, the lord of the mountain elves has sworn vengeance against the Black Magus and his demons.
But can he survive their attack when even his wife, Queen Talina of Elde, fears to stand at his side? And will Robin and the resistance remain in the shadows while the Peregrine King fights a lone war against the Dark in their name? Or will they risk a final defeat by coming out of hiding to join his cause?
