Aot Fezim and his squad of mercenaries restored their damaged reputation and found new soldiers for the thinned army. But one more problem remains. Too many griffin mounts have been killed in past battles. And if the name “Brotherhood of the Griffin” is not just an empty phrase, we need to find a replacement for them. The Rashemen witches have griffins - and the brave souls who defeat the undead ravaging the lands of this country will be able to take them. Aot and his squad, like others, intend to take part in this battle for the war beasts. But things again turn out to be not what they seemed. Epic battles between mercenaries and berserkers involving airships punctuate this story in the barbaric lands of oracles, nature spirits and talking beasts.
